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. Principles generally nylon vacuum bag vacuum bag, 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, high performance, strong anti-puncture tear resistance, high temperature (121 ℃), low temperature (-50 ℃). Non-toxic, tasteless line with national standards. Good sealing performance, good transparency. Scope mainly applicable to all types of PC boards, IC integrated circuits, optical drives, hard drives, electronic components, a variety of food, bacon, sausage, ham, etc. vacuum packaging.
