Blister packaging is a type of packaging that consists of a pre-formed plastic shell, often made from materials like PVC or PET, which holds products securely in place. This packaging is commonly used for items such as medications, small electronics, and consumer goods. The plastic shell is typically sealed with a backing material, often made of cardboard or aluminum, to protect the contents from moisture and contamination. The design of blister packaging allows for easy visibility of the product while providing a tamper-resistant seal. It is also lightweight and can be produced in various shapes and sizes, making it a versatile choice for manufacturers. Additionally, blister packaging can help extend the shelf life of products by providing a barrier against environmental factors.
