Cosmetic plastic hose in the application of cosmetics and pharmaceutical packaging

Cosmetic plastic hose application in cosmetics and pharmaceutical packaging cosmetics, 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. Compared with other products packaging, cosmetic plastic hose for resistance to water and oxygen resistance have higher requirements. On the one hand, water containing fat may contain mould and yeast, they can produce fat oxidation, fat hydrolysis, oxidation into fatty acids and glycerol. In addition, some powder products in order to prevent moisture absorption to agglomerate, hardening and metamorphism, so a lot of cosmetics packaging requires blocking access to water. On the other hand, some products containing water is used to clean the skin. Therefore, it is necessary to maintain moisture content within a certain amount of time. Therefore, it is necessary to prevent water escape. 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. Since birth, it will appear in the cosmetics and pharmaceutical packaging. At present, it has become indispensable to cosmetics, pharmaceutical packaging. Plastic hose according to the material classification can be divided into multiple single hose and hose. Single hose including metal hose and plastic extrusion hose; Multilayer hose including lu: su composite hose, plastic composite hose and plastic co-extrusion hose. Plastic hose can be classified into seamless tube, and slotted tube. Most of China's large-scale manufacturer of plastic hose has introduced world-class advanced production equipment, such as the Swiss KMK, Aisa high-speed pipe-maling machine; The United States, Japan and Taiwan region of flexo printing and gravure printing; Germany, Italy CO extrusion, dry compound machine; Japan, Italy, Taiwan's cutting, cutting machine, bag making machine, blown film machine.
