How should biodegradable packaging claims be verified?
A biodegradable or compostable claim needs a defined material, test standard, conditions, certification scope and disposal route; the words alone are not evidence.

Checklist
Material facts to request and approve
- Claim evidence
- Document scope
- Material specification
- Required markings
- Target quantity and SKU allocation
- Approval sample and decision owner
- Required date and Mainland China delivery point
- Change and repeat-order record
Material evaluation
Four checks before approving the material
Claim evidence
Tie recycled, biodegradable, compostable or reduced-plastic statements to a defined product, method and supporting document.
Document scope
Check certificate holder, site address, standard, product scope, issue body and validity instead of accepting a logo or screenshot.
Material specification
Name the grade, composition, colour, surface and approved equivalent; a generic material name is rarely enough for repeat production.
Required markings
List mandatory text, symbols, languages, minimum size, placement and approval owner for each destination and channel.
Execution method
Four actions from RFQ to production
Define the application
Start from protection, forming, print, appearance and distribution needs.
Compare physical samples
Review representative material under agreed lighting and handling conditions.
Run process trials
Test printing, creasing, gluing, finishing and packing on the proposed build-up.
Freeze an approved specification
Record supplier, grade, weight, thickness, colour and permitted substitution rules.
FAQ
Questions buyers often ask
How should biodegradable packaging claims be verified?
A biodegradable or compostable claim needs a defined material, test standard, conditions, certification scope and disposal route; the words alone are not evidence.
What should be written in the specification?
At minimum, define Claim evidence, Document scope, Material specification, Required markings, then link quantity, sample, timing, inspection and the approved revision.
Is a physical sample needed?
A decision involving structure, material, colour, finish, assembly or use performance normally needs a physical sample matched to that question; a screen proof cannot approve everything.
Can the previous standard be reused for a repeat order?
Reuse a controlled standard only when files, material, structure, supply chain and use conditions remain unchanged. Record every change and decide whether resampling or reapproval is required.
