Kunshan nylon 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, non-toxic, tasteless, in line with national standards. Good sealing performance, transparency and good view of the current packaging machinery industry as a whole, less variety, backward technology, outdated equipment and poor reliability reasons for restricting the development of enterprises. So, a lot of packaging machinery companies began to try to replace the products, but many companies simply on the basis of the original equipment improvements, the lack of development and application of high-end technology. The rise of the packaging industry, need the help of high-tech, and enhance their competitiveness. Behind the rise is to strengthen the economic prospects for the future and optimistic about the market's confidence. Packaging industry has sprung up everywhere like state clearly beckons in the near future, it will become a sunrise industry for the better prospect.
