Coated Food Box Claim FAQ
Can a Coated Paper Food Box Be Called Plastic-Free?
A buyer guide to dry coating composition, barriers, adhesives, windows, food contact and substantiation of plastic-free claims.
The short answer: not without complete composition and claim evidence
A coated paper box is not automatically plastic-free because the coating is water-based or the structure is mostly fibre. Buyers must identify the dry coating and every other component, define claim scope and check target-market rules.
Why does water-based not mean plastic-free?
Water may carry polymer binders or barrier materials during application and then evaporate. The dry coating composition, not the carrier name, determines material content.
Does a thin coating need to be included?
Do not ignore it. Even a low coat weight can be intentionally added and functionally important. Claim rules may not provide a universal de minimis threshold.
What other components should be checked?
Review inks, overprint varnish, heat-seal layers, side-seam adhesive, window film, liner, label, tape and any transport bag supplied with the box.
Can a mineral or bio-based coating support the claim?
Material origin alone is insufficient. Exact binders, additives and the definition used for the claim must be verified. Bio-based does not automatically mean non-plastic.
Does plastic-free mean the box is food-contact compliant?
No. Food-contact safety depends on exact materials, intended food, time, temperature, migration and applicable law. Environmental claim evidence is separate.
Does plastic-free mean recyclable?
No. Recyclability depends on the finished pack and the collection, sorting and mill systems in the destination market.
Does it mean biodegradable, compostable or PFAS-free?
No. Each is a separate claim requiring its own definition, evidence and qualifications.
Can the claim cover only the main carton?
Only if the scope is clear and not misleading. Consumers should understand whether liners, windows, labels and supplied accessories are excluded.
What wording is safer when evidence is limited?
Use a narrow factual statement, such as no plastic film lamination, only when verified. Avoid implying that all coatings, adhesives and accessories are plastic-free.
What should buyers request?
Request a complete bill of materials, dry coating composition or supplier declaration, component weights, food-contact documents, claim jurisdiction, approved wording and change control.
