In the production and processing of anti-uv pet bottle packaging, there are certain production processes and methods. Next, we will understand what are the anti-uv pet bottle packaging production processes?

Extrusion and blowing process, that is, the plastic raw materials are added to the extruder, after heating, melting and plasticizing, the molten billet is extruded, and then put into the bottle mold to blow and form, and then removed from the mold after cooling and shaping, and the finished product is obtained after repairing the waste edge. This process is mainly used to produce polyethylene, polyvinyl chloride anti-uv pet bottle packaging, such as milk bottles, soy bottles and so on.

In the process of injection drawing and blowing, the plastic raw material is injected into a tubular blank by an injection molding machine, and then put into a bottle mold by stretching and blowing, and the finished product is obtained after cooling. This process is mainly used to produce PETanti-uv pet bottle packaging, such as mineral water bottles.

anti-uv pet bottle packaging is passed after blow molding, the plastic is heated to melt, and then pressed into a special blow molding mold and the internal air pressure, pressure, mold plastic, to form the shape of the final product, because the shape of the bottle outward pressure time, so the emphasis is on the bottle itself inward, When the heating temperature reaches a certain level, the plastic will be softened, and the resistance of the pressure will become smaller, so the bottle will become smaller and smaller.

The common anti-uv pet bottle packaging production process includes squeeze blowing process and injection and draw blowing process. In fact, there are many other anti-uv pet bottle packaging production processes, including injection molding, calendering, blow molding, molding, laminating, casting, and so on.
