EVA, also known as ethylene-vinyl acetate copolymer material, is a new type of environmental friendly plastic foaming material. EVA material products are generally well-made, with good cushioning, shock-proof, heat insulation, moisture-proof, chemical corrosion resistance and other advantages, and the surface is non-toxic, non-absorbent and soft. Tensile toughness is stronger than low density polyethylene, but the surface is not bonded. White transparent, high sensitivity, handle similar to PVC film. It should be distinguished. Eva foaming material has good economic benefits, especially the single cross-linking foaming technology has the advantages of industrial continuity, short production cycle and saving raw materials.

So EVA material is usually used in the lining.
