What are the features of EVA lining in the first time?

Popularity:3150Publication time:2018-4-26
EVA lining is a new type of environmental protection packaging material made of EVA material. EVA has the advantages of fireproof, waterproof, shock proof, easy to process, and is also a new type of packaging material that can be formed at the same time. The advantages of the EVA liner's forming at once make it very popular. Today I want to talk about the characteristics of EVA forming once.
1.EVA is a closed cellular structure material without water absorption, moisture resistance and good water resistance.
2.EVA can resist corrosion and resist chemical corrosion. It is a product without poison and antibacterial.
3.EVA inner lining is easy to form and process, no joint, and can be processed by hot pressing, tailoring, gluing and laminating.
The 4.EVA liner can ensure the temperature of the product at one time, and it can also guarantee its performance in extremely high temperature or extremely cold places.
5.EVA once forming can have sound insulation effect, because EVA belongs to the closed bubble hole, so the sound can be absorbed, the sound insulation effect is very good.
