The Vacuum Bag Has Good Performance
Jul 26, 2017

Vacuum bag also known as intimate moisture bag, aluminum foil bag, aluminum-plastic composite bag, the material is generally PET/AL/CPE or PET/NY/AL/CPE, which pet--printing effect, ny--low oxygen permeability, al--barrier strong, opaque, cpe--packaging inner layer, glue: water soluble glue (more sanitary, environmental protection, no solvent residue) This product has good anti-static, oxygen, shielding, moisture, Vacuum Bags shading function and excellent thermal seal.

1. The vacuum bag has high temperature resistance (121 ℃), low temperature ( -50℃), oil resistance and good performance.

2, blocking air performance, oxidation, waterproof, moisture.

3, Vacuum bag non-toxic tasteless, in line with food, drug packaging hygiene standards.

4, strong mechanical properties, high blasting resistance, puncture and tear resistance.

The function and function of vacuum bag Now the use of vacuum bags has penetrated into various industries, whether in the supermarket or the market can be seen everywhere in the vacuum bag packaging food, although the use of a wide range, but the main aspect is food packaging, Vacuum Bags then what kind of vacuum bag function can be used in food packaging has a wide range of applications.

First, since it is called vacuum packaging bag, must be removed from the internal air, it is clear that oxygen is not there, we all know that food spoilage is mainly caused by microbial activities, without oxygen, then the microbial lack of survival of the environment, food nature can be long-term preservation.

Second, the vacuum can also prevent the oxidation of food, such as some lipids, Vacuum Bags to prevent its rancid, as well as vitamins such as, easy to change color, with a vacuum bag, can effectively maintain the color of food fragrance.

Third, the vacuum bag high barrier, has the effect of preventing water oxygen, the internal itself blocked these, plus this, with double protection, and stable performance, withstand the low temperature refrigeration, can endure the invasion of oil.

Four, some vacuum bags and moistureproof function, of course, Vacuum Bags there are no lack of heat-resistant, coupled with the traditional sterilization method, then food can be better preserved.

Vacuum bags are generally divided into

Pa/pe or Pa/rcpp.

Pet/pe or Pet/rcpp.

The PE vacuum bag and PP vacuum bag are the important parts in 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-ch2-units connected, Vacuum Bags polyethylene is through the addition of ethylene polymerization. PP refers to polypropylene, a kind of semi crystalline thermoplastic.

Second, PE vacuum bag and PP vacuum bag characteristics are different. Polyethylene odorless, non-toxic, feel like wax, good low-temperature performance, PE vacuum bag minimum temperature can reach -70~-100℃. Polyethylene chemical stability is good, can endure most acid-base erosion, Vacuum Bags at room temperature insoluble in the general solvents, water absorption is small, electrical insulation performance is good, but polyethylene thermal aging poor. Polypropylene has high impact resistance, strong mechanical properties, can resist a variety of organic solvents and acid-base corrosion
