Influence of Layer Thickness on Barrier Properties of Composite Films-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Influence of Layer Thickness on Barrier Properties of Composite Films This study investigates the effect of increasing single-layer thickness in composite films on their oxygen barrier properties for packaging applications. Increasing film thickness generally improves barrier properties, but also raises packaging costs. Composite materials with different single-layer films can optimize barrier performance. Blindly increasing thickness may not be costeffective. The study tested oxygen transmission rate (OTR) of PET (polyethylene terephthalate)/PE (polyethylene) films with varying layer thicknesses. The experiment adopted the test methods stipulates in ASTM D1434, and the testing instrument is Labthink VAC-V2 Gas Permeability Tester.

Influence of Layer Thickness on Barrier Properties of Composite Films-2

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 The thickness of the films can be measured by Labthink C640 Thickness Tester. The test result showed that increasing thickness of either PET or PE layer decreased OTR. Thicker PET layer (specimen #3) showed a more significant reduction in OTR compared to thicker PE layer (specimen #2). In conclusion, PET layer plays a dominant role in oxygen barrier properties for these materials. Increasing PET layer thickness is more effective in improving oxygen barrier performance.
