When it comes to protecting the efficacy of ultra-sensitive pharmaceuticals, the packaging must step up and provide the necessary oxygen and moisture barriers.
Blister packs seal products in a cavity, usually with a paper backing or aluminum or film seal. These blister packs can be used for just about any product, but are common packages for small consumer goods, foods and pharmaceuticals. In the pharmaceutical space, blister packs are handy for creating unit-dose packaging: Each “blister” can hold one dose.
Blister packs protect product against external factors like humidity or UV rays.
While blister packs are usually made from plastics, newer paper varieties are more environmentally friendly.
