Fiber structure
Uniform web formation supports cleaner appearance, soft hand feel and stable converting behavior during pouch production.
Technical Data
Typical Technical Data for Pouch-Grade Nonwoven Fabric
Use this TDS-style overview to review key parameters before sample testing, machine matching and bulk slit-roll procurement.
Typical Technical Data
A TDS-style parameter table helps buyers quickly review basis weight, pore size, air permeability, slit range and available supporting documents.
Material Type
Pouch-grade nonwoven fabric for heat-sealed pouch production and machine trial evaluation
Basis Weight
12–38 gsm customizable, with common range 25–35 gsm
Pore Size
Typical 70–90 μm, adjustable according to formula target
Air Permeability
500–1200 L/m²/s
Fiber Shedding
Grade 0–1
Slit Width
29–33 mm commonly used, mainly 31/32 mm; other slit widths to be confirmed
Roll Length
Usually 700–800 m per slit-roll, customizable
Customization
GSM, softness, whiteness, sealing profile and nonwoven composition ratio can be fine-tuned
Sealing Compatibility
Heat sealing, intermittent sealing and continuous sealing support; other sealing systems should be confirmed by machine trial.
Documents
TDS, COA and MSDS available; food-contact, ISO, CE or other compliance files to be confirmed by product and project scope
Material Science
Fiber Structure, Sealing Profile, Air Permeability and Low Fiber Shedding
This section helps buyers understand the material science behind pouch performance, not just product images.
Sealing profile
Different grades can be tuned for stable sealing behavior across flat-jaw, intermittent and continuous line configurations.
Air permeability
Breathability and pore structure can be aligned to product positioning, powder release expectations and pouch feel requirements.
Low shedding
Low fiber shedding helps support cleaner pouch presentation, more consistent line behavior and better buyer confidence.
