Specification-led quality control
Dimensions, thickness, construction, seals, rolls, appearance and packing are reviewed against the approved order requirements.
Production controls
The final control plan follows the approved product and order. No universal sampling frequency or AQL level is assumed here.
Inspection matrix
Methods shown are practical examples. The approved specification determines which checkpoints and tolerances apply to the order.
| Checkpoint | Example method | Recorded field | When applicable |
|---|---|---|---|
| Finished dimensions | Tape or approved measuring tool | Width, gusset, length and opening | All custom bags and covers |
| Film thickness | Micrometer | Target, tolerance and measured range | When included in the control planThe sanitized example used five recorded points per roll; the approved order plan controls the actual method. |
| Seal integrity | Manual pull or agreed test method | Seal area and observed result | Heat-sealed constructions |
| Visual condition | Controlled visual inspection | Holes, tears, gels, spots, contamination and print | All products, with relevant criteria selected |
| Perforation and roll | Tear, count, winding and core review | Bag count, core and roll condition | Bags or sheets supplied on roll |
| Packing and labeling | Count and label comparison | Quantity, label fields and packing method | Finished-lot release |
Evidence boundaries
Public evidence is kept close to its source and purpose. A photo, sample COA or certificate is not treated as proof of unrelated results.
Real inspection example
Sanitized Sample Record
| Approved specification | Recorded example |
|---|---|
| Product | Large clear mattress bag |
| Dimensions | 1,600 + 2 × 250 × 2,600 mm |
| Thickness target | 70 μm, ±10% |
| Recorded range | 67–72 μm |
| Seal observation | No visible break under the sample manual pull check |
| Visual observation | Example result recorded as pass |
This is one sanitized example record. It does not represent every product, order or production lot.

Buyer questions
No. It is one sanitized example showing how selected specification fields and observed results can be recorded. The applicable control plan, tolerance and release record are confirmed for each product and order.
Yes, when the requirement is defined before quotation and production approval. Share the critical dimensions, tolerance, test method, sampling expectation and documents you need so feasibility can be reviewed.
Confirm the measurement convention, critical dimensions and tolerances, thickness target, construction details, visual criteria, packing method and any buyer-specific record format. Roll, perforation, print and labeling fields should be added when relevant.
Buyers can request a product specification, a relevant sanitized inspection example and the current controlled certificate document. Availability is checked against the requested product before release.
Build the control plan
Send the critical product, measurement and document requirements before quotation so the closest workable inspection approach can be reviewed.
