When using, the drink in the bottle can be drunk by opening the cap. When the bottle is produced, the bottle body (including the bottle mouth part) is usually completed by a combination of injection molding and blow molding. However, the blow molding process usually makes the bottle body uneven in thickness, and the production cost is high due to secondary processing. At the same time, since a two-foot sleeve label is required after blow molding, the difference between the sleeve label material and the bottle body material is not conducive to recycling and other problems.
