Cigarette pack

A pack or packet of cigarettes (also informally called fag packet in British slang; as in the idiom "back of a fag packet" or "fag-packet calculation") is a rectangular container, mostly of paperboard, which contains cigarettes. The pack is designed with a flavor-protective foil, paper or plastic, and sealed through a transparent airtight plastic film. By pulling the "pull-tabs", the pack is opened. Hard packs can be closed again after opening, whereas soft packs cannot.

Cigarette packs often contain warning messages depending on which country they are sold in. In the European Union, most tobacco warnings are standardised.

A patent has been granted for a cigarette package containing a container for disposal of cigarette butts.
