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.

The size of a pack is often regulated. Government agencies usually set a minimum pack size.

In Australia, the most common quantity per pack is 25, but some brands have 26 or 20 (the legal minimum), with 30, 40 and even 50 packs also sold.

In Canada, most packs sold have 25 cigarettes, but packs of 20 are also popular.

In many European countries, increases of cigarette tax can cause the quantity of cigarettes in the pack to change to achieve the same end price.

In Malaysia, the sale of packs containing fewer than 20 cigarettes is prohibited.
