Plastic Technologies creates permeation app for food, beverage packaging

Plastic Technologies Inc. (PTI) has launched a new free app that calculates the oxygen permeation of food and beverage packaging structures and containers.  The app, called PackLifeO2, is based on the M-Rule model and is available on iPhone/iPad and Android platforms.

Ron Puvak, director of business development and marketing for PTI, said in a news release that the company designed the app as a "back of envelope" calculator for specific materials and combinations.

The company said the PackLifeO2 calculator is an ideal tool for packaging professionals, plastic processors, resin producers, lab techs, plant production, equipment manufacturers and others involved in the package selection process. 

The app consists of five input sections, material, layers, concentration, conditions and results, which are designed help the user quickly input data and obtain oxygen permeation results for their specific container.

PTI says the first screen asks the user to identify the packaging dimensions, surface area and capacity. Next, variables for material and thickness are entered, and up to three layers can be used for the calculation. The user selects the material options from a pull down menu, which include polyethylene terephthalate, low-density polyethylene, polypropylene, polycarbonate and nylon 6. Each layer's thickness in centimeters is also input.

The next screen asks for input of initial internal and external oxygen concentration at weight per volume parts per million. This is followed by temperature (relative humidity is preset at 50%) and time (number of days) over which the oxygen permeation should be calculated.

With those inputs in place, the user clicks on "graph" to pull up the next screen, which displays what happens to the parts per million of internal oxygen as the package is virtually subjected to the predetermined test period.  There is also a follow-up screen that displays a summary of the input variables.

This app is located in the iTunes App Store or the Android Play Store by searching for "PackLifeO2."
