Popularity:5820Publication time:2018-7-11
EVA products can be seen everywhere in our lives, such as the lining for packaging products, as well as soundproof cotton, and may also be used to make ground materials. EVA products have many advantages, but some people have found that some EVA products will fade, but some will not. Why? EVA packaging box lining manufacturers give you a brief introduction:
1. this has a great relationship with colorants. If some colorants are highly reducible, they will affect heat resistance and fade.
2. some organic pigments react with other chemicals.
3. the heat resistance of pigment selected during processing is less than the heat resistance of EVA products.
4. colorants are not light enough. Light resistant colorants are easily affected by strong light.
