The 500ml Basic Round PET Bottle is produced by injection blow molding. First, the preformed plastic part of the bottle is made by injection molding technology, and then it is formed into the final bottle shape by blow molding. This process can ensure that the bottle has uniform thickness, high compressive strength, smooth surface, and precise bottle mouth, ensuring good fit with various bottle caps. It can provide anti-ultraviolet (UV) function. The bottle can effectively shield UV rays, thereby protecting the liquid in the bottle that is susceptible to UV rays, such as juice, cosmetics, etc., from quality variation or fading. In the cosmetics and personal care industry, the 500ml Basic Round PET Bottle is suitable for packaging liquid and paste products such as shampoo, shower gel, conditioner, body lotion, hand cream, etc. The transparent design of the bottle can help users clearly view the remaining amount of the product.
