Blister pack

Blister pack is a type of packaging that is used to hold small consumer goods, pharmaceuticals, and for retail and wholesale purposes. The primary component of a blister pack is a cavity or pocket made from a formable plastic, 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.

History

Blister packs have been in use since the 1960s and are becoming more prevalent in the pharmaceutical industry. The first patent for a blister pack was granted in the United States in 1965. The popularity of blister packs in the pharmaceutical industry is due to their ability to protect the quality and sterility of products.

Design and production

The process of creating blister packs often involves several steps. First, the plastic is heated and then molded into the desired shape. This is typically done using a mold or die. The plastic is then cooled and removed from the mold. The product is placed in the formed plastic and the backing material is applied. The backing material is often heat-sealed to the plastic, creating a tight seal that protects the product.

Uses

Blister packs are used for a wide variety of products. They are commonly used for pharmaceutical packaging, as they provide a barrier against moisture, gases, and light. This helps to extend the shelf life of the product. Blister packs are also used for consumer goods such as toys, hardware, and electronics.

Advantages and disadvantages

Blister packs have several advantages. They provide a high level of protection for the product, are easy to use, and are cost-effective. However, they also have some disadvantages. They can be difficult to open, especially for elderly or disabled individuals. They also generate a significant amount of waste, as the plastic and backing material are often not recyclable.
