Plastic hose has good development advantages and physical and chemical properties
Plastic hoses are easy to use, economical and sanitary, and have become one of the main packaging varieties for cosmetics, medicines, and food. Since the last century, China has introduced a large number of advanced composite hose production equipment from Europe, the United States, Japan and Taiwan, and the development momentum is strong. Multi-layer, thin-wall, transparent plastic composite hose is the future development trend. 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. The use of packaging materials with good barrier properties (good airtightness) and strict sealing technology and requirements can effectively prevent the exchange of materials in the packaging content, thereby avoiding weight loss, effect loss and secondary pollution of the content. . 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 the unsaturated oil starts to oxidize, it will cause the oil to become completely rancid and reduce the quality of the product. 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. Therefore, since its birth, it has appeared in the packaging of cosmetics and medicines. At present, it has become an indispensable form of cosmetics and pharmaceutical packaging.
