Cosmetic plastic tubes are emerging in cosmetics and pharmaceutical packaging

Cosmetic plastic tubes are easy to use, economical, and hygienic, and have become one of the main packaging varieties for cosmetics, medicine and food. Since the 1990s, China has introduced a large number of advanced composite tube production equipment from Europe, America, Japan and Taiwan Province, and the development momentum is very strong. Multi-layer, thin-wall and transparent plastic composite tubes are the future development trend.    Whether it is cosmetics, medicine or food, packaging must first consider hygiene performance, followed by mechanical strength, as well as barrier performance, printing adaptability and chemical resistance. Of course, the economy and convenience of use must also be considered.   Compared with other product packaging, cosmetic packaging has higher requirements on water and oxygen resistance. On the one hand, the water-containing fat may contain mold and yeast, which will cause fat oxidation, fat hydrolysis, and oxidation into fatty acids and glycerides. Therefore, increasing the moisture in the oil will cause the hydrolysis of the oil on the one hand, and accelerate the auto-oxidation reaction on the other hand, provide a living environment for microorganisms, and reduce the vitality of certain antioxidants such as polyamines. In addition, some powdered products must prevent the absorption of moisture and cause agglomeration, hardening and deterioration, so many cosmetic packages need to block the entry of moisture; on the other hand, some water-containing products are used to clean the skin, so it must be To maintain a certain moisture content during the period, therefore, it is necessary to prevent the escape of moisture. Oxygen is the most important factor causing cosmetic rancidity. Most cosmetics contain oils and fats. The unsaturated bonds in oils are easily oxidized and cause deterioration and rancidity. As long as a small part of the unsaturated oil starts to oxidize, it will cause the complete rancidity of the oil, which will reduce the quality of the product. Therefore, in the production, storage and use of cosmetics, every effort should be made to avoid the occurrence of oil rancidity and prevent the entry of oxygen
