B2B procurement · Buyer guide
A pocket tissue supplier should identify the actual packaging film and measure its thickness at agreed positions before pack approval. Compare rolls and production lots, then run the finished mini-pack through sealing, opening and handling checks. A nominal gauge on a film datasheet does not show local thin spots or prove that a filled pack will survive distribution.
This is a packaging-material acceptance plan, not a Sansheng film-gauge result. Mechanical scanning under ISO 4593:1993 applies to suitable plastic film, not embossed film, and does not set a pocket-pack limit.

Direct answer
A pocket tissue supplier should identify the actual packaging film and measure its thickness at agreed positions before pack approval. Compare rolls and production lots, then run the finished mini-pack through sealing, opening and handling checks. A nominal gauge on a film datasheet does not show local thin spots or prove that a filled pack will survive distribution.
Lock the film construction before sampling
Request the film grade, structure, supplier, nominal gauge, print or coating treatment, and whether the material is embossed. Keep the approved film roll and finished mini-pack together. The pocket tissue supplier should not compare an unprinted laboratory strip with a different printed production film and attribute every difference to gauge.
Map thickness across rolls and lots
Select film from several roll positions and manufacturing lots. Mark measurement points across the web and along its length, and report individual values, minimum, range and instrument resolution. ISO 4593:1993 specifies mechanical scanning for appropriate plastic film or sheeting; it excludes embossed film. Agree an alternative method if the actual wrap falls outside its scope.
Check the finished pack
Use the measured film to make packs with the final tissue count, seal pattern and opening feature. Inspect weak areas near folds and seams, then test the pack against its separate seal, opening and transit criteria. A thick film is not automatically a better pack: stiffness and seam behavior can change. Record the film roll and mini-pack IDs together.
Turn the range into a release rule
Set minimum and maximum film gauge from signed production-intent samples, not a generic catalogue claim. Define how many readings, which locations and what to do with an outlier. Reapprove after film supplier, resin, embossing, print or sealing settings change. Keep the raw measurement map with the purchase specification.
Buyer comparison record
| Check | Record | Buyer purpose |
|---|---|---|
| Film identity | Grade, roll and treatment | Prevent mixed constructions |
| Gauge map | Individual readings and positions | Detect local variation |
| Finished pack | Seal and opening observations | Check conversion effect |
| Disposition | Range and retest rule | Make release repeatable |
What should buyers ask the pocket tissue supplier?
- Actual film structure and approved roll sample
- Measurement method and across-web/length positions
- Raw gauge readings across lots
- Finished-pack trial and change-notification rule
Send the pocket tissue supplier your intended use, destination and required acceptance decision.

Questions buyers also ask
Does the nominal film gauge prove every pack is consistent?
No. Ask for a sampling map and individual readings from the production film.
Does ISO 4593 apply to embossed film?
No. Its stated scope excludes embossed film; agree a suitable method for that construction.
Can gauge replace a seal test?
No. Thickness and finished-seal performance answer different questions.
