The main materials and characteristics of injection blowing and injection blowing oil plastic container bottles

At present, the top plastic container manufacturers on the market can choose from a wide variety of materials for injection blowing and injection stretch blowing bottles. They all have their own distinct characteristics, physical and chemical properties, and suitable production and molding processes. The following mainly introduces the characteristics, application fields, and application requirements of plastic materials that can be used for injection blowing and injection stretch blow molding.

High-Density Polyethylene (HDPE)

The earliest PE material used in bottle blowing is low-density polyethylene. Later, with the development of HDPE, due to its comprehensive properties, good processing properties, and cost. It is widely used for daily necessities, medicines, cosmetics packaging, and containers to adapt to the shampoo bottle trend.

HDPE has good adaptability to the molding process, high thermal stability, and wide processing temperature range, and is often used in extrusion blow molding and injection blow molding. Among them, injection blow molding has a great advantage in the application of small volume HDPE bottles in medicine, cosmetics, and food due to the high dimensional accuracy of the mouth, and has become the most important material in the injection blowing process.
