Blister Pack
No Comments Yet

A blister pack is a type of product packaging where merchandise is shipped with a descriptive card under clear plastic wrap. In addition, a blister pack can be packaged in clear or opaque plastic or metal-foil seal which holds the product against a sheet of cardboard.  Blister packs are useful for protecting the product against external factors such as humidity and contamination for extended periods of time. Opaque blisters also protect sensitive products against daylight. Another term for blister pack is bubble wrap.

Blister packs are used to package products such as toys, hardware, medication, etc.

Many blister packaging machines use heat and pressure via a die to form the cavity or pocket from a roll or sheet of plastic. In recent years, improvements in cold forming, specifically allowing steeper depth/angles during forming, which minimizes the amount of material used for each cavity—have helped this technology increase. The main advantages of the plastic-based blister pack are its more compact size compared to cold formed aluminum and its transparency to see the product.*
