What is the main purpose of hose cosmetics packaging? At present, there are many kinds of cosmetic packaging on the market, including plastic bottles, plastic boxes, plastic bags, plastic hose, etc. In recent years, with the rising popularity of cosmetic, plastic hose packaging with less raw material, the advantage of low cost rapid development, becoming the mainstream of the cosmetic packing market, mainly used in washing supplies, skin care and beauty products. Now that is commonly used in cosmetics packaging plastic hose are aluminum-plastic composite hoses, all plastic composite tube and plastic co-extrusion, tube can meet the diverse needs of cosmetics packaging. There is no doubt that the prime function of cosmetics packaging is to protect its contents. The main components of the cosmetics such as oil, water-soluble polymer and surfactant. As is known to all, glycerin and protein is the material basis for the microbes to grow, and oxygen and water are the influencing factors of microbial growth; Oil in the unsaturated bond easy oxidation, cause rancidity and metamorphism, produce the irritants such as hydrogen peroxide, acid, aldehyde, and issue a good smell. Thus, oxygen is the main factor of cosmetics metamorphic. Therefore, cosmetics hoses need excellent gas barrier performance, can effectively prevent the infiltration of oxygen and peculiar smell gas, prevent content, fragrance and effective components of leakage. It can be seen that the hose production after the completion of the whole pipe body permeability is not clearly defined. There is no need to test? The answer is no. Because cosmetics packaging overall sealing performance and the amount of oxygen through the tube directly affect the storage of the change of the original attribute of the cosmetics and toiletries, cosmetics hoses oxygen resistance detection is an index of relevant enterprises must pay attention to and control.
