High Quality Biodegradable PLA Coated Paper Printing Paper Raw Material Roll for Tea Cup

Both PLA - coated and PE - coated films have certain oil - resistant properties, but there are some differences between them.

PLA - coated films

PLA has good initial oil resistance. However, its oil - resistant performance may decline under high - temperature and high - humidity conditions. This is because PLA is a biodegradable material, and its molecular structure is more easily affected by the environment. For example, when in contact with oil - containing substances for a long time at high temperatures, the ester bonds in the PLA molecular chain may be hydrolyzed, reducing its oil - resistant ability.

PE - coated films

PE - coated films have excellent oil resistance. PE is a non - polar polymer, and its molecular structure is relatively stable. It has strong resistance to oil penetration and can maintain good oil - resistant performance under a variety of conditions. Whether it is at normal temperature or under high - temperature conditions, PE - coated films can effectively prevent oil from penetrating the paper substrate, thus protecting the quality and performance of paper products.

Eco - friendliness. PLA, a biodegradable material, significantly reduces environmental impact by decomposing naturally, unlike non - biodegradable PE.
