SMS Nonwoven Composite Structure — Spunbond Meltblown India
SMS nonwoven composite structure combines spunbond strength with meltblown filtration in a single laminated fabric. Favourite Fab supplies SMS nonwoven as an upstream raw material to hygiene product manufacturers, surgical gown makers, and industrial fabric converters across India and globally. This guide explains the SMS composite structure, available specifications, and how to source the right grade for your production line.
What Is SMS Nonwoven Composite Structure
SMS stands for Spunbond-Meltblown-Spunbond. It is a three-layer laminated nonwoven fabric where two spunbond outer layers sandwich a meltblown core layer. The spunbond layers provide tensile strength, tear resistance, and softness. The meltblown middle layer delivers barrier protection against fluids, aerosols, and microorganisms.
The three layers are thermally bonded together in a single inline process or laminated offline. The resulting fabric combines the mechanical properties of spunbond with the filtration and barrier performance of meltblown — without adhesives or chemical binders.
SMMS (Spunbond-Meltblown-Meltblown-Spunbond) and SMMMS variants increase barrier performance by adding additional meltblown layers. Basis weight, layer ratio, and bonding pattern determine final fabric performance.

Applications in Hygiene and Medical Manufacturing
SMS nonwoven composite structure is the primary substrate for single-use protective products. Manufacturers cut and sew or ultrasonically weld this raw material into finished items.
- Surgical gowns and drapes: 40–60 gsm SMS provides AAMI Level 2–3 barrier protection against blood and bodily fluids.
- Surgical face masks: 15–20 gsm SMS outer and inner layers surround the meltblown filtration core. See spunbond for face masks for the spunbond layer specification.
- Disposable coveralls and shoe covers: 20–30 gsm SMS balances protection with breathability for industrial hygiene applications.
- Baby diaper back sheets: soft-finish SMS provides a cloth-like feel with adequate barrier properties.
- Feminine hygiene packaging layers: light SMS barriers in sanitary napkin and panty liner construction.
- Sterilisation wrap: validated SMS pouches maintain sterile barrier for medical instruments.
SMS vs SMMS vs SMMMS — Choosing the Right Composite
SMS nonwoven composite structure choice depends on your required hydrostatic head, BFE target, and cost per unit. Adding M layers raises barrier performance but also increases basis weight and material cost. For most hygiene applications, SMS at 20–25 gsm is sufficient. Surgical gown manufacturers typically specify SMMS at 40–60 gsm for AAMI Level 3 compliance.

Frequently Asked Questions
What is SMS nonwoven composite structure used for in hygiene manufacturing?
SMS nonwoven is used as the primary barrier fabric in surgical gowns, face masks, coveralls, and hygiene packaging. The spunbond outer layers provide mechanical durability and softness while the meltblown core filters particles and blocks fluids. Hygiene manufacturers source SMS as a raw material roll and convert it on their own cutting and assembly lines.
What is the difference between SMS and SMMS nonwoven?
SMMS adds a second meltblown layer between the two spunbond outer layers, increasing hydrostatic head resistance and BFE performance. SMS suits hygiene and light protective applications. SMMS and SMMMS are specified for surgical gowns requiring AAMI Level 3–4 barrier certification. Both configurations are available from Favourite Fab.
Does SMS nonwoven meet AAMI Level certification requirements?
Yes. Favourite Fab’s medical-grade SMS and SMMS composites are produced to meet AAMI PB70 Level 1–4 hydrostatic head requirements. Test reports are available on request. Customers sourcing material for AAMI-certified end products should specify their required barrier level and we will confirm the correct basis weight and configuration.
Can I order SMS nonwoven in a custom colour for my brand?
Yes. Standard stock colours are white, blue, and green. Custom colours are available for orders above the custom colour MOQ threshold. Masterbatch colour matching is performed in-house. Share your Pantone reference and we will provide a colour sample before committing to full production.
What is the minimum order quantity for SMS nonwoven fabric?
Standard MOQ is 500 kg for white-grade SMS. Medical-grade SMMS in specific widths may require 1,000 kg minimum due to setup. First-time sample orders of 50–100 kg are available for qualification testing. Contact sale@favouritehub.com with your specification for a confirmed MOQ and lead time.
How is SMS nonwoven composite structure packaged for export?
Rolls are wrapped in polyethylene moisture-barrier film and loaded on export-grade pallets. Each pallet is stretch-wrapped and labelled with GSM, width, roll number, and production date. Favourite Fab provides full export documentation including packing lists, invoices, and test certificates aligned with your country’s import requirements.
