What materials are common blisters made of
The author:
PET (Polyethylene terephthalate) hard sheet.
PVC (polyvinyl chloride) hard sheet.
PS (polystyrene) hard sheets have low density, poor toughness, and are prone to combustion. When burned, styrene gas (a harmful gas) is generated, so they are generally used to produce various industrial plastic trays.
PVC hard sheets have moderate toughness and are not easy to burn. When burned, chlorine gas is generated, which has a certain impact on the environment. PVC is easy to heat and can be sealed by sealing machines and high-frequency machines. It is the main raw material for producing transparent blister products.
Blistering is a plastic processing process that mainly involves heating flat plastic hard sheets to soften them, using vacuum to adsorb them onto the surface of the mold, cooling them, and forming them. It is widely used in industries such as plastic packaging, lighting, advertising, and decoration.
