The Agr International Packaging Pressure Tester PPT3 (Model: PPT3 / PPT3000™) is 100% designed, engineered, and manufactured in the United States by Agr International, Inc. – the internationally acclaimed authority in container quality assurance, dimensional metrology, and physical strength testing instrumentation. Serving as a crucial process tool for PET container production, the PPT3 enables plastic converters and major beverage brands to optimize container material distribution and execute lightweighting initiatives while safeguarding container structural performance under actual filling and shelf-life distribution pressures.

The defining competitive strength of the Agr PPT3 resides in its high-resolution, closed-loop servo-controlled pressure generation and temperature-compensated volume expansion measurement system. The instrument features Agr’s proprietary, patent-protected Fill-Ramp™ test mode, specifically engineered to simulate the rigorous conditions of carbonated soft drink (CSD) filling lines. In this mode, the container is rapidly pressurized to an operator-specified threshold, held for 13 seconds, and then ramped linearly at a rate of 10 psi per second until failure or maximum limits are reached. This testing routine provides direct correlation between volume expansion and critical field parameters, including bottle creep, CO2 permeation, stress cracking, wall rigidity, topload capacity, and bottom roll-out prevention.

In addition to the Fill-Ramp™ protocol, the PPT3 provides comprehensive testing versatility, including rapid linear ramp-to-burst testing, pressure-hold creep evaluations, and optional M-RULE® shelf-life simulation modules that predict container O2 and CO2 retention over time. The instrument accommodates internal pressures up to 300 psi (20.7 bar) and captures volume expansion up to 1.85 liters. Engineered with a durable composite exterior and corrosion-resistant stainless steel internal mechanics, the testing chamber features a mechanical-electrical interlocked safety door that isolates high-velocity water and debris during container burst events. Fitted with an intuitive color touchscreen HMI and dual Serial/Ethernet digital communications, the Agr PPT3 stands as an essential quality control instrument across high-speed blowmolding facilities and beverage packaging laboratories worldwide.
