KPET High Barrier Film

Yongyuan is KPET High Barrier Film manufacturers and suppliers in China who can wholesale KPET High Barrier Film. PVDC coating film is also known as PVDC coating film, coating film, coating film, KPET High Barrier Film, referred to as K film, that is, KOP (including extinction KOP), KPET, KPA, KCPP, KCPE and other coating films.

PVDC resin is often used as composite materials or monomer materials and co-extruded film sheets. It is the most used high-barrier packaging material, and PVDC coated films are used in a particularly large amount. PVDC coated films use polypropylene (OPP), polyethylene terephthalate (PET), etc. as substrates. Since pure PVDC has a high softening temperature, is close to its decomposition temperature, and has poor compatibility with general plasticizers, it is difficult to thermoform and directly apply. Most of the PVDC films actually used are copolymers of vinylidene chloride (VDC) and vinyl chloride (VC), and films made of copolymers with methyl acrylate (HA) have particularly good barrier properties.

High-barrier film is a film with a multi-layer structure made by extruding a material with strong gas barrier properties and polyolefin with strong heat-sealing properties and moisture barrier properties at the same time.

Applications of KPET High Barrier Film:

A packaging product with better comprehensive barrier properties in plastic packaging products. It is not only different from acrylic emulsion, which has a sudden drop in tempering properties due to the increase in moisture absorption, nor is it different from nylon films, which have lower moisture barrier properties due to water absorption. Instead, it is a material with high barrier properties that is excellent in both moisture and gas barriers. It has the characteristics of flame resistance, corrosion resistance and good air tightness. Due to its strong polarity, it is insoluble in general solvents at room temperature. As a food preservation film, it is still popular until today. With the development of single-film composite, coating composite, casing film, and co-extrusion film technology, it is more widely used in military products, pharmaceuticals, and food packaging industries. Especially the quick-frozen and fresh-keeping packaging developed in large quantities with the modern packaging technology and the accelerated pace of modern people's life, the cooking utensil revolution of the microwave oven, and the extension of the shelf life of food and medicine.
