Plastic hose easy to use, economical, hygienic, and has become one of the major packaging varieties of cosmetics, medicine and food. Since the 90s of the last century, China has introduced a large number of advanced composite hose production equipment from Europe, the United States, Japan and Taiwan Province, and the momentum of development is very fierce. Multi-layer, thin-walled and transparent plastic composite hose is the future trend.
Whether it is cosmetics, medicine or food, the packaging must first consider the health performance, followed by the mechanical strength, as well as barrier properties, printing adaptability and chemical resistance. Of course, you must also consider the economy and ease of use.
Compared with the packaging of other products, cosmetic packaging in the water and oxygen on the higher requirements. On the one hand, watery fats may contain molds and yeasts, resulting in the oxidation of fats, the hydrolysis of fats, the oxidation of fatty acids and glycerides. Therefore, increasing the amount of oil in the oil, on the one hand will cause the hydrolysis of oil, on the other hand will accelerate the auto-oxidation reaction, providing microbial living environment, reducing the vitality of certain antioxidants such as polyamines. In addition, some powder products to prevent absorption of water caused by caking, hardening deterioration, so many cosmetic packaging need to block the entry of moisture; the other hand, some water-containing products are used to clean the skin, it must be certain Period to maintain a certain moisture content, therefore, must also prevent the water from escaping. Oxygen is the most important factor that causes cosmetics rancidity. Most cosmetics contain oils and fats. Unsaturated bonds in oils are easily oxidized and cause spoilage. Unsaturated fat as long as a small part of the oxidation began, it will cause the grease completely rancidity, so that product quality decline. Therefore, cosmetics in the production, storage and use of the process should try to avoid the occurrence of rancidity, stop oxygen from entering.
Taken together, plastic hoses have the advantage of being difficult to compare with other materials, so they have come to prominence on cosmetic and pharmaceutical packaging since they first became available. At present, cosmetics and drugs have become an indispensable form of packaging.
Plastic hose according to the material classification can be divided into single-layer hose and multi-layer hose. Single-layer hoses include metal hoses and plastic extrusion hoses; multi-layer hoses include aluminum-plastic composite hoses, plastic composite hoses and plastic coextruded hoses.
According to the classification of processing technology, plastic hose can be divided into seamless pipe and seam pipe.
The rapid development of China's plastic hose, there has been the Shenzhen Li Shixing and Shanghai Sakura Packaging Materials Co., Ltd. and other enterprises represented by the composite hose manufacturers. Among them, Shenzhen Liushi Petrochemical Co., Ltd. has produced 5-layer composite plastic hose since 1992 and is the first manufacturer in China to produce 5-layer composite hose.
China formed a large-scale plastic hose manufacturers, most of the introduction of Swiss KMK, AISA high-speed pipe machine; United States, Japan or Taiwan Province flexographic printing presses and gravure printing presses; Germany or Italy co-extrusion laminating machine and dry composite Machine; Japan, Italy or Taiwan's cutting slitting machine, bag making machine and blown film machine and other world-class advanced production equipment.
Cosmetics and pharmaceuticals are the largest users of plastic hoses, which are currently used primarily for the packaging of some condiments. The application of other fields has yet to be expanded.Cosmetic Hoses
