Blister Pack is a term for several types of pre-formed plastic packaging used for small consumer goods, foods, and pharmaceuticals.
Blister Packs are a rigid package design consisting of PVC plastic which is bonded to an adhesive coated paper or foil backing. Intended for single dosage of a tablets, capsules, or softgels, blister cards are designed to protect the contents and integrity of the product. The PVC plastic is formed using specific tooling from our library of custom-built tooling options. Once the plastic is formed, the product is inserted into the cavities and the card is prepared for foil backing application. The plastic and foil are joined together at the sealing station where heat and pressure are applied. This process activates the adhesive on the face of the foil and creates a bond between the PVC plastic and the foil backing, producing a finished product blister.
The primary component of a blister pack is a cavity or pocket made from a formable web, usually a thermoformed plastic. This usually has a backing of paperboard or a lidding seal of aluminum foil or plastic. A blister that folds onto itself is often called a clamshell.
Blister packs are useful for protecting products against external factors, such as humidity and contamination, for extended periods of time. Opaque blisters also protect light-sensitive products against UV rays.
