Blister packaging, not long ago considered a less significant segment of the North American pharmaceutical packaging industry, is now outpacing most other industry segments. In 2010, blister represented 17% of the global market and recorded $8.1B in revenue, according to Pharmaceutical Packaging Industry – 2011 Yearbook. GBI Research. Impressive figures, yet they represent merely the low end of blister's growth curve. The yearbook data also projects that between 2010 and 2017, blister packs are expected to emerge as the second-fastest-growing sector.
Product Protection. Blister packaging's level of product safety makes it an increasingly practical option, one that satisfies the demands of manufacturers, regulatory organizations and consumers. Individual tablets or capsules are sealed within their own cavity, usually made of thermo-formed plastic or cold-form aluminum, protecting the drug from contaminants such as moisture and oxygen by a barrier of foil, film or paperboard. Forming of the blister, filling with product and sealing it are all completed on one machine for minimal exposure to external influences which can alter the properties of the drug. Ideally, this process occurs in a controlled production environment for a maximum level of protection.
