The Packaging Mills Association of Canada (PMAC) represents producers of packaging papers and boards used in the manufacturing
of paper-based packaging products.
PMAC members produce boxboard used, for example, to package consumer products; linerboard and medium used to fabricate corrugated
shipping containers; and kraft papers used in the manufacturing of all types of bags and sacks, as well as in a host of speciality
applications.
PMAC's mandate is to work on issues that are of concern to Canadian manufacturers of packaging papers and boards, as well as to their
customers worldwide. PMAC also carries out statistical and market research work that can be most efficiently carried out by one
industry group.
PMAC makes every effort to ensure that its activities do not contravene the provisions of competition or anti-trust laws of countries
with which its members trade, in particular those of the United States, Canada, and the European Union.

packaging materials. They can be converted into a wide variety of products such as grocers' bag, envelopes, multiwall sacks,
tire wraps, butchers' wraps, etc.
