Recycled Food and Beverage Cartons as a Replacement for Declining Traditional Feedstock in Molded Pulp Production, TAPPICon25

Cartons are a type of food and beverage packaging available in two forms: shelf-stable cartons (also known as aseptic cartons) and refrigerated cartons (gable top cartons). Cartons are primarily composed of paperboard to which fine layers of polyethylene are added. Shelf-stable cartons also contain a thin layer of aluminum.

Aseptic cartons are composed of on average 74% fibre, 22% polyethylene and 4% aluminum. Shelfstable cartons are used to hold juice, milk, plant- or grain-based milk, soup, broth and wine.

Refrigerated cartons are made up of approximately 80% fibre and 20% polyethylene. Refrigerated cartons are used to hold milk, juice, cream, egg substitutes, plant- and grain-based milks.

The fibrous material used in cartons in North America is kraft pulp for gable top cartons and, for aseptic cartons, a mixture of mostly kraft pulp and some CTMP (chemi-thermomechanical process) pulp1.

The Carton Council of Canada (CCC) is a coalition of carton manufacturers2 working together to deliver long-term solutions to help increase carton collection and recycling in Canada. This work includes developing new markets for end-of-life cartons.
