How Are Plastic Bottles Commonly Used In Cosmetics Produced?

The production process of plastic bottles commonly used in cosmetics consists of two main processes: injection molding and blow molding. Firstly, the plastic granules are plasticized in the barrel of the injection molding machine, melted by heat and shear action of the feed screw, and then injected into a multi-cavity mold, where they take on the shape of an elongated tube. This process is mainly applicable to plastic bottles made of PP, PE, K material, AS, ABS, acrylic, PET, and so on.

Another common production process is the extrusion and blowing process, i.e., the plastic raw material is added into the extruder, heated and melted to plasticize and extrude the molten billet, and then put into the bottle mold to blow and expand the shape, and then take it out from the mold after cooling and shaping, trimming the waste edges to get the finished product. This process is mainly used to produce polyethylene, PVC plastic bottles.

For PET material plastic bottles, there is also an injection pull blowing process, that is, plastic raw materials by the plastic machine injection molding tube-shaped billet, and then put into the water bottle holder mold dry Lashin blowing injection molding, cooling to get the finished product. This type of process is key for the production of PET plastic bottles.

In addition, cosmetic packaging materials also include glass bottles, tubes, vacuum bottles and other main containers and color boxes, outer boxes, boxes and other auxiliary materials. Cosmetic bottle design is generally based on the design scheme, out of the mold, test pieces, production and manufacturing, masking, grinding and polishing, painting, high and low temperature test solid color and mixed color printing process of a production process.

The production process for plastic bottles commonly used in cosmetics involves a variety of materials and technologies, including but not limited to injection molding, extrusion blowing process and injection pulling and blowing process, as well as subsequent design and processing steps.
