läpipainopakauksien

Läpipainopakkaus, also known as blister packaging, is a type of rigid transparent plastic packaging. It consists of a cavity or pocket, usually formed from a film of plastic such as polyvinyl chloride (PVC), polyethylene terephthalate (PET), or polystyrene (PS), into which a product is placed. This plastic cavity is then sealed to a backing material, commonly made of paperboard, aluminum foil, or plastic film. The sealing process typically involves heat or radio frequency welding.

The primary purpose of läpipainopakkaus is to protect the product from external environmental factors like moisture, light, oxygen, and physical damage during transit and storage. The transparent nature of the plastic allows consumers to easily see the product inside, which can be a significant advantage for marketing and sales. This visibility also helps to prevent tampering and ensures product integrity.

Läpipainopakkaus is widely used for a variety of products, including pharmaceuticals (e.g., pills, capsules), consumer goods (e.g., batteries, small electronic components, toys), and food items (e.g., blister packs for blister-packed candies or single-serving portions). The design can be customized to accommodate different product shapes and sizes, offering a secure and often tamper-evident containment solution. The blister pack is typically opened by tearing or pushing the product through the backing material.
