PVC garden hose is favored by pipeline engineering because of its light weight, corrosion resistance, low water loss and convenient installation. At the same time, compared with traditional metal pipes, plastic pipes have less energy consumption (generally less than 1:4) and less environmental pollution, which are increasingly valued by the government and relevant departments.
1. Exclude some air (oxygen) in the packaging container, which can effectively prevent food spoilage.
2. The use of good barrier (air tightness) packaging materials and strict sealing technology and requirements can effectively prevent the exchange of packaging contents, which can avoid food weight loss, odor loss and secondary pollution.
3. The gas inside the hose container of cosmetics has been eliminated, which accelerates the heat transfer. This can improve the efficiency of heat sterilization and avoid the cracking of packaging container due to the expansion of gas when heating sterilization.
