Conventional transparent materials are PET, PVC, PETG.
PET is an environmentally friendly material. The transparency is relatively higher than that of PVC. It is flammable, and the cost is higher than that of PVC.
PVC material is not environmentally friendly. Class material, but it is non-flammable, can be used for hot-press blister packaging, the cost is relatively low, usually used in the factory internal turnover or used in the hardware industry packaging.
PETG combines the advantages of PET and PVC It not only has the environmental protection type of PET, but also has the incombustibility of PVC. It is generally used for custom high-quality or transparent blister packaging exported to Europe and the United States, and the price is also the most expensive of the three materials.
