EVA has a wide range of applications in our daily production and life, specifically: anti-static EVA, high-elastic EVA, odorless EVA and other products. It is even more puzzling for people who are not professionals in this area in our daily life.
What is EVA? How is it different from ordinary foam? Why do manufacturers like to use EVA materials so much? The reason is that EVA material has many advantages that are unparalleled by other materials.
EVA, also known as ethylene-vinyl acetate copolymer material, is a new type of environmentally friendly plastic foam material. EVA material products are generally well-made and have the advantages of good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and are non-toxic, non-absorbent and have a soft surface. The tensile toughness is stronger than that of LDPE and it feels sticky but has no glue on the surface). It is white, transparent, has high transparency, and its appearance and feel are very similar to PVC films. Pay attention to the distinction. EVA foam materials have good economic benefits, especially for injection once cross-linked hair. Foam molding and in-mold foam molding technology have the advantages of industrial continuity, short production cycle and saving of raw materials.
1. Biodegradable: It will not cause harm to the environment when discarded or burned.
2. Similar price to PVC: EVA is more expensive than toxic PVC, but cheaper than phthalate-free PVC.
3. Lighter weight: The density of EVA ranges from 0.91 to 0.93, while that of PVC is 1.32.
4. No odor: EVA does not contain ammonia or other organic odors.
5. Does not contain heavy metals: complies with relevant international toy regulations (EN-71 Part 3 and ASTM-F963).
6. Phthalate-free: suitable for children's toys and will not cause the risk of plasticizer release.
7. High transparency, softness and toughness: the application range is very broad.
8. Super low temperature resistance (-70C): suitable for freezing environments.
9. Resistant to water, salt and other substances: it can remain stable under a large number of applications.
Based on the above advantages, I believe everyone has a general understanding of the advantages of EVA packaging materials.
