EVA plastic film, the full name of butadiene-vinyl acetate polymer, is a soft and transparent plastic film, which is mainly used for packaging products, building decoration materials, protective films for electronic equipment, solar cell packaging films, etc. [1][2]. Compared to other materials, EVA plastic films have the following advantages:
1.Breathability and moisture permeability: EVA plastic film has good air permeability and moisture permeability, which can be used to make breathable packaging products.
2.Chemical Resistance and Aging Resistance: EVA plastic film has good chemical resistance and aging resistance, and can resist harmful substances in the natural environment to a certain extent.
3.Good tensile strength, tensile strength, flexibility, impact resistance, electron-optical openness and adhesion: EVA film has good tensile strength, tensile strength, flexibility, impact resistance, electron-optical openness and adhesion.
4.Flexibility and flexibility: EVA plastic film has good flexibility, folded friction, easy transportation, and at the same time, it has a certain elasticity, which can resist external pressure and impact to a certain extent, and maintain packaged food.
5.Better electro-optical clarity: EVA plastic film has good electro-optical clarity and can pass through most light sources to make the packaging design clearly visible.
6.Low temperature resistance: EVA plastic film can still maintain good flexibility and flexibility in low temperature environment, and is suitable for product packaging used in severe cold environments.
7.Adhesion: EVA plastic film has a certain adhesion and can be bonded with other raw materials to produce a composite material and improve packaging maintenance characteristics.
Generally speaking, the advantages of EVA plastic films lie in their good process properties, such as flexibility, elasticity, clarity, chemical resistance and temperature resistance, and thus have broad application prospects in many fields.
