Main products: aluminum foil bag, vacuum bag, shielding bags, aluminum bags, board vacuum bags, cooking food vacuum bag, nylon vacuum bag, anti-static bags and other packaging materials, metal. A vacuum bag, bags are generally complex, that one, two or more of the basement membrane (sealing PE film, CPP, BOPP) and nylon (airtight better) or PET film special glue bonding by Franciscan (chemical products) through complex machine composite film. Then by cutting bag machine made, after vacuum sealing performance is optimal. Air barrier performance, oxidation, waterproof, moisture and strong mechanical properties, good anti-puncture performance. Mainly used for packaging food, such as meat, cereals and processed foods easily oxidative deterioration of food, can also be used for mechanical parts, instruments and feather products, hair products and other fluffy product packaging. The material is generally NY / CPE or PET / NY / CPE. Once the product has a good anti-static function, the vacuum effect is good, high transparency, transparent (oxygen) gas is low, moisture resistance, high tensile strength and puncture resistance degree easy to seal, sealing, and not aging characteristics. Mainly used for hardware, electronic components, require vacuum packaging requirements. The main material of the vacuum bag: one in which the PE for low temperature use, RCPP suitable for high temperature cooking so; two, PA is to increase physical strength, puncture resistance; three, AL foil in order to increase the barrier properties, shading; four, PET increased mechanical strength, stiffness of distinctions. Then according to demand, in combination. Several types of vacuum complex: generally: PA / PE or PA / RCPP PET / PE or PET / RCPP have three, four of. In order to increase the texture of the material properties of the composite can also do the following: PET / PA / PE PET / AL / RCPP PA / AL / RCPP PET / PA / AL / RCPP Features: 1, high barrier: the use of high barrier properties of materials co-extruded film, to oxygen, water, carbon dioxide, odor barrier effect; 2, stable performance: oil resistance, moisture resistance, low temperature freezer, shelf, preservation, security odor, can be used for vacuum packaging, aseptic packaging, inflatable packaging; 3, low cost : Relative glass packaging, aluminum foil, and other plastic packaging, co-extruded film has a large advantage in terms of cost; 4, high strength: co-extruded film having a tensile characteristics in the process, may also be added in the middle of nylon, polyethylene vinyl and other materials, it has more than ordinary plastic packaging composite strength. With anti-static, anti-electromagnetic interference, moisture three functions. Sealing firm, strong ability between the layers of composite material: four-layer structure, has a good waterproof, oxygen barrier function: puncture resistance. Try to have a moisture-proof packaging requirements for electronic products: all kinds of PV panels, IC integrated circuits, optical drives, and other electronic components.
