Material for the production of cosmetics container commonly used materials

The material of plastic bottles are usually for PP, PE, K, AS, ABS, acrylic, PET, etc. Commonly used in cosmetics container walls thicker cream bottle, bottle caps, bottle stoppers, gaskets, pump head, dust cover for injection molding; PET bottle blowing for two-step forming, tube embryos for injection molding, finished product packaging for the bottle blowing. Other such as container wall thinner lotion bottle, washing bottle to bottle blowing. ABS engineering plastics, not environmental protection, high hardness, not directly with the cosmetics, food contact, in acrylic cosmetics container packaging are generally cover, inside shoulder sleeve material. Yellow or milk white in colour. PP, PE belongs to the environmental protection material, can be directly and cosmetics, food contact, is the main material of filling organic skin care products, material color white, translucent. According to the different molecular structure, can achieve three different degree of hard and soft. PET belongs to the environmental protection material, can be directly and cosmetics container, food contact, is the main material of filling organic skin care products, PET material is qualitative soft, color is transparent. PCTA, PETG belong to environmental protection material, can be directly and cosmetics, food contact, is the main material of filling organic skin care products, material is qualitative soft, transparent, PCTA and PETG is soft easy to scratch, and not commonly used spray-painting multi-purpose printing. AS low hardness, brittle, When knock is ringing voice) Color, transparent color, and the blue can direct contact with the cosmetic, food, in the ordinary course of lotion bottle, vacuum flask, generally is the material of the bottle, cream bottle of small capacity. Transparent. A transparent acrylic material is hard, vein, and the color white. X and acrylic transparent texture in order to keep the handiest spray bottle, or in injection for coloring. PETG injection molding process is stable and does not need special design of the injection molding machine, the molding temperature is 215 ℃ ~ 235 ℃ or so, only the PC injection molding process is not easy to control, the injection temperature about 280 ℃, in contrast they can better save power. PETG in injection molding is not easy to produce stress, it is by their molecular structure and its good ductility. And PC is easy to produce internal stress, and more a stress relief the postprocessor. The internal stress of injection molding products, great hazard, which is a severe case of stress cracking, it also will increase the unnecessary of customer complaints or claim. 394.
