Composite hoses in the field of chemical analysis
Composite hoses in application and development trend in the field of cosmetic
cut off due to the composite hose has good performance, strong chemical resistance and good printing adaptability and other characteristics, widely used in toothpaste, cosmetics and other products packaging. At present, along with the adoption of some new materials and new technology, composite hose presents the following trends. A further strengthening of environmental protection, environmental protection is more than just the processing of packaging waste, should also include pollution to the environment in the process of production and consumption of resources, etc. Lu: su composite hoses and all plastic composite hoses, maximize the use of economic, easy recycling of sheet, especially all plastic composite hoses, when using the EVOH ( Ethylene vinyl alcohol copolymer) And other high barrier property material, completely replace the aluminum foil, pipe can be completely recycled and biodegradation. Three sakura has been in lu: su composite hose successfully developed on the basis of all plastic composite hoses, main widely used in toothpaste packaging. But all plastic pipe, compared with aluminous model multiple tube on the compressive resilience and barrier property has certain gap, in quite a long time that will limit all plastic composite hose in place of aluminous model multiple tube in an all-round way. Second, health performance requirements more and more high composite hose is mainly suitable for oral care products and cosmetics packaging, therefore, from the ensure the safety of their products performance considerations, health is always first consider the factors of performance, and there are increasingly enhanced. Reflect on the raw materials, first of all films, particle, adhesive, printing ink and other physical and chemical indicators and abnormal toxicity has certain restrictions; On the choice of process, the different composite technology of sheet and the solvent residual amount of hose will have different effects; In addition, the production workshop environment, the air is clean, such as microbial quantity, suspended solids, such as dust, and the number of production workers health, health performance influence the final product. In addition, according to different target market, its different to the requirement of pipe health performance, such as exported to Japan, the United States and other countries, the residual solvents in the ink, heavy metal content and so on have very high requirements. Three, the trend of low cost due to the manufacturer of composite hoses used for raw material cost down, objectively caused the pipe manufacturer continuous composite hose down the production cost, specific displays in: 1, the use of thin aluminum foil and tight structure between the layers. The use of aluminum-plastic composite tube sheet of aluminum foil, from the initial 40 mu to prevailing now 20 mu to 30 mu, the thinnest 12 mu has been done, at present, three cherry has been used on many lu: su composite hose 12 mu aluminum foil thickness of the sheet, has received the good effect. , of course, the thickness of aluminum foil, is by no means simple subtraction, to do the aluminum foil thickness decrease at the same time to ensure the good product performance, in its every thinning thanks to technology innovation and improvement of the equipment or other materials. 2, reduce the loss in the process of production. For lu: su composite hose production, try to use width is larger in the gravure printing technology and double or more co-extrusion technology, and improve process, improve production speed, to maximize the efficiency, reduce wear and tear. Four, the customer request the current individuation, used in composite hoses and will win more and more emphasis on personalized design. Such as non-standard pipe diameter and the length to diameter ratio of individuation, distinctive pipe shoulder and cap, elliptical, etc all kinds of play, the choice of the unique shape, sealing incision sealing membrane is widely used, such as hot stamping, silk screen printing, label modification technology, and optical variable ink, laser pointer, etc. The use of anti-counterfeiting technology. In a word, with the further development of composite hoses, its application in the field of cosmetic products will be more and more widely.
