take back bottle

The preform is the initial form of a plastic bottle. Processing it into a complete material requires many steps. Before making it, it is necessary to select its raw materials, including polyethylene, polyamide, polyoxymethylene, etc. When purchasing, you should also pay attention to choose according to your own requirements. So what are the specific material choices? 1. Polyethylene The English abbreviation of polyethylene is continuous spray bottles "PE". High pressure polyethylene has low crystallinity, low density and soft texture. Compared with low pressure polyethylene, it has higher transparency, excellent impact resistance and low temperature resistance, but it is not heat resistant.The air permeability of low pressure polyethylene is worse than that of high pressure polyethylene, but the impact resistance is not as good as that of high pressure polyethylene. Both polyethylenes are prone to cracking under stress.2. Polyamide The English abbreviation of polyamide is "pa". There are many types of polyamides. The chemical structure of polyamides varies depending on the synthesis method, and their properties are also different. However, their similarities and properties are similar. Polyamide has high crystallinity, high mechanical strength, good toughness, and good fatigue resistance.The preform made of polyamide is easy to color and shape, and can be used for a long time at room temperature. However, its heat distortion temperature is low, its hygroscopicity is large, and its dimensional stability is poor. 3. Polyoxymethylene Polyoxymethylene (POM) is a highly crystalline material, referred to as POM. Polyoxymethylene is a very elastic material. It has strong chemical stability, impact resistance and creep resistance, and has high stiffness, strength and wear resistance. It is a common material.,continuous spray bottles ...ادامه مطلب

The packaging of cosmetics should establish the design and direction of the brand in many factors such as aesthetics, creativity, packaging materials, and market positioning, and strive to stand out among similar products.

Product brand positioning needs to be clear and innovative.
