Blister packaging is a type of rigid plastic packaging that is sealed to a backing material, often cardboard or foil. It is commonly used for pharmaceuticals, small electronics, toys, and other consumer goods. The plastic shell, or blister, is typically thermoformed from a sheet of plastic into a cavity that holds the product. This cavity is then sealed to the backing material using heat and pressure. The backing material can be printed with product information, branding, and instructions.

The primary purpose of blister packaging is to protect the product from environmental factors such as moisture, dust, and tampering. It also provides a clear view of the product, allowing consumers to see what they are buying. The sealed nature of blister packs also serves as a tamper-evident feature, indicating if the package has been opened before purchase. For medications, blister packs offer a convenient way to dispense individual doses and are often organized by day or time.

Blister packaging can be made from various plastic materials, including PVC, PET, and HIPS, depending on the product's requirements and environmental considerations. The backing material is also chosen based on its suitability for sealing and printing. While offering good protection and presentation, the disposal of blister packaging can be a concern due to the combination of plastic and often non-recyclable backing materials.
