Transparent plastic material company
Is a kind of transparent plastic blow molding processing of color is transparent white plastic packaging container, after bottle preform injection molding processing to form intermediate products, and then after form plastic blow molding processing, namely ldpe-g-nvp forming principle. Is through the transparent plastic raw materials for polyester class special materials through form a transparent bottle preform injection molding processing, transparent bottle preform after blow molding processing under certain pressure and temperature conditions, within the mold QiangMo volume expansion, according to the specifications mold is the thickness of highly transparent plastic bottles. At present, the more transparent plastic used in medicine, drinks, mineral water, candy, seasoning, wrapping. 1, PET transparent plastic material: qualitative hard, good toughness, high strength, surface brightness, environmental non-toxic, transparent and a variety of color sheet. Defect is PET high frequency thermal bonding is difficult, the price also slightly more expensive than PVC, this material has often been asked customers high-grade and environmentally friendly products to replace PVC, PET materials typically used to make the packing food, beverage, pharmaceutical industry of plastic bottles. 2, pp transparent plastic material: material of special soft, good toughness and environmental protection non-toxic, high temperature resistant, has often been made catering utensils or other high temperature resistant products packaging; But its poor plasticity, processing is difficult, the surface gloss, and process color becomes shallow, used to make disposable plastic bottles. 3, PVC transparent plastic material: soft, strong toughness, good plasticity, but make it transparent and a variety of colors, the common purpose of transparent PVC packaging masked category plastic bottles. Constant win to introduce you to the role of the transparent plastic packaging, as shown in the following: PMMA, commonly known as acrylic, transparency excellent material, the surface hardness is a bit low, easy to clean. , and is suitable for production of transparent insulation parts and the strength of ordinary parts. PS: colorless, transparent, pervious to light after PMMA, suitable for making insulating transparent parts. Decoration and chemical equipment. Optical instruments and other parts. PC: colorless, transparent material, suitable for making small instrument parts, insulation transparent and shock resistant parts. ABS: this kind of material is more expensive, promising in the field of decoration, packaging, etc.
What standard should cosmetic tube have in respect of oxygen resistance
Cosmetic tube as a container of cosmetics, do not react with the products is the most important function of tube, cosmetic ingredients are easy to cause the reproduction and growth of bacteria, in addition to its own factors, there is a part of the influencing factors because of the impact of oxygen and water; It can be seen that, the most important factor of cosmetic deterioration is oxygen, all cosmetic tube needs to have very good oxygen resistance and gas resistance (prevent the fragrance molecules in the cosmetics and the effective molecules of cosmetics overflow).
How do small and medium-sized enterprises develop product of cosmetics.
1. Don’t make too many products. There are more and more small and medium-sized cosmetic manufacturers. Their products almost cover all kinds of cosmetics. You can see that there are many products, but in fact, they have many disadvantages. The first one is that the sales volume is not necessarily high. The 80/20 law states that 80% of the benefits of any entity come from 20% of the products, that is, 80% of the products can only contribute 20% of the benefits, which is not economic. The second one is that too many product lines are relatively backward in management, and their own strength is insufficient, enterprises can’t grasp the dynamics of consumers' hearts, so there are a lot of products which are not need by consumers. Third, most companies focus on speculation and bargain hunting. Too many product lines limit the development of an enterprise. It is difficult for consumers to form an understanding of the enterprise without a major product. And it is impossible to find the market position without the c
What is the two in one tube and how to fill it in the rear? And the application of the product in skin care
Unlike a single branch tube, the most intuitive tube is a tube in the tube, which looks like a single branch, but can fill two kinds of material at the same time, at the same time extruding. When the material is not used, the material body is separated, and when used, mingling and merging.
Development of cosmetics to promote the development of tube packaging
With the rapid development of composite technology of plastics and different materials, composite tube gradually enters a variety of different packaging fields, such as high quality cosmetics, with its excellent water resistance, oxygen resistance and other properties and good convenience. This is changing the traditional concept of plastic composite tube packaging only for simple packaging of low-grade products.
