MSN-7B Heat-Sealable Oral Pouch Nonwoven
A 32 gsm / 34 gsm nonwoven material platform for oral pouch sample review and production-line qualification. Performance should be validated against the target application, pouch format, fill, equipment and process conditions.
Evidence status
Separate controlled product data from qualification assumptions
34 gsm data
Current manufacturer-issued values are published below with their current scope.
32 gsm performance
Available for sample review; do not transfer all 34 gsm values by assumption.
SGS support
Scope-specific 2025 reports cover the named material/sample and must be read by model, date and conclusion type.
Method references
Two TDS method references require verification against original test records; no replacement method number is guessed.
Current 34 gsm manufacturer TDS values
Numeric values below reproduce the current manufacturer-issued 34 gsm limits. Where the existing TDS method reference is under review, the website intentionally does not present it as a validated test method.
| Parameter | Current 34 gsm value | Method / status |
|---|---|---|
| Model convention | MSN-7B-34-XX-YY | XX = nominal width; YY = nominal roll length |
| Basis weight | 34 ± 2 g/m² | ISO 9073-1 |
| Thickness | 0.16–0.20 mm | ISO 9073-2 |
| Tensile strength — MD | ≥45 N / 5 cm | ISO 9073-3 |
| Tensile strength — CD | ≥5.5 N / 5 cm | Method reference under review |
| Heat seal strength | ≥13 N / 5 cm | Method reference under review |
| Recommended shelf life | 24 months | Under appropriate storage conditions |
| Basis-weight options | 32 / 34 gsm | Match the option to its current qualification documents |
Where MSN-7B enters the qualification process
Converting
Nominal width, roll format, feeding and line stability should be confirmed on the target equipment.
Sealing
Use machine-specific trial settings and acceptance criteria; do not assume one universal temperature or dial position.
Finished pouch
Review powder retention, wet integrity, appearance, mouthfeel, handling and consistency with the actual fill system.
Current documentation path
- MSDS and manufacturer-issued food-contact / material statements.
- 2025 SGS report recording a Pass for FDA 21 CFR 176.170 chloroform-soluble extractives for the tested MSN-7B sample.
- Separate 2025 SGS ingredient review with reference to FDA 21 CFR 175.105; not a blanket FDA approval.
- Historical evidence is kept separate from the current MSN-7B evidence set.
