Classification of preforms.

PVC preform

The most commonly used blister material is soft, strong, and malleable. It can be made into transparent and various colors. Transparent PVC is commonly used to package electronics, cosmetics, toys, gifts and other products.

PET preform

Hard quality, good toughness, high strength, bright surface, environmental protection and non-toxic, transparent and multi-color sheets. The disadvantage is that PET high-frequency heating is more difficult, and the price is much more expensive than PVC. This material is often replaced by users who require high-grade and environmentally friendly products. PET materials are generally used for plastic bottles, food packaging boxes, etc.

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. It is often made into packaging for dining utensils or other high temperature resistant products; but its plasticity is poor, processing is difficult, surface gloss is poor, and the color becomes lighter during processing.
