About the role of vacuum packaging

Vacuum packaging machine technology originated in the 1940 s. In 1950, polyester, polyethylene plastic film successfully used in vacuum packaging, since then, vacuum packaging and got rapid development. China's vacuum packing technology is developed in the early 1980 s, and vacuum packaging technology in the early 1990 s began to use small amounts, along with the development of the small package promotion and supermarkets, its scope of application is more and more widely, some will gradually replace the rigid package, the future is very promising. Vacuum packing machine is the main function of oxygen, is beneficial to prevent food spoilage, its principle is simple, because food metamorphism causing mold mainly caused by the activity of microorganism, and most microorganisms ( Such as mold and yeast) Survival is need oxygen, and vacuum packing is using this principle, the packaging and food within the cell oxygen smoke, lose microbial survival environment. Vacuum packing machine to vacuum packaging of products, mainly adopts the vacuum membrane, for vacuum packaging film, the quality is critical, want to choose good. To adopt quality qualification and has the thickness of the vacuum packaging film, and in front of the device packaging and use of membrane process, are intended to ensure that it does not damage caused by the leakage. Vacuum packaging machine drive system used in although application function is simpler, but have higher demand to dynamic performance of drive system for faster dynamic with high performance and steady speed precision. So must consider the dynamic frequency converter technology index, choose high performance inverter can meet the requirements. Vacuum packing machine is combination according to the manufacturer has been widely applied in packaging industry packaging equipment, one of the vacuum packing equipment compared with traditional packing machinery failure happens rarely, but due to the high degree of automation, could cause a machine fault, because the error caused by normal packing, and vacuum packaging machine maintenance cost is higher, learn to solve common glitch in production, is very necessary, so as not to affect the production plan because of the small problems.
