Airlaid Napkins · B2B procurement guide
Ask an airlaid napkin supplier to compare production-representative colored napkins with an agreed reference under a defined wet-contact protocol. Specify the liquid, contact surface, duration, pressure, conditioning and assessment method before samples are tested. Approve each relevant color and construction separately; a dry visual match cannot establish wet color fastness.
For foodservice distributors and private-label buyers of dyed airlaid dinner napkins. This guide separates a practical purchasing screen from laboratory evaluation and does not assign a universal pass grade.
Send the product revision, intended use, order quantity, destination and the approval question you need to resolve. A useful quotation starts with those details.

Reusable procurement data
Which contact conditions should the buyer define?
Start with the actual use: a damp napkin against hands, a white table surface or food-contact conditions. These are different exposures. Record the selected contact material and whether the test concerns a dyed substrate or a printed area. An airlaid napkin supplier should not substitute a convenient liquid for the agreed exposure without recording that change. Keep an unused contact material as a blank so contamination can be recognized.
Use the same specimen dimensions and contact arrangement for the reference and candidate. Do not turn a casual wipe on a wet finger into a quantitative certificate. Where a formal method is required, have a qualified laboratory select the applicable procedure and explain its scope.
Dry appearance and wet transfer are separate approvals
A napkin may match the approved shade when dry yet leave color on a contact surface. Conversely, a visible shade difference does not by itself demonstrate dye transfer. Keep separate records for appearance and staining. Compare the contact material after exposure, rather than judging only how much color seems to remain in the napkin.
The published DIN listing for EN 646 concerns color fastness of dyed paper and board intended for food contact. Its applicability to the precise airlaid construction needs laboratory confirmation. A new draft edition is not automatically an adopted replacement. The airlaid napkin supplier should identify the method edition used in any report.
How should samples represent the order?
Identify color code, fiber and bonding construction, basis weight, fold, lot and packaging. Sample more than the neat loose sheet sent for initial sales approval. Include packed material and decide whether transport or storage conditioning belongs in the program. Changes in dye, binder or finishing may justify a fresh assessment even when the commercial color name stays unchanged.
Photograph the sample and contact material under controlled lighting, but retain the physical references because photographs can shift color. Have the airlaid napkin supplier record any deviation from the agreed preparation. One acceptable specimen should not be treated as permission to ignore inconsistent results elsewhere in the lot.
Agree the decision before seeing the result
Define who evaluates staining, what reference or rating system they use, how borderline observations are handled and when an independent laboratory is needed. The buyer should not invent a numerical limit after seeing a disappointing sample. Record the disposition of the affected lot: accept, hold, investigate or replace.
Request separate evidence for chemical or food-contact claims. A wet-transfer screen is not a complete safety assessment. An airlaid napkin supplier report should identify what was tested, rather than applying a favorable result to every shade, print or future production batch.
Airlaid napkin supplier approval checklist
| Control point | What to record | Buyer purpose |
|---|---|---|
| Construction | Dyed base or printed area | Confirm applicable method |
| Contact | Liquid, surface, time and pressure | Make trials comparable |
| Assessment | Reference and rating rule | Avoid subjective release |
| Traceability | Color, lot and pack identity | Limit approval scope |
Put these fields in the RFQ
For airlaid napkin supplier discussions, keep the following fields with the controlled specification rather than scattering them across messages.
- Color and construction identifiers
- Intended use and contact conditions
- Specimen preparation and laboratory method, if required
- Sampling plan and agreed staining limit
- Retained references and change-control owner
For related formats, review paper napkin supply options before comparing quotations.
Questions buyers also ask
Does no visible staining mean food-contact compliance?
No. Visible staining is only one observation. The applicable material assessment and destination requirements remain separate.
Can one tested color approve the whole range?
Do not assume so. The evidence owner must justify any grouping based on the actual formulations and production controls.
Sources and scope notes
- DIN EN 646:2019-02 — scope of color-fastness testing. Supports: The published listing identifies a color-fastness method for dyed food-contact paper and board. Limit: It does not provide a universal buyer limit or certify airlaid or skin-contact products. Confirm the applicable adopted edition with the laboratory; a 2026 draft is not treated here as a final replacement.
- ASQ — Supplier Quality. Supports: A supplier-quality framework for clear requirements, evaluation and improvement. Limit: It supplies no product-specific acceptance threshold and does not verify Sansheng production results.
