Abstract
Description
Technical Field

[0002] Common beverage bottles are generally made of polyester, polyethylene or polypropylene as raw materials, and after adding corresponding organic solvents, they are heated at high temperature and then blow molded, extruded or injected through plastic molds. Since plastic is difficult to degrade and has a low recycling rate, it is very environmentally unfriendly. Therefore, beverage bottles made of environmentally friendly paper materials are currently available on the market, but most of the bottles made of pulp are integrally molded in the mold. This type of bottle generally has high requirements for the mold and needs to be molded by injection molding in a closed mold cavity, which causes pulp to be missing in some parts of the pulp bottle during wet embryo molding, resulting in a high defective rate and a high production cost of the mold.
