What is the difference between PEVA film and EVA film?

PEVA film and EVA film are both types of plastic film, but there are some differences between them. First of all, PEVA film is a polyethylene-vinyl alcohol copolymer, while EVA film is an ethylene-vinyl acetate copolymer. Because PEVA film contains vinyl alcohol, it has good water solubility and biodegradability, which makes it widely used in the field of environmental protection. At the same time, PEVA film has relatively good softness and transparency, and is often used to make products such as handbags and tablecloths.

In contrast, EVA film is known for its good elasticity and flexibility. It has excellent low-temperature resistance, so it is often used to make cold-proof clothing, shoe materials, etc. EVA film also has good chemical stability and anti-aging properties, and is suitable for use in various packaging materials and cushioning materials.

In general, PEVA film and EVA film have their own characteristics and are suitable for different application scenarios. The choice of which material to use needs to be determined based on specific product requirements and performance needs.
