Characteristics and application fields of PET pre-coating film
Author:
The full name of polyester is poly-ethylene glycol ester with high mechanical strength, high stiffness, impact resistance, good physical stability, heat resistance, oil resistance, good drug resistance, and corrosion resistance. It is resistant to organic solvents and resins. It has certain chemical resistance when it is not in contact with strong alkali. At the same time, polyester has high transparency and good gloss. Polyester film also has good gas barrier properties and good printing performance.
PET pre-coating film (polyester pre-coating film) is a laminated composite film formed by PET film (polyester film) and EVA hot melt adhesive. It has the characteristics of PET film and excellent composite properties.
PET pre coating film features:
1, has good light resistance, good physical stability;
2, waterproof, antifouling, wear resistance, chemical corrosion resistance, with a certain barrier;
3, smooth, high transparency, good stiffness;
4, environmental protection and safety, non-toxic, tasteless, no benzene, no foaming and stripping phenomenon during the film coating process;
5, can adapt to the rapid production of machinery;
6, wide applicability, can adapt to all kinds of paper products, imitation paper materials after printing plastic packaging.
Application fields of PET pre-coating film:
Used in food flexible packaging, gold and silver cardboard, high-grade wine boxes, cosmetics packaging, medicine boxes, gift boxes and books and magazines cover, advertising products coated industries. At the same time, because of its good printing performance, it can be combined with cardboard or non-woven fabric, and applied to heat insulation pad, flower packaging film, color composite card, etc.
