Absolutely! Food – Packaging Boxboards

Boxboard packaging for food  

Introducing the first boxboard product for the Food Industry

Technical properties
Absolutely! Food is the first product of its type developed specifically for the Food Industry. Absolutely! Food has passed all Health Canada, Canadian Food Inspection Agency and FDA requirements for direct food contact. Strathcona Paper is the only recycled boxboard manufacturer to have received direct food contact accreditation by a Canadian authority.

Absolutely! Food is manufactured from 100% post-use recycled waste paper fibres. Approximately 65% of this post-use waste paper is defined as post-consumer material and 35% is defined as industrial scrap.

Absolutely! Food features a double clay coated surface and a light back liner, a colour preferred by food manufacturers and the consumers of their products. It is an ideal substrate for a wide range of food packaging applications where the appearance of the back liner is of importance. The most common include frozen and dried food packaging, bakery cartons and away-from-home food packaging.

Absolutely! Food is a denser, stiffer, brighter and higher plybond grade of food packaging boxboard. These positive boxboard properties, verified by the Recycled Paperboard Technical Association (RPTA), are what differentiate Absolutely! Food in the market.

Absolutely! Food is in compliance for direct food contact under the regulatory frameworks of the US Federal Food and Drug Administration Act (FDA), the California EPA Proposition 65 and the Canadian Food Inspection Agency. Absolutely! Food also complies with the provisions of the model state law CONEG, for heavy metal content. Metal detection capabilities to a particle size of 1.0mm are available on sheeted stock.

Product Structure

Absolutely! Food is a multi-ply sheet with a double clay coating applied over a top liner of recycled pulp substitute fibres (e.g., computer print out paper, sorted office waste paper) with a recycled filler fibre base. The filler fibre is comprised of double lined kraft, old corrugated cartons, boxboard and newsprint. In addition, Absolutely! Food can be produced with an application of special biodegradable sizing agent to provide moisture resistance to the boxboard.
