It depends on the size, weight, and protection properties of the packaged items.
1. PVC (polyvinyl chloride): It is one of the commonly used materials for blister packaging. It has strong toughness and good plasticity. It will become brittle when it encounters cold and cold weather. It is mainly transparent, and the color can be personalized according to different needs. The color of this type of material is the most common choice.
2. PET (polyethylene terephthalate): It is called environmentally friendly material. It has good hardness, toughness, high transparency, bright surface, environmental protection and non-toxicity. It is more transparent and transparent, but it is suitable for hot pressing of products requiring high frequency. It is difficult, and the price is relatively expensive. This type of material is more commonly used in high-end and high-demand products.
3, PS (polystyrene): light density, light material, environmentally friendly, non-toxic, plasticity is very good, but the toughness is poor, easy to crack, can not be made of transparent materials, PS film is often used for flocking the bottom layer, the color is diverse, can be matched with The choice of more characteristic colors is more suitable for the packaging of high-end products, so it is generally used for blistering.
4, PP (polypropylene): soft material, good toughness, environmentally friendly, non-toxic, high temperature, often used for high temperature product packaging, but its plasticity is poor, the difficulty of plastic is relatively large, the surface is lack of luster, showing milky white, It is only faintly permeable, and the color is slightly changed when heated. Therefore, products requiring high transparent packaging are not suitable for PP materials.
