Bubble pack

Bubble pack or blister pack is a type of packaging that is commonly used in the pharmaceutical industry and consumer goods. The pack consists of a pre-formed plastic shell, shaped to contain the product, and a backing of paperboard or a lidding seal of aluminum foil or plastic film.

History

The first patent for a blister pack was granted in the United States to Harold K. Sperber in 1953. The invention was initially intended for use in the pharmaceutical industry to provide a new method of packaging pills that would ensure product integrity and security.

Design and Production

The design of a bubble pack involves the creation of a mold that matches the shape of the product to be packaged. The plastic used in the pack is heated and then molded into the required shape. The product is then placed into the formed plastic and the backing material is applied. The backing material is usually heat-sealed to the plastic, creating a secure package.

Bubble packs are produced using a variety of materials. The most common plastic used is PVC, due to its low cost and ease of processing. Other materials used include PET, PP, and PE. The choice of material depends on the product to be packaged and the required barrier properties.

Uses

Bubble packs are used in a wide range of industries. In the pharmaceutical industry, they are used to package tablets and capsules. They are also used in the packaging of small consumer goods, such as batteries, toys, and electronics. Bubble packs provide a high level of protection for the product, as well as a clear view of the product for the consumer.

Environmental Impact

The environmental impact of bubble packs is a topic of concern. The majority of bubble packs are not recyclable due to the combination of different materials used in their construction. This has led to calls for the development of more sustainable packaging solutions.
