Cosmetics hoses on the cosmetics and pharmaceutical packaging
In cosmetics and pharmaceutical packaging cosmetics cosmetics hose hose use convenient, economic, health, has become the 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.
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.
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 most important factor of cosmetics rancidity.
Most cosmetics contain grease composition.
Oil 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.
Plastic hose according to the material classification can be divided into multiple single hose and hose.
Single hose including metal hose and plastic extrusion hose;
Multilayer hose including lu: su composite hose, plastic composite hose and plastic extrusion hose.
Classified by the processing technology, is plastic hose can be classified into seamless tube and tube.
Fast development of Chinese plastic hose, petrochemical star appeared in shenzhen and Shanghai SAN ying packaging material co. , LTD. , and other enterprises represented by the composite tube production enterprise.
The shenzhen petrochemical star 5 layer composite plastic hose production since 1992, is China's first five layer composite hose production enterprises.
Scale plastic hose production enterprises in China, mostly for KMK Switzerland, AISA high-speed pipe-maling machine;
The United States, Japan and Taiwan province of flexographic printing and gravure printing;
German or Italian composite extrusion machine and dry compound machine;
Japan, Italy and Taiwan article segmentation cutting machine, bag making machine and film blowing machine and other world-class advanced production equipment.
Cosmetics and drugs is one of the largest users, plastic hose part at present is mainly used for flavoring in food packaging.
Other remains to be development in the field of application.
