Industrial Film

Ralston manufactures industrial film in both Alberta and Ontario. With film extruders and dies capable of supplying wide width and extra long jumbo rolls, we produce quality film products that meet many industrial applications across the country. From lining tractor trailers to protecting industrial machinery and hundreds of uses in-between, our film is extra tough and durable.

We also produce a wide variety of government approved construction films, made from virgin resins and UV resistance masterbatch. We’re committed to this market and were the first company in Canada to get accreditation with CGSB.

Industrial Garbage Bags

Ralston was a pioneer in the garbage bag market, manufacturing our first products in the early 1960’s. Since then, we have expanded our product line to include the widest variety of products manufactured by any company in the country.

We take our position as a market leader very seriously. We were the first in Canada to introduce linear low density resin, the first to introduce an anti-bacterial additive, the first to obtain Ecologo certification for the use of post-consumer film, the first to offer one-at-a-time bag dispensing, the first to introduce degradable film, the first to introduce certified compostable bio-resins.

Retail Products

Ralston has been involved in Consumer markets since we first began producing polyethylene plastic film over 50 years ago. We now offer a complete assortment of traditional garbage bag products under the Supersak brand including kitchen, outdoor, drawstring.

We also specialize in the growing market for recycling bags – transparent blue for dry recyclables, clear yard waste and transparent green for kitchen organics. Besides our own brand, we are one of the largest Canadian suppliers of private label bags and food cling wrap, marketed by an assortment of food store and mass merchandiser retailers in the country.

Our involvement in the retail market also includes producing clear plastic drop sheets and tarps to hardware and paint stores across Canada. We offer our own Cover-It brand or private label products.

Biosak Compostable Bags and Film

Ralston has been a pioneer in developing the new and growing market for certified compostable bioplastics in Canada. In recognizing that the marketplace was demanding new solutions for solid waste disposal management, we were the first Canadian company to produce certified compostable bags. This material, marketed under the Biosak brand, facilitates the collection of organic waste and is now sold through traditional retail outlets from coast-to-coast.

We have also launched an industrial line of Biosak bags, packed in large quantities, for use in the growing Institutional, Commercial and Food service marketplaces.

All these compostable products are certified by both Canada’s BNQ certification program and by the Biodegradable Product Institute in the United States. Biosak meets all the requirements of ASTM D6400-04 and the BNQ 0017-088.
