Plastic hose has good development superiority and the physical and chemical properties

Plastic hose has good development advantages and physical and chemical properties of plastic hose is convenient to use, economic health, has become a one of the main varieties of packaging of cosmetics, medicines, food. Since the 1990 s, China imported from Europe, America, Japan and Taiwan area has a large number of advanced composite hose production equipment, strong momentum. Multilayer, thin, transparent plastic composite hose is the development trend of the future. Cosmetic, medicine and food, the first thing to consider is the health performance, followed by mechanical strength, barrier properties, printing adaptability and chemical resistance. Of course, we must also consider the use of efficiency and convenience. Using a good barrier property ( Good air tightness) Packing materials and sealing technology and strict requirements, can effectively prevent the package content in the exchange of material, as to avoid the effect of weight loss, loss of contents and secondary pollution. 。 Oxygen is the main factor of cosmetics rancidity. Most cosmetics contain oils. Oil in the unsaturated bond oxidized easily, cause metamorphism and rancidity. As long as there is a small part of the unsaturated oil oxidation, will lead to oil rancidity completely, reduce the quality of the product. Therefore, in the production, storage and use of cosmetics, should try to avoid the happening of rancidity, prevent oxygen to enter. In general, plastic hose has the incomparable advantages to other materials. Therefore, since birth, it will appear in the cosmetics and pharmaceutical packaging. At present, it has become indispensable to cosmetics, pharmaceutical packaging.
