One of the greatest appeals of the blister pack is that it is a sealed package. For this reason, it is most commonly known for being used in the medical and pharmaceutical industries. You may recall the look of drugstore medications and the way they are carefully sealed within packages to allow for sterile conditions. Other uses of blister packs include such items as cosmetics, batteries, and other drugstore items such as floss or toothbrushes. The fact blister packs are sealed makes them a highlight for items that need to remain hygienic until used by a consumer or client.
