Quality begins with an approved specification
Testing is meaningful only when dimensions, thickness, material, tolerance and intended application are defined. Typical checks may include width and length, thickness readings, weight per piece, seal appearance, visual defects and practical loading tests.
Production versus laboratory tests
Routine factory checks and formal standardised laboratory tests are not the same. The quotation or quality plan should state which checks and documents are required.
Plastic-bag quality checks for buyer approval
A practical approval plan should connect every test to the packed product and handling risk. Dimensions, thickness, seal integrity, load performance, appearance and print should be checked against the signed specification.
Request a specification quoteBuyer checklist
- Measure width, length, gusset and thickness at defined points.
- Inspect seals for continuity, contamination and weak areas.
- Run load, drop or handling trials with the real packed product.
- Check print registration, rub resistance and colour reference.
- Retain an approved sample and record batch traceability.
Quick comparison
| Format or check | Specification | Typical purpose |
|---|---|---|
| Dimensions | Width, length and gusset | Calibrated scale or gauge |
| Thickness | Micron distribution | Thickness gauge |
| Seal integrity | Leaks and seal continuity | Burst, peel or practical load trial |
| Registration and rub resistance | Approved artwork and colour reference |

Frequently asked questions
What information should be sent before requesting a quotation?
Send the application, packed product, material preference, finished dimensions, thickness, construction, printing, quantity, packing and delivery city.
Should a production order be approved from a sample?
Yes. A signed sample or trial should represent the agreed material, dimensions, thickness, seal, appearance and print before repeat production.
Are online calculations final production specifications?
No. Calculators and guides provide estimates. Final values should be confirmed against the approved material, tooling, tolerances and production sample.
