Definition of “blister”
Blister pack is a term for several types of pre-formed plastic packaging used for small consumer goods, foods, and for pharmaceuticals. The primary component of a blister pack is a cavity or pocket made from a formable web, usually a thermoformed plastic. This usually has a backing of paperboard or a lidding seal of aluminium foil or plastic. A blister that folds onto itself is often called a clamshell.
The expiry date is usually written in two ways:
- Using the abbreviation EXP
- Using the hourglass sign, e.g. ⌛ 2026/01
How long can you use an open package of contact lenses?
