How to embody the barrier performance of PE plastic bottle

PE plastic bottle is polyethylene plastic bottle. Its barrier performance is mainly reflected in the barrier ability to gas, water vapor and some solutes. The following is a detailed introduction: 1. gas barrier Principle: the molecular structure of PE plastic bottle is relatively compact and has a certain degree of crystallinity. The presence of crystalline regions makes it difficult for

How to demonstrate the barrier performance of PP cream jar

The barrier performance of PP cream cans is mainly reflected in their ability to block substances such as oxygen, water vapor, and light, as follows: 1. Oxygen barrier Stable molecular structure: PP has a tight molecular structure and high crystallinity, making it difficult for gas molecules to penetrate its molecular gaps. When oxygen molecules attempt to pass through the PP tank wall, t
