How to choose packing solution for case---stretch wrapping machine

Vacuum packing is the main function of oxygen in order to prevent food spoilage, its principle is simple.Because food metamorphism causing mold mainly caused by the activity of microorganism. And the survival of most microorganisms (e.g., mold and yeast) is need oxygen, and vacuum packing is using this principle. The packaging and food within the cell oxygen smoke, lose microbial survival environment. Vacuum deaeration besides inhibiting microbial growth and reproduction, another important function is to prevent the oxidation of the food, because the oil kind food contains a lot of unsaturated fatty acid, by the effect of oxygen oxidation, sour food, deterioration. To have the effect such as compressive strength, the air resistance, the fresh, can more effectively and make the food for a long time to keep the original color, aroma, taste, shape, and nutritional value. When the choose and buy, the packing solid, grain, dry and no corrosive materials such as aluminum alloy material, optional and packing with broth, salt, high acid ingredients of the material, can choose stainless steel or aluminum magnesium alloy material. Seal generally adopt silicon rubber, black rubber, a handful of low-grade products adopt foam rubber, silicone rubber high temperature resistance, corrosion resistance, good sealing, long service life, foam rubber seal is poor, easy to fall off, short service life. And vacuum sealing machine in the process of using, though for a variety of food, meat products, seafood, fruit and vegetable, pickles, chilled meat, phaCoil-packaging-machine-and-stretch-wrapper-2014-05-17.htmlrmaceutical products, hardware components, medical devices etc for pumping air into vacuum state, inflatable,. But, in essence, or more than two devices, there still have very big difference. Vacuum sealing machine products mainly isolated from any air contacted with the outside world. And vacuum packaging machine, for the tea in the practical application of intermediate. It mostly adopts the system of microbial, prevent the oxidation of the food in a way that use. In addition, different products, there're effect of different existence. It is well known. Therefore, the equipment in the process of purchasing, please be sure to pay attention this problem.
