Most product packaging is copyrighted; images where copyrighted product packaging constitutes a major aspect of the image are not allowed on Commons. Wikimedia Commons does not accept fair use of such images.
However, the following are allowed:
Images of packaging that does not include any copyrighted images or logos.
Images where copyrighted material is only a minor component (see Commons:De minimis).
Very old designs on which the copyright has expired (acceptable even if trademark rights persist; see Commons:Licensing for country-by-country rules on copyright expiration).
