Both PET and PETG materials can be made transparent, but other materials cannot. The PET raw material is mainly white and crystallized; the PETG raw material is transparent and modified into an amorphous body on the basis of PET. Compared with PET, PETG has higher transparency, better chemical resistance, better oil resistance, and better weather resistance (yellowing) than PET. The procurement cost of PETG is 2-3 times that of PET. From the appearance point of view, the PETG bottle has sharper edges and corners than the PET bottle, and the hardness is also higher. Because PETG adopts the injection molding process, the cut tail can be seen at the bottom of the bottle, while the PET bottle uses It is a blow molding process and the bottom of the bottle is smooth. Both PET and PETG can be processed with additional color, sandblasting, bronzing, and labeling.

The PP cosmetic packaging bottle is hollow molded by the injection stretch blow method, that is, the molten PP of the injection molding machine is injected into the injection mold, and a transparent bottomed parison is formed by rapid cooling, and then the parison is heated inside and outside in another station to reach a certain level. After the temperature, the preform is extended to a certain proportion, and then filled with compressed air to obtain the desired hollow product. Neither PET nor PETG is heat resistant, while PP can reach filling temperatures of 100°C. PP cannot be transparent.

PE and ABS cosmetic packaging bottles are also injection-molded and cannot be made transparent.

Acrylic, also known as PMMA or Acrylic, is derived from English acrylic (acrylic plastic). The chemical name is polymethyl methacrylate. It is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weather resistance, easy dyeing, easy processing and beautiful appearance. It is used in the construction industry.
