Quick answer: Pouch-grade nonwoven is a functional component, not generic paper. Its basis weight, fibers, bonding system, pore structure, thickness, seal window and roll consistency affect strength, release, mouthfeel and machine yield. Buyers should approve a material specification and finished-pouch performance rather than selecting fabric by GSM alone.
What buyers need to understand
GSM describes mass per area but does not fully predict softness or barrier behavior. Two materials at the same GSM may use different fibers and bonding systems. Confirm thickness, tensile strength, elongation, porosity, extractables information and food-contact suitability for the destination market.
How to control the risk
Run seal-window trials at intended speed and fill conditions. Check powder contamination in seams, burst or peel behavior, edge softness, wet strength, leakage, swelling and stability. Require supplier change notification for fibers, binder, manufacturing site and critical process changes.
Information to request from a supplier
| Area | Buyer evidence |
|---|---|
| Specification | Identity, dimensions, materials, tolerances and revision |
| Method | Sampling, equipment, conditions, units and acceptance criteria |
| Quality system | Lot records, deviations, CAPA and change notification |
| Commercial | MOQ, lead time, responsibilities and replacement terms |
Common mistakes
- Using a generic certificate without matching the finished lot
- Approving artwork before classification and specifications
- Comparing suppliers using different scopes or test methods
- Ignoring transport, consumer opening and shelf-life conditions
Procurement checklist
- Define the destination market and intended adult consumer.
- Approve formula, pouch, packaging and test specifications by revision.
- Require traceability, change control, release documentation and retained samples.
- Validate commercial-scale product in final packaging through shelf life.
Frequently asked questions
Can a sales sample replace a written specification?
No. A sample is useful for evaluation, but measurable tolerances and methods are needed for repeat production.
Should requirements be checked before artwork?
Yes. Classification, formula, count, warnings and responsible-party information should be settled before print approval.
How often should the file be reviewed?
Review after formula, supplier, process, packaging, claim or destination-market changes and at planned intervals.
