B2B procurement · Buyer guide
An airlaid paper supplier should report grammage from a mapped set of specimens across the usable web width, not only one center sample or one roll average. Mark drive side, center and operator side, repeat the map along the running length, and retain the individual values. Compare any repeating lane with converting behavior. A GSM map identifies mass variation; it does not by itself identify binder chemistry or predict every downstream defect.
This guide is for airlaid parent rolls intended for conversion. A tissue-paper grammage standard may be informative, but the buyer must agree a method suitable for the specific airlaid construction.

Direct answer
An airlaid paper supplier should report grammage from a mapped set of specimens across the usable web width, not only one center sample or one roll average. Mark drive side, center and operator side, repeat the map along the running length, and retain the individual values. Compare any repeating lane with converting behavior. A GSM map identifies mass variation; it does not by itself identify binder chemistry or predict every downstream defect.
Map the usable width before cutting specimens
Identify roll number, nominal width, trim allowance, drive side and operator side. Take equal-area specimens from fixed cross-web positions, avoiding edge damage and splices unless those areas are the subject of the complaint. Repeat at separate roll positions. The airlaid paper supplier and converter should both keep the sampling diagram so a lane can be located later.
Keep every GSM reading
Condition and weigh specimens using an agreed grammage procedure and calibrated balance. ISO 12625-6:2016 specifies grammage measurement for tissue paper; confirm applicability before citing it as the airlaid contract method. Report individual values, location, mean and range. An acceptable average can hide a heavy edge and light center that destabilize a converting line.
Check whether variation repeats in production
Compare the same cross-web lane at the start, middle and end of the sampled roll. If a pattern persists, retain full-width strips and run a controlled slitting or folding trial at known settings. Record rejects by lane rather than attributing all waste to the parent roll. GSM differences may matter differently for printing, folding and absorbent use.
Specify a usable-width decision
Agree cross-web tolerance, allowable local variation, trim treatment and dispute sampling before the order. A narrow defect lane may have a different commercial effect from random full-width variation. Ask the airlaid paper supplier for the roll map, raw readings and the quantity of saleable material after any agreed trim.
Buyer comparison record
| Check | Record | Buyer purpose |
|---|---|---|
| Location | Drive, center, operator and length position | Find repeating lanes |
| Specimen | Area, conditioning and mass | Make GSM comparable |
| Readings | Each value plus range | Avoid hiding extremes |
| Conversion | Rejects by web lane | Link variation to actual yield |
What should buyers ask the airlaid paper supplier?
- Usable width, trim allowance and nominal GSM
- Cross-web and down-web sampling map
- Agreed grammage method and individual readings
- Tolerance and converting-trial disposition

Questions buyers also ask
Can one center specimen approve a full roll?
No. It cannot reveal an edge or cross-web lane that differs from the center.
Does GSM identify the cause of a streak?
No. It shows mass per area; root-cause work may require other physical or analytical checks.
Can the tissue ISO method automatically be applied to airlaid?
Check the standard’s scope and contract method against the exact airlaid construction before using it as the acceptance basis.
