what is the stability of eva film?

1. eva film has high chemical stability, and eva film bags have good plasticity. except for a few organic solvents, the eva film can withstand any concentration of hydrochloric acid, less than 90% sulfuric acid, 50-60% nitric acid and less than 20% caustic soda at normal temperature. it is also quite stable against salts; pvc thermal stability and light resistance are poor. eva film and eva packaging bags can begin to decompose and release hydrogen chloride (hcl) gas above 140°c, causing pvc to change color.

2. non-toxic, pollution-free, recyclable, decomposable, does not produce poisonous gas when burned, does not pollute the atmosphere, and is a green and environmentally friendly material;

4. light in weight, with a specific gravity of about 0.9, it can replace pvc exported products;

5. it feels good, smooth, soft and easy to process, and can be printed, voltage, ultrasonic processed, sewn, etc.;

6. there is no significant difference in performance between seasons, and it is resistant to low temperatures, with the material being able to withstand temperatures as low as -70℃~-35℃;

7. product specifications: film thickness is 0.06mm-1.0mm, width is up to 2.3m, and a variety of embossing options are available;

8. can produce: transparent, translucent, frosted, 3d, mirror, two-color, diamond, imitation cloth and other textures. kunshan zhifeng plastic packaging products co., ltd. can also customize various special textures for customers. the colors are diverse and rich, and can be matched and chosen at will;

9. strong adhesion to other materials, such as lamination with various fabrics, non-woven fabrics, mesh, etc., for making luggage fabrics and other waterproof and moisture-proof fabrics

10. various additives can be added according to needs to make films for special purposes, such as anti-mildew and anti-bacterial, anti-ultraviolet, anti-static, etc.
