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
