"PEVA garment bags" i.e., polyethylene - vinyl acetate, EVA and PE is a blend of two synthetic materials, "PEVA garment bags" with good flexibility and little flexibility, wherein the higher the proportion of the PE, the adhesion the more intractable, generally used to produce the film. The ratio of these two chemicals is adjustable, thus in line with the different "" applications require higher levels of vinyl acetate, and its transparency, flexibility and toughness might raise.
