What are cosmetics hose resistance performance test oxygen hose
Cosmetics hoses have plastic bottles, plastic boxes, plastic bags, plastic hose, etc. In recent years, with the increasingly common cosmetics, packaging with the raw material used to rapid development, as well as advantages of small, low cost and is now the mainstream of the cosmetic packing market, mainly used in cleansing products, skin care products and beauty salon products.

Thus the oxygen is the most important factor of cosmetics metamorphic. Cosmetics hoses need has excellent gas barrier performance, can effectively prevent the infiltration of oxygen and peculiar smell gas, at the same time prevent the content fragrance and effective ingredients. Can be seen that this standard is just on the sheet of oxygen permeability testing regulation, the hose is made after the whole pipe body oxygen permeability is not that clear. Is that there is no need for detection, the answer is no. For cosmetic packing sealing performance of the whole and the tube body oxygen through directly affects the amount of the storage life of cosmetics and the change of original nature cosmetics, cosmetics hose resistance performance test of oxygen is related enterprises must pay attention to and control index.
