Conclusion: Write based on your objectives
Materials and Methods 1. Listen to a lecture about Microbiological Integrity Testing Chamber for integrity testing of 2L paper/plastic laminated aseptic brik pack. 2. Aseptic package integrity a. Electrolytic package test a nd ink test was performed on a half of an aseptic brik pack to find carton with pinhole b. ARO-Test-A-Pak vacuum bubble tester was used to test the integrity of an aseptic brik pack and a snack bag. c. Carleton Test-A-Pak was used to test a snack bag and an aseptic thermoformed package. The burst and creep test was performed on a snack bag and the creep test was performed on an aseptic thermoformed package. d. An aseptic brik pack was ripped down according to the instruction provided in the laboratory handout.
