Characteristics and classification of EVA bag and EVA cases

EVA is a plastic material composed of ethylene (E) and vinyl acetate (VA). The ratio of these two chemicals can be adjusted to meet different application needs. The higher the content of vinyl acetate (VA content), the transparency, softness and toughness will be relatively improved.EVA hard shell Backpack02
