Kunshan rice vacuum

Vacuum-packed bags of rice, whole grains vacuum, vacuum nylon 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 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. Physical characteristics and standards: Item Unit Index value distinction reference standard tensile strength Mpa MD / TD 220 * 310 ASTM-D882 Elongation% MD / TD 125 * 72 ASTM-D882 30 minutes to be oxygen by volume cc / m day 20 ~ 40 ASTM-D3985 water vapor permeation rate g / m day 510 * 557 ASTM-B95 Description: those due to different measurement and measurement instrument, the data may be different, (measurement conditions: 23 ℃, 50% RH) TD: Portrait MD: transverse product mainly applicable to all types of PC boards, IC integrated circuits, optical drives, hard drives, LCD monitors electronic components, various types of food, such as vacuum packaging. Specifications: Size can be customized scope of products and industrial products industries according to customer demand: welding materials, electronic products, circuit boards and other vacuum food packaging: rice, meat products, dried fish, aquatic products, sausages, roast duck, chicken, roast pork, frozen food, ham, bacon products, sausages, cooked meats, pickles, red bean paste, spices and other packaging machinery industry as a whole in the current term, fewer species, backward technology, outdated equipment and poor reliability reasons restricting the development of enterprises.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.
