Blister packaging is used in small commodities on a plastic preformed packaging. Blister packaging is an inexpensive option for creating packages that are durable, transparent, and tamper proof. These clear plastic blister packs are used in conjunction with a cardboard blister card to keep the product in full view for the customer to examine.
The blister packaging is attached to the blister card through a heat-sealing process that allows the product to be displayed in a wide variety of methods. While this heat sealing process can be done with highly automated equipment, the use of blister packs is somewhat limited to light weight items. For heavier items, one should consider using plastic clamshells or double blisters.
