US-based packaging products and services provider Agr International has unveiled a new packaging pressure tester for testing aluminium bottles.
The PPT3000 tester, which is part of the company's line of process monitoring and measurement products for the packaging and filling industries, is claimed to offer pressure and volume expansion testing capabilities for plastic containers.
The version features various testing routines designed specifically for testing light-weight, formed aluminium bottles and also cater to the needs of the companies filling aluminium bottles.
When performing pressure and expansion tests, the packaging pressure tester uses hydraulic (water) pressure as the testing medium.
Pressurising hydraulically affords various benefits, including the precise control of pressurisation, permitting complex loading curves as well as volume expansion measurement accurately, said Agr International.
According to the company, the PPT3000 test routines are capable to monitor volume expansion continuously as the aluminium container is pressurised, and capture pressure data at the exact moment when buckling occurs.
The PPT3000 test enables an operator to identify buckle point pressure, buckle point volume expansions and buckle volume expansion.
The operator can also set the initial loading pressure and duration as well as the ramp rate, and can monitor the test progress in real time through the PPT3000 display, claimed the company.
A comprehensive test report will be provided upon completion of each test, along with a test graph that displays the volume expansion and pressure where buckling occurred.
Pre-defined test profiles are provided with the tester to support the needs of both container manufacturers and fillers for quality control testing as well as improved package performance evaluation based on pressure, volume expansion or the material utilisation.
