Blister packaging is a common form of packaging that transforms plastic sheets into the desired shape through processes such as heating and suction, and then undergoes cutting, edge sealing, and other treatments to ultimately form a sealed packaging container. Vacuum packaging has various advantages, but there are also some shortcomings.
Vacuum forming is a thermoplastic processing technology mainly used to make various packaging containers and components. Vacuum forming materials usually use plastic sheets such as polypropylene (PP) and polystyrene (PS), which can be softened by heating and then transformed into the desired shape under the action of suction. Blister packaging has the characteristics of good transparency, toughness, impact resistance, and sealing, and is widely used in packaging in industries such as food, medical devices, and cosmetics.
