PET preforms are typical injection molded products, which are easy to transport. They are mostly made of plastic material with uniform texture and good insulation. They are intermediate products for plastic bottles and oil drums.

Under a certain temperature and pressure, the mold is filled with raw materials and processed by the injection molding machine to form a bottle blank with a certain thickness and height corresponding to the mold.

PET bottles have strong applicability and are widely used in daily necessities, daily chemical packaging and other fields. From mold processing to machinery and equipment, they are very picky, easy to get started, but difficult to do. PET preforms are reprocessed by blow molding to form plastic bottles, including bottles used for packaging cosmetics, medicines, health care, beverages, mineral water, reagents, etc. This bottle making method is called a two-step method, that is, the preform is formed through injection molding. A method of forming PET plastic bottles through blow molding.

PET preform

PS preform

Low density (light weight), environmentally friendly, non-toxic, very good plasticity, poor toughness and brittleness, can not be made into transparent materials, so it can only be made into bottom bracket type blister, because it is easy to crack, this type of blister is not suitable for recycling

PP preform

The material is particularly soft, good toughness, environmentally friendly, non-toxic, and high temperature resistant.
