Suzhou vacuum bags are generally complex, that is one, two or more of the basement membrane (sealing PE film, CPP, BOPP) and nylon (airtight better) or PET film special glue bonding by Ji (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 blasting performance, strong anti-puncture tear resistance, high temperature (121 ℃), low temperature (-50 ℃). Non-toxic, tasteless line with national standards. Good sealing performance, good transparency. Mainly applicable to all types of PC boards, IC integrated circuits, optical drives, hard drives, electronic components and other packaging. Plastic packaging lightweight, lightweight and now has become a major trend in the packaging industry, less production of packaging materials, packaging makes weight loss much lower cost to the environment and businesses are profitable, generally speaking, Plastic bottles, plastic containers, plastic hoses and plastic covers and other types of containers easier to achieve weight loss goals. As people's living environment and the continuous improvement of environmental quality, green, environmentally friendly, low carbon plastic packaging will be more respected by the people. Plastic packaging has been further developed mainly to food packaging to industrial packaging, pharmaceutical packaging, building materials packaging, cosmetic packaging and other fields, and its scope and prospects will be more broad.
