The focal point of a blister pack's various materials is a piece of thermoformed plastic (such as PVC, PET, PETG, etc.). A backing substrate (most commonly made from blister-board) is attached to the backside of the thermoformed plastic container. Two-sided blister packs that do not use a blister-board backer but instead use another piece of plastic are commonly called clamshells.

Benefits and Uses of Blister Packs

Blister packs are sturdy and robust packaging materials that are an excellent choice for protecting products from harm. Blister packs also protect products from other problems like humidity and contamination for extended time-frames. Some types of blister packs are made with unique plastic formulations that will actually block UV rays from touching the product within.

There is an extensive range of products that are packaged in blister packs. These items include products such as toothbrushes, sleep aides, mechanical parts, and a vast amount of other small to large-sized products. If you suffer from allergies and rely on over the counter antihistamines to find relief, most likely you are familiar with blister packs. They are commonly used to house these types of medications.
