- Nov 15, 2018 -

When the plastic packaging film is operated, the polyester film is mainly made of polyethylene terephthalate, and is mainly a film material which is formed into a thick sheet by extrusion and then biaxially stretched. It is a colorless, transparent and lustrous film with excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high temperature and low temperature resistance, chemical resistance, oil resistance, good air tightness and aroma retention. It is one of the commonly used barrier composite film substrates.

 

The plastic packaging film is a very tough film. It has good transparency and good gloss when used. The whole product has good gloss, tensile strength, high tensile strength and good heat resistance. , cold resistance, oil resistance and organic solvent resistance, excellent wear resistance and puncture resistance, and relatively soft, excellent oxygen barrier, but poor barrier to water vapor, moisture absorption, moisture permeability, heat sealing Poor, suitable for packaging hard items, such as greasy food, meat products, fried foods, vacuum-packed foods, cooked foods, etc.

 

The plastic packaging film has excellent transparency and uniform thickness, and uniform performance in the longitudinal and lateral directions, and is generally used as an inner layer material of the composite film. The thickness of ordinary CPP film is generally between 25and 50μm. After compounding with OPP, the transparency is good, the surface is bright, and the hand feel is firm. The general gift packaging bag uses this material. This film also has good heat sealability.http://www.xmlfilm.com/
