cosmetic plastic tube

Cosmetics, pharmaceutical and food packaging, the first thing to consider is the health performance, followed by mechanical strength, and barrier properties, printing adaptability and chemical resistance, etc. Of course, must also consider economic and ease of use.
Plastic hose is convenient to use, economic, health, has become the cosmetic plastic tube main cosmetics, pharmaceutical and food packaging one of varieties. Since the 90 s, China imported from Europe and the United States, Japan and Taiwan province of advanced composite hose production equipment, the development momentum is very fierce. Multilayer, thin and transparent plastic composite hose is the development trend of the future.
Compared with other products packaging, cosmetics packaging higher requirements on the resistance and water resistance of oxygen. On the one hand, water cut fat could contain a mould and yeast, will produce the oxidation of fat, fat hydrolysis, oxidation into fatty acids and triglycerides. Therefore, increase the moisture in oil, on the one hand, can cause oil hydrolysis, on the other hand will accelerate oxidation reaction, automatically provides the microbial living environment, reduce some antioxidants such as multivariate amine vigor. In addition, some flour products to prevent absorb moisture and cause sclerosis of agglomerate, metamorphism and so on, so a lot of cosmetics packaging needed to block the water into the; On the other hand, some of the water product is used to clean the skin, so must be in a certain period of time to make it keep certain moisture content, therefore, must prevent moisture to escape again. Oxygen is the main factor that cause cosmetics rancidity Z.
Most cosmetics contain grease composition. Oil empty cosmetic tubes in the unsaturated bond very easy oxidation and cause metamorphism, rancidity. As long as there is a small part of unsaturated fat oxidation, it could cause oil rancidity completely, so that product quality decline. Therefore in the process of the production, storage and use of cosmetics to try our best to avoid the phenomenon of oil rancidity, prevent oxygen to enter.
Taken together, plastic hose with other materials incomparable advantages, therefore, since the advent of the cosmetics and pharmaceutical packaging. Now more become indispensable to cosmetics and pharmaceutical packaging form
Cosmetics function and role of more and more refined, and more and more cosmetics with integrated functions, class differences obviously, packaging form dazzling; At the same time, the merchants in order to better promote their products, cosmetics for the different characteristics, suitable for classification and packaging.
Currently used plastic hose cosmetics packaging is mainly composed of aluminium - plastic composite hose, pull - plastic composite hose and plastic co-extrusion of hoses, can meet various kinds of need of health, such as not cosmetics packaging.
Aluminium - plastic composite hose is aluminum foil, plastic film, through empty cosmetic tubes the pneumatic composite plate of the production process, and then through special machine processing into tubular packaging container, typical structure of PE/EAA PE/AL/PE EAA/PE. Aluminum plastic composite tube is mainly used for packaging hygiene and high barrier property of cosmetics, the barrier layer is commonly aluminum foil, the barrier property depends on the aluminum foil pinhole degree. As technology continues to improve, the thickness of aluminum foil shielding aluminum plastic composite tube reduced from 40 m to 12 m, 9 m even, thus greatly save the resources.
