Packaging quality is of great importance in maintaining food and medicine quality. Even with controlled gas mixtures and high-barrier materials, gas composition inside packages can change over time, impacting product shelf life.
Test methods and instruments are designed to assess factors affecting gas composition:
Barrier Property: This test measures a material's resistance to gas permeation. Labthink permeation test series test high barrier material packages, providing a more accurate picture.
Air-tightness: Leakage can significantly compromise packaging. For soft packages, positive pressure methods (Labthink C660M Leak and Seal Strength Tester) inflate the package to identify weak points. Negative pressure methods create a vacuum to achieve the same goal (Labthink C660B Leak and Seal tester). Screw-top containers are tested for seal integrity between cap and bottle using similar instruments.
HeadSpace Gas Analysis: This test analyzes the gas composition in the empty space at the top of a package. It helps assess remaining gases after packaging and the release of adsorbed gases over time. Labthink C650M and C650H Headspace Gas Analyzer are developed for this purpose. Analyzing the gas concentration curve allows for a more comprehensive understanding.
