Design for recyclability means choosing materials, inks, adhesives and structures so a package can be collected, sorted and reprocessed into usable feedstock, and a useful design principle is to favour monomaterials. Producer responsibility guidance such as ÉEQ’s ecodesign checklist and Canadian environmental-claims guidance supports making environmental claims with verifiable evidence. For paper shopping bags, these design choices can help support recyclability.
TL;DR:
- Paper bags and corrugated boxes have recycling access for 96% of Canadian residents, but claims still depend on compatible design and verifiable evidence.
- Choose one material or separable parts, inks made with water, and adhesives that dissolve in water; avoid carbon black pigment, PVC, and heavy coatings.
- Require standardized repulpability tests, mill run data, and recycled content documents from suppliers before approving production or making claims.
- Proposed federal rules would restrict recyclability labels and chasing arrows on plastics unless producers verify recyclability, local access, and end markets.

How collection, sorting, and processing decide recyclability
A package’s recyclability depends on collection, sorting and processing. Design failures show up at each one, and the label on the material rarely overrides them.
- Collection: the material must be accepted in curbside or depot programs where the product is sold. Access matters as much as the resin or fiber type.
- Sorting: Sorting systems separate materials, and small mixed-material components and carbon-black pigments can create recycling challenges.
- Processing: adhesives that do not dissolve, heavy coatings and laminated layers become contaminants that lower the quality of recycled output or cause entire batches to be rejected.
- End markets: a material with no buyer for its recovered output is not recycled in practice, however recyclable it looks on paper.
Mixed-material components can complicate recycling, particularly when their layers cannot be separated.
Cross-material principles: monomaterials, inks, adhesives, and separability
Monomaterials come first. A multilayer laminate can combine materials that are processed differently, complicating recycling. Canadian producer responsibility organizations are now aligning their ecodesign guidance, prioritizing monomaterials and discouraging components such as PVC and heavy coatings.
- Specify water-based inks and water-soluble adhesives, and keep adhesive quantities to the minimum that holds the construction.
- Avoid carbon-black pigments and large-area coatings, which interfere with sorting and processing. A design-for-recycling factsheet flags the same problem for small mixed-material components.
- Choose closures that separate cleanly or, better, closures made from the same material as the body.
- Keep labels simple and small, and avoid detachable parts that can get lost in the stream.
Pro Tip: Ask every supplier for written test data and stated tolerances for each material and finish, then keep those documents with the spec so your claims can be defended later.
Paper and paperboard: repulpability, inks, and testing
Paper is the strongest starting point. In Canada, 96% of residents have access to recycling for paper bags and corrugated boxes, and 94% have access for boxboard cartons.
Access to paper bag and corrugated box recycling reaches 96% of Canadian residents. That coverage can support an unqualified recyclable claim for paper packaging, provided the design and claim meet applicable guidance.
PPEC guidance makes the same point for paper packaging generally. What to specify:
- Water-based inks and water-soluble adhesives, avoiding carbon-black pigments and heavy coatings.
- Standardized repulpability testing, which is the accepted way to validate compatibility with recycling infrastructure.
- Mill-run data and recycled-content documentation from the supplier. Our guidance on requiring mill run data explains what to ask for.
When plastic is unavoidable: resin, pigment, and labelling
Some components, such as a window film or a closure, may need to be plastic. Check whether local recycling systems can handle the specific material, and consider avoiding PVC and other components without a suitable recycling channel.
- Choose light or natural colors where function allows, since carbon-black pigment can prevent optical sorters from identifying the item.
- Treat recyclability claims on plastic as something you must prove. Federal labelling rules would bar recyclability claims and the chasing-arrows symbol unless producers have assessed recyclability and met access and end-market criteria.
Extended producer responsibility raises the same demand for evidence. The more documentation you hold, the easier it is to defend a claim.
Labelling proposals and producer responsibility that shape specs
Federal proposals under CEPA would add recyclability labelling rules, including specified label formats, QR-code information, and recycled-content requirements. Vague terms are a target.
Prohibitions on vague terms such as “degradable” or “biodegradable” without certification are part of the proposal.
- Existing environmental claims already fall under Competition Bureau guidelines, where recyclable claims must rest on verifiable evidence.
- Five Canadian producer responsibility organizations announced steps toward harmonized ecodesign guidelines intended to support producers across provinces.
- Keep dated records of materials, test results and supplier declarations now. Our overview of packaging EPR duties shows how this changes procurement.
A spec checklist for design and sourcing teams
- Confirm the bag or package is a monomaterial, or that every component is separable.
- Confirm water-based inks and water-soluble adhesives, with no carbon-black pigment.
- Set label area limits and placement so labels do not cover most of the surface.
- Verify closures and handles separate cleanly or match the body material.
- Collect repulpability test reports and recycled-content certificates.
- Confirm acceptance of the material in each province where it will be sold.
Request mill-run data, proof of recycled content, quality assurance results and compatibility test reports from every supplier before approving a design.
Pro Tip: Write recyclability evidence into your RFP and make it a pre-production signoff item, so documents arrive before the first run rather than after a claim is questioned.
Where to find the definitive guidance and test standards
Each resource answers a different question.
- ÉEQ Packaging Recyclability Guidelines: material-specific design rules.
- APR Design® Guide: technical plastic packaging design guidance.
- PPEC guidance: claims and access thresholds for paper packaging.
- ISO 14021: principles for self-declared environmental claims.
- Repulpability test methods: validation for fiber compatibility.
Our perspective on recyclable retail paper packaging
Design choices can affect recyclability, so it is useful to consider conversion questions early. For paper shopping bags, discuss material choices, print requirements and quality assurance needs with Gather Packaging. Discuss with Gather Packaging what test documents may be needed for labelling and producer responsibility reporting while the design is still being developed.

FAQ
What does design for recyclability mean in packaging?
It means designing so a package can be collected, sorted and reprocessed into usable material. In practice, that can mean considering monomaterials, compatible inks and adhesives, and components that may complicate recycling.
Are paper bags easy to recycle in Canada?
Yes, when designed well. Most residents have access to paper bag recycling, and water-based inks, water-soluble adhesives and light coatings keep the bag repulpable.
Can I put the chasing-arrows symbol on my packaging?
Only with verifiable evidence behind it. Competition Bureau guidance requires recyclable claims to be supported, and proposed federal rules would restrict the symbol on plastics unless recyclability has been assessed.
Which inks and adhesives are best for recyclable paper?
Water-based inks and water-soluble adhesives. Avoid carbon-black pigments and heavy coatings, then confirm compatibility with a standardized repulpability test.
