Through deoxidation, the shelf life of corrosive products can be prolonged. The simplest is to put the product into the bag and empty the air. However, due to the influence of environmental pressure on the shape of the product, it may greatly change the shape of the product.

For this reason, the map program has become a choice in many areas. In this procedure, the product is packaged in a correction gas and oxygen is removed. The products are packed with blisters, placed in a vacuum chamber, and the air is evacuated. Then, the correction gas is injected and the blister package is sealed by a protective film. In this way, even if the storage is delayed, the food will keep its original shape and the meat will keep its corresponding red color.

 

PET container production

Although the production of PET bottles is part of the packaging industry, the process is the same as that of the plastics industry. (vacuum pump) the application of vacuum pump is as follows: drying and conveying of plastic particles; degassing of extruder; injection molding; film removal and treatment and drying of injection parts; bottle blow molding and pneumatic conveying; plasma treatment to set isolation layer; filling, filling and labeling; packaging, molding and recycling.
