The main features of vacuum packaging bags are vacuum packaging, good sealing effect, not easy to break the bag and leak air, use the principle of atmospheric pressure to pump air and deoxygenate, play a good role in anti-fouling, moisture-proof, prolonging the shelf life and keeping fresh, making it a good packaging material. The best of the bag.The vacuum packaging bags produced by Hebei Jiuyue Plastic Industry are mainly aluminum foil vacuum bags and nylon vacuum packaging bags. Medical, electronic and other fields. Let’s talk about the difference between these two vacuum packaging bags:Aluminum foil vacuum packaging bag: Aluminum foil vacuum packaging bag is generally composed of three layers of materials or four layers of materials:PET/AL/CPE,PET/AL/NY(PA)/CPEIt has good functions of waterproof, oxygen barrier and light protection. The aluminum foil vacuum packaging bag is characterized by opacity. The bag type can be customized as self-sealing zipper bag, self-supporting zipper bag, envelope self-adhesive type, one-piece type, three-dimensional type, etc. according to customer requirements. Generally, relevant colorful patterns can also be customized according to customer requirements. Internal and external surface resistance value:10^9—10^11Ω.Nylon vacuum packaging bag is also called decompression packaging, which is to extract all the air in the packaging container and seal it to maintain a high degree of decompression in the bag. The scarcity of air is equivalent to the effect of low oxygen, so that microorganisms have no living conditions, so as to achieve fresh fruit. The purpose of rot. Nylon vacuum packaging bags generally have two or three layers of materials:NY/CPE,PET/NY/CPE. It has good anti-static function, vacuum effect, moisture-proof and other functions. The same specifications can also be customized according to its customers.Food Vacuum Bag Product Description :1.Strong air barrier performance, anti-oxidation, waterproof and moisture-proof.2.Strong mechanical properties, high blast resistance, strong puncture and tear resistance.3.High temperature resistant(121℃), low temperature resistance(-50℃), oil resistance, good fragrance performance.4.Good heat sealing performance, softness and high barrier performance.
