Short answer: do not approve food packaging because a supplier calls it “biodegradable.” Ask what the claim applies to, under which disposal conditions, for which exact structure and with what current evidence. Then check food-contact use and pack performance separately.
Four claims that buyers should not treat as synonyms
| Claim | What it tells you | What it does not tell you |
|---|---|---|
| Bio-based | Some feedstock comes from renewable biological sources | It does not automatically prove compostability, biodegradability or recyclability |
| Biodegradable | A material can break down under stated conditions | It does not define the time, environment, complete package or local disposal route by itself |
| Compostable | The exact item is intended to meet stated composting conditions and evidence | Industrial and home composting are not interchangeable |
| Recyclable | The structure may fit a recycling route under stated conditions | Collection, sorting and local facility access still matter |
Ask for evidence tied to the complete structure
The print, adhesive, coating, sealant, zipper and label can change the claim. Request the document holder, exact grade or structure, scope, test method, date, validity, intended disposal environment and permission to use the claim. A report for one sample should not be applied to every SKU or the finished pack.
The US FTC Green Guides summary warns against broad, unqualified environmental claims and explains that compostable and recyclable claims need specific substantiation and qualification. Treat this as a claims check, not as product approval.
Food-contact review is a separate question
Environmental evidence does not replace food-contact review. Define the food type, contact conditions, temperature, storage time and which side of the structure contacts the product. The FDA’s packaging terms distinguish a food-contact substance, material and finished article; buyers should match supporting information to the intended use and complete offered structure.
Performance still has to work on the line
Before bulk production, check feeding, forming, sealing, print rub, puncture or tear behaviour and the barrier target that matters to the food. A structure that supports one environmental claim may still be unsuitable if it cannot protect the product or run reliably.
A buyer document checklist
- Exact layer build and thickness
- Claim wording you intend to print or publish
- Current certificate or test report, holder and validity
- Industrial or home disposal condition, where relevant
- Food type, contact temperature and storage conditions
- Machine, seal method and trial acceptance criteria
- Destination market and local labelling or disposal guidance
Use a claim that says exactly what you can prove
“Eco-friendly” is too broad to guide a purchase. A better claim names the material attribute, percentage or disposal condition and keeps the qualification close to the claim. If the evidence is incomplete, leave the claim off the artwork until it is resolved.
Send the structure and claim for review
For a paper-led route, review Bio-Based Paper Rollstock. To discuss a project, send the complete structure, packed food, intended claim, market, machine, seal conditions and required documents through the Specialty RFQ.
