How should packaging adhesion be tested?
Select a method that reflects substrate, adhesive, cure time, temperature, load and failure mode, then define measurable acceptance criteria.

Checklist
Quality evidence to define before production
- Adhesive compatibility
- Test method
- Storage condition
- Inspection plan
- Target quantity and SKU allocation
- Approval sample and decision owner
- Required date and Mainland China delivery point
- Change and repeat-order record
Quality control
Four elements of an auditable inspection plan
Adhesive compatibility
Match adhesive to surface energy, coating, temperature, load and ageing; initial tack alone does not prove long-term performance.
Test method
Name the method, conditioning, equipment, units and pass criteria; words such as strong or durable are not measurable specifications.
Storage condition
Set temperature, humidity, stacking, sunlight, odour and shelf-time limits for materials and finished packaging.
Inspection plan
Define checkpoints, sample size, measurement tools, defect photos and release authority before production starts.
Execution method
Four actions from RFQ to production
Translate expectations into criteria
Use dimensions, tolerances, test methods and defect photographs.
Inspect at the right stages
Place controls at incoming material, first article, in-process and final release as risk requires.
Record traceable results
Identify lot, SKU, sample size, inspector, tools, findings and disposition.
Close corrective actions
Contain affected stock, verify root cause and confirm the fix before repeat release.
FAQ
Questions buyers often ask
How should packaging adhesion be tested?
Select a method that reflects substrate, adhesive, cure time, temperature, load and failure mode, then define measurable acceptance criteria.
What should be written in the specification?
At minimum, define Adhesive compatibility, Test method, Storage condition, Inspection plan, 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.
