Shelf-life management is an important but tedious measurement. Agr will feature several products that provide immediate determination of the permeability and shelf-life performance of newly produced PET bottles. These products make it possible to effectively manage (in real-time) a bottle’s shelf-life performance for oxygen ingress, CO2 or water loss.
Pressure and volume
Whether your final product is packaged in a PET bottle, PET keg, aluminum bottle or glass bottle, accurate volume and proper pressure performance is paramount to the efficacy of the finished beverage container. Agr offers several testing products designed to aid bottle makers and beverage producers manage pressure and volume. The Agr PPT3000 offers a versatile solution for measuring volume expansion and pressure performance of containers manufactured from PET. Unlike other pressure testers, The PPT3000 actually simulates the rapid rise pressure profile that a container experiences during the filling cycle, providing valuable data that can be used to prevent filling line downtime due to premature pressure breaks. The SPT2, Agr’s latest addition to its product group, is an automated glass bottle testing system that performs precision volume measurement as well as pressure testing up to 1000 psi. Configurations are available for automated laboratory applications or along the production line as part of an automated sampling station.

American Glass Research, a division of Agr International, Inc., recently continued it’s release of legacy white papers that have been completed throughout the last several decades. This release includes papers from 1959-1961. In 1959, Dr. Richard Mould in collaboration with Mr. Russell Southwick, both of Preston Laboratories (the predecessor and foundation of American Glass Research) prepared two papers entitled “Strength and Static Fatigue of Glass under Controlled Ambient Conditions, Part 1 and 2.” These papers further defined glass strength and how it should be properly measured. Dr. Mould continued the topic with two more papers, Part 3 and 4, in which he further defined critical aspects of glass strength.
Agr’s new MBTxt series of portable thickness gauging devices offer compact size, high precision and a measurement range up to 24mm – perfect for measuring glass
The MBTxt is the latest in a line of small, portable thickness gauges offered by Agr International, Inc. This compact device features an advanced digital architecture and is capable of achieving extremely precise thickness measurements over a wide range. With a low range resolution of 0.1 μm, it is ideal for the packaging industry, especially the intricate requirements of bottle and container manufacturers. However, its applications are not limited to containers. Since the MBTxt can be used to measure all types of non-ferrous materials up to 24mm thick, it is also equally suitable for automotive, aerospace, medical and similar applications where very accurate measurements are required yet portability is essential.
Measuring glass containers
At times, glass bottle and container designs can be complex. With that, acquiring accurate thickness measurements in critical locations can be quite challenging. The conical shape of the MBT sensor probe facilitates measurement in very intricate locations. This feature on the MBTxt probes, the high accuracy, and wide measurement range create a powerful measurement system that is aptly suited for measuring the diverse range of products in many glass production facilities. Routine bottle sidewall thickness measurements, difficult areas such as bottle heel, base and finish regions as well as heavily decorated areas can be achieved with ease and precision. Even extremely difficult-to-measure regions such as corner areas on non-round containers can be measured with the same accuracy as routine sidewall measurements.
In addition to measuring critical areas and complex shapes, the MBTxt can accommodate a range of material thicknesses. The availability of two easily interchangeable sensor probe options and the wide selection of target balls provide the versatility to measure very thin materials as encountered in tubing products and small vials with a low end range of 0-2mm (0.1 μm resolution) to applications where the material is very thick such as in champagne bottle bases, candle ware and similar products.
The MBTxt is available in two models. The MBT7200xt, a basic version, includes real-time measurement, display of minimum and maximum thickness and storage of up to 100,000 values. The MBT7400xt, an advanced version, includes the same capabilities plus statistical graphing, trending capabilities and an expanded database. Interchangeable sensor probes are available for both units making it possible to configure the measurement range and precision appropriate for the application. A notable feature of the MBTxt is its expanded measurement range which is over twice the range of previous offerings.
Based upon the “Hall Effect” principal, the MBTxt features an advanced sensor design that works in conjunction with specially treated target balls to achieve the highest precision and repeatability. Balls of this design provide improved measurement reproducibility of up to 0.5% over untreated balls. The new “xt” version offers two sensor options, with ranges from 0-9mm and 0-24mm. In addition to a re-designed sensor, the MBTxt is provided with a wider range of target balls, including specially configured “magnetic” balls, to facilitate greater flexibility and precision over an expanded thickness range.
Advanced probe design
One of the most profound features of the MBT7200/7400xt Gauging System is in the design of the sensor probes. These incorporate a process called “integrated digital signal processing”, where all measuring signals are created and completely processed inside the sensor itself. Only completely processed digital readings are transferred to the base unit for display, statistical analysis and storage. Unlike analog devices, error influences on the measuring data during transfer over the cable (signal to noise ratio) are substantially reduced. This design ensures that measurements are true with the highest accuracy.
Hardened probe tip
The sensor probes on the MBTxt incorporate stainless steel housings and hardened carbide tips. This design provides for a long service life and limited wear to the probe tip even when working with hard materials such as glass. This is particularly important in the glass container industry.
Multiple calibration modes
In order to provide the most versatility with the highest accuracy for the given task, a selection of calibration modes are included with the MBTxt. Available calibrations include a factory mode for quick and simple measurements, Zero point calibration (zero only) and multi-point calibration (zero + 1-4 points) for the highest accuracy. Once calibrated, the system’s “calibration memory” retains the calibration even with the unit turned off.
The MBTxt devices are battery operated and completely portable. The base unit is sized to fit in one’s hand and the combined base unit and probe weigh less than 1 Kg (2.2 lbs.). Additionally, each unit is supplied with its own carrying case to house the base unit, probes and accessories making it easy to transport to any location.
The internal data logger and statistical functions of the MBT7400xt facilitate data collection in production areas and QC laboratories, making it an ideal tool for data-gathering applications. A large digital display permits the operator to easily view current thickness readings as well as minimum and maximum measurements. Stored measurements can be transferred to other devices via an RS232 or USB connection. An optional foot switch is available for hands-free data capture.

Pressure Testing, the right way
Regular pressure testing is essential to determining the integrity and performance attributes of PET bottles destined for pressure applications. Simulating real-world conditions is the only way to understand how bottles will perform under pressure during filling, in the warehouse and through retail channels. Without a proper pressure testing regimen, blowmolding problems can go unnoticed leaving bottle performance to chance, and with it, consequences that can be costly if bottles fail during filling or other downstream processes.
The science of pressure testing
The whitepaper, “Real World Pressure Testing of PET Containers”, provides an insight to the science behind PET bottle pressure testing and its relationship to bottle filling. This paper discusses the container filling process and the forces that bottles experience, as well as the role that pressure and volume expansion testing play in this process.

Agr’s Davide Bartoli, Regional Sales Manager, recently was a featured speaker at the MEAPET 2017 conference held February 21-22 in Dubai. MEAPET is an annual conference regarding PET business for Middle East and African markets. Mr. Bartoli’s presentation focused on Agr’s global presence and it’s 3-step approach to improve quality and profitability in the production of PET bottles. The presentation generated high interest in the Process Pilot product. Bartoli met with delegates from Middle East, Africa, Asia and Europe.
The three-day Beviale Moscow is currently underway. As part of the event, PET Arena has a dedicated section with individual topic island areas for companies directly involved with PET. Agr Regional Director, Aleksander Broda, is participating in the PET Arena area along with providing presentations on the optimization and light weighting of bottles by using Agr’s Process Pilot systems.
Nestlé Waters’ Sanpellegrino Group produces five brands of mineral water on twelve bottling lines in seven plants spread across Italy. These multiple operations are all guided by an overarching commitment: to deliver a consistent customer experience associated with each brand.
A major aspect of the customer experience is bottle performance, from grip and handling to cap removal and pouring. Sanpellegrino goes to great lengths to ensure that every one of the millions of PET bottles it manufactures will conform to brand expectations.
The key is exacting control of blowmolder operations, achieved with Agr’s on-line thickness measurement technology, the Process Pilot® Automated Blowmolder Control system. Process Pilot manages the blowmolder to virtually eliminate the effect of the process and environmental variables that can impact bottle material distribution, from fluctuations in weather and humidity to the differences between daytime and nighttime plant temperatures.
Not only does the Process Pilot measure every bottle for changes in material distribution, but it also controls the blowmolder proactively to make sure the right amount of material winds up in the right place.
Process Pilot proved its utility in an early light weighting initiative undertaken by Sanpellegrino’s premium Levissima brand, described as “Italy’s favorite local mineral water” and sourced from a mountain village in the Alps. The first bottling operation in Europe to deploy the closed loop Pilot system, the Levissima plant targeted a 22 percent weight reduction for its half-liter round bottle blown on a Sidel Series II Combi blowmolder—an enormous opportunity for material cost savings.
Even with a stable history running at close to 40,000 bottles per hour, this was a major challenge for the integrated blowing and filling line. Lighter bottles produced on faster machines have a much narrower processing window. To deliver on customer expectations, bottle production has to strike the right balance between performance and weight.
“With the Process Pilot installed on this line, managing the process, we were able to reduce the weight of our half-liter bottle to 9.5g while maintaining a very stable process,” relates Sanpellegrino’s Fabio Chimetto, Applications Group Packaging Manager.
As part of a corporate-wide move toward standardized production lines, Sanpellegrino recently installed three additional Agr Process Pilots. One of these will be mated with a new Sidel Matrix Combi blowing/filling/capping system as the company replaces independent equipment with a modern, integrated approach.
A project on tap for the new configuration is a further weight reduction in a 2-liter square bottle, down below 28g. Given Sanpellegrino’s vast bottle volumes, the initiative promises significant savings in material. Still, it can only move forward as long as the light weighting is accomplished without compromising bottle performance. The filled bottle, weighing two kilos, must remain convenient and reliable in consumer use–despite the shrinking margin of error in the blowing process. Having confirmed that Process Pilot’s automated controls maintain the desired material distribution throughout the production run, Sanpellegrino is confident of light weighting success.
“The total cost reduction potential provided by Agr’s Process Pilot in labor, energy, scrap, and material looks to provide for rapid payback and offers a competitive return on investment,” Mr. Chimetto comments.
The Process Pilot system enables Sanpellegrino to align efficient, advanced production lines with the customer-centric focus of its brands’ marketing strategy. “What is right for the consumer is not automatically the lowest weight,” Mr. Chimetto concludes.

American Glass Research, a leader in consulting, training and analytical services for the glass packaging industry since 1927, is located in Butler, PA, USA and is a division of AGR International Inc.
In the works for several years, Agr International, Inc. has announced the commercialization of its CrystalView™ product for optimizing the material properties of PET bottles. The introduction of the CrystalView product further expands the capabilities and the potential of Agr’s Process Pilot® product group well beyond the measurement and management of material distribution. With this product, bottle manufacturers now have the means to run the coldest possible process in order to optimize bottles material properties (orientation) while maintaining target material distribution. As a result, the best strength to weight ratio for a given bottle design can be achieved, improving overall bottle performance and at the same time, reducing costs.
The CrystalView measurement system offers a simple, reliable and hands-free means to accomplish the optimization of PET material properties without overstretching or going beyond the temperature boundaries that cause molecules to break and create pearlescence. The CrystalView system manages the process to the point where it is “just right”; avoiding the creation of pearlescence by detecting the very edge of where the process gets too cold and pearlescence begins to form. With CrystalView, it is possible to reduce the preform processing temperature to the ideal processing point (as much as 10 deg. C) for a given bottle design.
The CrystalView measurement system incorporates a set of discrete vision components that are mounted inside a reheat stretch blowmolder. As bottles exit the mold, the CrystalView system scans every bottle for the onset of pearlescence. During operation, sophisticated control algorithms incorporated into the CrystalView system actively monitor the levels of pearlescence. In conjunction with the Agr Process Pilot automated blowmolder management system, and based on a learned mathematical model that identifies the ideal control variables, adjustments are continuously made, including preform temperature, to manage bottle production to the point where the PET material properties are fully optimized, at a level just before the onset of pearlescence.
Improved bottle performance
Optimization of material properties makes it possible to create stronger, better performing bottles. This is evidenced by recent field studies performed in production conditions on bottles manufactured utilizing the CrystalView system. Test results showed significant improvements in bottle performance (as much as 38%) over bottles produced on the same blowmolder without the aid of the CrystalView system. Some examples of the improvements experienced during this study include:
- Shelf Life increased 10%
- Top Load increased 17%
- Volume Expansion (Creep) reduced 38%
- Burst Pressure increased 17%
- Oxygen Transfer Rate performance improved by 7%
- Squeeze resistance increased by 7%
The CrystalView system also offers the potential for significant savings along with improved bottle performance in a number of areas including blower energy consumption (from 7-10%), materials savings through expanded light weight potential and Improved downstream efficiencies as a result of decreased downtime losses during filling and processing operations.
Three step blowmolder management
The CrystalView product is the third segment of the Agr Process Pilot blowmolder management product group. The Process Pilot product is based upon three fundamental concepts:
- Measure every bottle to identify variation,
- Control the blowmolder, proactively managing target distribution, to eliminate the effects of process variation
- Optimize the bottle structure for maximum performance.
The Measure and control portion of the Process Pilot program has been on the market for a number of years and boasts an installed base of over 200 systems. The CrystalView product fulfills the third segment, Optimization.
The CrystalView™ system is available as an add-on option to the Process Pilot automated blowmolder management system for all new purchases. A retrofit version is also available for Process Pilot systems currently operating in the field.
Agr’s Process Pilot automated blowmolder control system has proven to be a vital tool in the production of light weight bottles, while improving overall bottle performance and quality. It is unique in that it manages the blowmolder based on direct bottle measurements, on every bottle produced. By controlling the blowmolder based on direct feedback from bottle measurements rather than just blowmolder performance indicators, the Agr system can ensure that the final product has the desired quality and performance attributes in spite of environmental, blowmolder or material variations that occur during the production process. The CrystalView system further enhances the value of the Process Pilot product group.

The days of dealing with the drudgery of manual volume measurement is finally a thing of the past! AGR’s new SPT2™ automated testing system not only provides reliable and robust burst pressure testing, but it also delivers the means to perform accurate and repeatable volume measurement of glass container production on the factory floor.
Volume measurement plays an important role in the production of glass bottles. Not only is it an important quality check and a verification of regulatory compliance, but it is key indicator of the status of the production process. Accurate and timely volume measurements on a continuous basis through the entire production run can play an important role in the early detection and correction of process-related issues, helping to ensure consistent, high quality product and an efficient production process.
AGR’s new SPT2 provides brimful volume, fill point at a defined volume and volume at a defined fill point all in a single, automated test cycle on the factory floor. The automation delivers real productivity gains when compared to current manual methods performed in the laboratory. For example, the SPT2 performs a volume measurement of a typical beer bottle in 30 seconds from start to finish. This includes handling the bottle, measurement, data capture and documentation. Compared to an average of 2+ minutes for volume measurement in the laboratory using the gravimetric method, the SPT2 provides a 4x increase in productivity and throughput, all without the constraints associated with traditional laboratory testing. In addition, with a few extra seconds, further savings can be gained when bottles are pressure tested immediately following volume measurement. If the system is integrated with an automated sampling system, additional efficiencies can be realized. Furthermore, with automatic sampling, volume measurement can be staged throughout the day to occur between pressure testing jobs to maximize testing and take advantage of the efficiency of the system.
How it works
The volume measurement system incorporated in the SPT2 utilizes positive-displacement technology. In simple terms, the positive-displacement approach employed by the SPT2 works as follows; a known volume of fluid is transferred from a temperature compensated, calibrated piston and cylinder into the test container. At the same time, the fill level is dynamically monitored as the container is filled to overflow.
More specifically, the SPT2 incorporates a calibrated cylinder at the center of the volume station. During the volume measurement process, a piston pushes water from the calibrated cylinder into the bottle. A defined volume of water, relative to the container size and specifications, is dispensed into the container. The SPT2 measures the dispensed volume by tracking piston motion with a high resolution encoder. As the container fills, the level of the water meniscus is measured by a high resolution displacement sensor.
The positive-displacement method offers a number of advantages. Most significant is the accuracy. This filling technique, in tandem with a high-precision fill-height sensor makes it possible to deliver defined volume and fill measurements at any point within the process, to an accuracy of + 0.5 ml. This this is equivalent to a single drop of water! Other advantages include little or no effect on measurement precision due to water quality, container shape or rate of fill, regardless of the size and volume of the container. Furthermore, the volume measurement system on the SPT2 is self-contained, requires no delicate scales and is not affected by water density, flow rate, vibrations or issues that commonly plague other methods.
Non- round containers
Non-round containers present their own unique challenges when it comes to capacity. Non-round volume can vary dramatically as a result of subtle changes in the process. Heavy corners, sunken or bulged panels are some of the issues that can dramatically affect capacity and result in fill point and overflow volumes that are out of specification. With non-round containers, especially spirit bottles, managing capacity is critical. The SPT2 universal gripping system is able to handle a wide range of non-round shapes and sizes. Measurements are performed in the same manner as round bottles at the same levels of accuracy.
In addition to high precision volume measurement, Agr’s SPT2 also provides burst pressure testing. The pressure testing component of the SPT2, offers a solution to overworked testing laboratories and a need to maintain a continuous regimen of pressure testing 24/7. The SPT2 features an advanced, controlled-velocity pressure generation system that can pressurize containers up to 1000 psi (1 minute equivalent) while providing extremely accurate and controlled pressurization throughout the testing process. The system is designed specifically to meet industry testing requirements per ASTM C-147 and ISO 7458. The SPT2 incorporates a number of advanced features designed to simplify testing and improve plant efficiency. Some of the features include a high throughput rate of 270+ bottles per hour (when volume is not measured), a universal gripping system that can accommodate a range of bottle finishes up to 38mm and dynamic adjustment for bottles of varying diameter and height without job change. Jobs can be setup to perform proof or full burst tests, combined volume and pressure tests or just volume. Since the SPT2 can perform in-process job changes, it is possible to test bottles from different manufacturing lines, or hand-feed a set of bottles as required, with testing protocols unique to that specific bottle type, without the need to stop and reconfigure the system, maximizing testing efficiency.
Whether set up for pressure only or pressure and volume testing, the SPT2 can be configured as a stand-alone testing station, integrated into a sampling line in conjunction with a plant-wide process management system or combined with Agr’s OmniLab® automated measurement system. When combined with the OmniLab® system, pressure and volume as well as dimension, weight and thickness can be measured in a single hands-free operation with data correlated into one comprehensive report.

American Glass Research (AGR), in partnership with Molson Coors, has unveiled an innovative new beer bottle design for one of the brewing company’s popular brands in India, Thunderbolt. Featuring unique embossing and debossing, a fresh new color, and a ring-pull cap, the new bottle is designed to help Molson Coors distinguish Thunderbolt from other beers in the market.
Thunderbolt, described as “India’s original strong beer,” had previously been packaged in a 650ml amber bottle, a common bottle type in India’s returnable glass market. In an effort to have Thunderbolt’s packaging match its one-of-a-kind bold taste, Molson Coors turned to AGR to create a bottle that was proprietary, branded and uniquely recognizable in the marketplace, while remaining easy to produce.
“The collaboration with Molson Coors provided a unique challenge that we enthusiastically undertook,” said Bill Slusser, Manager of Research Services for AGR. “It is always gratifying when our customers provide such positive feedback regarding the introduction of a bottle design that is deemed a success both functionally and aesthetically.”
Produced in emerald green glass, the new Thunderbolt bottle features an instantly iconic debossed, shield-shaped label panel adorned with the familiar silver and blue paper label. The angular and aggressive shoulder construction displays an embossed lettering wrap that spells out the Thunderbolt brand name including a lightning emblem within the letter ‘O’. Two additional embossed lightning emblems bracket the back label panel, just above the lower sidewall pinch, which transitions into a prominent heel construction. A new ring-pull cap gives the bottle a modern and premium twist in both look and function.
“We have received rave reviews from both customers and consumers about the new Thunderbolt bottle, which we believe reinforces the brand’s identity of always staying original,” said Mr. Ashish Kapoor, President of Molson Coors in India. “Nobody can lay claim to our distinctively different, signature bottle, which in turn will bring greater savings and efficiencies to our business.”
The bottle was created by Dr. Wenke Hu and Brad Salitrik of AGR, using a concept design provided by Molson Coors. Harnessing their experience and knowledge of glass bottle design, Hu and Salitrik created an enhanced design incorporating the specific bottle features and characteristics specified by Molson Coors along with appropriate bottle thickness and glass distribution. Using Finite Element Analysis (FEA) techniques, the team was able to evaluate the bottle’s ability to acceptably withstand the expected loading conditions (internal pressure, impact and vertical load) and to verify that the bottle would perform as desired once it was manufactured.
