What Is Bottle Preform

Bottle preforms are formed by injection molding by filling raw materials into the gun mold of a mold at a specific temperature and pressure, under the working conditions of an injection molding machine. After injection molding, they are semi-finished products of intermediates, and then blown into final products.

PVC
The most commonly used blister material is soft, strong in toughness, and good in plasticity, which can be made into transparent and various colors. Transparent PVC is commonly used for packaging products such as electronics, cosmetics, toys and gifts.
PET
Hard in texture, good in toughness, high in strength, bright on the surface, environmentally friendly and non-toxic, with transparent and multi colored sheets. The disadvantage is that PET high frequency heat sealing is relatively difficult and much more expensive than PVC. This material is often replaced by users who require high-end and environmentally friendly products. PET material is generally used to make plastic bottles, food packaging boxes, and so on
PS
Low density (light weight), environmentally friendly and non-toxic, with excellent plasticity, poor toughness and brittleness, and cannot be made into transparent materials. Therefore, it can only be made into base type blisters, which are prone to cracking and are not suitable for recycling
PP
The material is particularly soft, has good toughness, is environmentally friendly, non-toxic, and resistant to high temperatures. It is often used as a packaging for dining utensils or other high-temperature products; But its plasticity is poor, processing difficulty is high, surface glossiness is poor, and the color will become lighter during processing.
