Application of cosmetic plastic hose in cosmetics and medicine packaging

Whether it is cosmetics, medicine or food, the first thing to consider is hygiene performance, followed by mechanical strength, barrier performance, printing adaptability and chemical resistance. Of course, we must also consider the economy and convenience of use. Compared with the packaging of other products, cosmetic plastic hoses have higher requirements for water resistance and oxygen resistance. On the one hand, fat-containing water may contain mold and yeast, which can produce fat oxidation, fat hydrolysis, and oxidation into fatty acids and glycerin. In addition, in order to prevent agglomeration, hardening and deterioration of some powdered products due to moisture absorption, many cosmetic packaging needs to block the entry of moisture. On the other hand, some products containing water are used to cleanse the skin. Therefore, it is necessary to maintain a certain moisture content for a certain period of time. Therefore, it is necessary to prevent water from escaping. Oxygen is the main cause of cosmetic rancidity. Most cosmetics contain oils. Unsaturated bonds in oil are easily oxidized, causing deterioration and rancidity. As long as a small part of unsaturated oil starts to oxidize, it will lead to complete rancidity of the oil and reduce product quality. Therefore, in the production, storage and use of cosmetics, rancidity should be avoided as much as possible to prevent oxygen from entering. Generally speaking, plastic hoses have advantages that other materials cannot match. Since its birth, it has appeared in cosmetics and pharmaceutical packaging. At present, it has become an indispensable form of cosmetics and pharmaceutical packaging. According to the material classification, plastic hoses can be divided into single-layer hoses and multi-layer hoses. Single-layer hoses include metal hoses and plastic extruded hoses; multilayer hoses include aluminum-plastic composite hoses, plastic composite hoses and plastic co-extruded hoses. Plastic hoses can be divided into seamless pipes and slotted pipes. Most of the large plastic hose manufacturers in China have introduced world-class advanced production equipment, such as high-speed tube making machines from KMK and Aisa in Switzerland; flexographic printing machines and gravure printing machines in the United States, Japan or Taiwan; CO extrusion machines in Germany and Italy Exporting and dry laminating machines; slitting, slitting machines, bag making machines and film blowing machines in Japan, Italy, and Taiwan.
