At present, the packaging of cosmetic hoses on the market can be described as various, and only plastic bottles, plastic boxes, plastic bags, plastic hoses and the like are available. In recent years, with the increasing popularity of cosmetics, cosmetic plastic hose packaging has been rapidly developed due to its low raw material use and low cost. It has occupied the mainstream of the cosmetics packaging market, mainly used in cleansing products, skin care products and beauty salon products. .

The main components of cosmetics are oils and fats, water-soluble polymer compounds, surfactants, and the like. It is well known that glycerin, protein and so on are the material basis for the growth and reproduction of microorganisms, while oxygen and water are the factors that affect the growth of microorganisms; the unsaturated bonds in oils and fats are easily oxidized to cause rancidity and deterioration, and at the same time produce peroxides, acids and aldehydes. Equal irritating substances and give off rancid odor. It can be seen that oxygen is the most important factor causing cosmetic deterioration. Therefore, the cosmetic hose needs to have excellent gas barrier properties, can effectively prevent the infiltration of oxygen and odor gas, and prevent the fragrance of the contents and the exudation of the active ingredients.
