Also known as decompression vacuum packaging, is the main role of the vacuum bag is based on the principle that the atmospheric oxygen, in order to help prevent food spoilage or deterioration. Vacuum packaging is to food packaging bag and oxygen intracellular microorganisms deprived by pumping loss of "life" of the process. Nylon vacuum bag can prevent the oxidation of food, so the food does not taste deterioration reduce the loss of vitamins A and C. Product description: 1. air barrier performance, oxidation resistance, waterproof, moisture-proof. 2. High mechanical properties, high blasting performance, 3. high temperature (121 ℃), low temperature (-50 ℃), oil, incense guaranteed performance. 4. Non-toxic, tasteless, with food, pharmaceutical packaging hygiene standards. 5. sealing performance, flexibility, good barrier properties. Vacuum structure is generally: PET / PE or PET / CPP also have three, four, Shandong nylon material in order to increase the performance of nylon texture images, PET / PA / PE, PET / AL / CPP, PA / AL / CPP, PET / PA / AL / CPP vacuum packaging features: This product vacuum boiling (105 ℃), high barrier tightness, good heat sealing, environmental protection, longer shelf life. Usage: rice, peanuts, meat and meat products, fruits and vegetables. Excluding the packaging container local air (oxygen) can effectively prevent food spoilage transformation. Energy efficiency to prevent the exchange of packaging material content; using barrier (tightness) excellent packaging materials and sealing technology and strict requirements. To prevent food weight loss, loss of taste, but also to prevent secondary pollution. Accelerates the heat conduction. Transparent cryogenic vacuum: good low temperature performance characteristics of nylon can also be boiled 100 ℃. Suitable for frozen food packaging, and various chemicals, electronics and other products storage packaging. Material structure: PA15 / PE50, PA15 / PE60, PA15 / PE70 retort transparent bag: good performance in high visibility product features are built-in, can withstand 121 ℃, 4 分钟 high temperature sterilization. Is widely used in food preservation shelf packaging. Material structure: PA15 / CPP70, PA15 / CPP85 / PET12 / CPP70 Shandong nylon nylon _ _ provided by Weihai Weihai Fujingtang Fujingtang new decorative materials Limited.
