Definition Of Vacuum Bag And Precautions

Jul 03, 2017

     Vacuum bag, also known as personal moisture-proof bag, aluminum foil bag, aluminum-plastic composite bag, the material is generally Pet al Cpe or Pet Ny Al Cpe. The Pet--printing effect is good, Ny-S oxygen permeability is low, Al-S barrier is strong, opaque, Cpe packaging inner layer. Glue: Water soluble glue (more sanitary, environmental protection, no solvent residue) This product has a good anti-static, oxygen, shielding, moisture, shading function and excellent thermal seal. The process auxiliary material for curing forming of the vacuum bag thin film composite material can form and maintain a vacuum state under certain environmental conditions. Its function is to form a vacuum system.

     Whether fresh food or dry goods, vacuum compression bag to preserve the food is a good way to keep fresh. It is small, easy to use, economical and affordable, the biggest advantage is that it can be any bag into a vacuum compression bag to use. PE vacuum bag is different from PP vacuum bag. Polyethylene odorless, non-toxic, feel like wax, good low-temperature performance, PE vacuum bag minimum temperature can reach 200. Polyethylene chemical stability is good, can endure most acid-base erosion, at room temperature insoluble in the general solvents, water absorption is small, electrical insulation performance is good, but polyethylene thermal aging poor. Polypropylene has a high impact resistance, mechanical properties and strong, can resist a variety of organic solvents and acid-base corrosion.Vacuum Bag
     The bag has cracked or broken a small mouth can be used for common wide-edge Scotch tape on both sides of the stick, close together on it. Prevent too much water left in the bag, if a place temperature is relatively low, it will condense into water droplets. Vacuum Bag Classification Vacuum bag is generally divided into, Pa Pe or Pa Rcpp, Pet pe or Pet rcpp, in which the PE vacuum bag and PP vacuum bag is an important part of the vacuum bag products, the differences mainly include the following aspects. First, PE vacuum bag and PP vacuum bag chemical structure is different. PE, or polyethylene, is a simple structure of the polymer, by the repeated G-CH2-units connected, polyethylene is through the addition of ethylene polymerization. PP refers to polypropylene, a kind of semi crystalline thermoplastic.Vacuum Bag
