3-Layer SMS Type 5/6 Nonwoven Coverall: High Breathability Polypropylene Barrier Engineered for Hazardous Particle and Chemical Liquid Splash Protection
Product Overview & Customization Capabilities
Xiamen Topmatched manufactures disposable SMS Type 5/6 coveralls wholesale for industrial safety distributors, healthcare procurement networks, chemical processing facilities, and commercial painting suppliers. Constructed from 3-layer SMS (Spunbond-Meltblown-Spunbond) nonwoven polypropylene, this protective garment balances breathable vapor transmission with filtration against hazardous dry particulates and light chemical aerosol sprays. The ergonomic hooded design incorporates an elasticated face opening, elastic waist, elastic wrists, and elastic ankles to ensure an impenetrable barrier over personal footwear and respirators. As a China OEM/ODM medical and industrial protective clothing supplier, we support custom fabric weight options (45 gsm to 65 gsm), custom colorways (white, blue, orange), private label chest logo printing, custom size grading (S through 3XL), and customized export outer carton packaging based on buyer tenders.

Quality Control & Certifications
Our ISO 13485 certified cleanroom manufacturing facilities enforce multi-stage quality control protocols to guarantee garment integrity across volume production runs. Every lot of raw SMS nonwoven fabric undergoes Hydrostatic Head liquid barrier testing and air permeability testing to verify vapor breathability alongside Type 5/6 filtration parameters. Zipper pull strength and seam tensile resistance are verified under automated electronic strength testing equipment. Garments are systematically inspected for stitching consistency, elastic retention at wrists and ankles, and adhesive seal alignment on front flap closures before automated folding, polybagging, and carton sealing.


Typical Application Scenarios
These disposable SMS Type 5/6 coveralls are engineered for heavy-duty protection across industrial and commercial work environments:
Industrial Chemical & Pharmaceutical Processing: Protecting operators against hazardous chemical dusts, powder handling, and light liquid splashes.
Automotive & Commercial Spray Painting: Preventing airborne paint overspray, aerosol mists, and lint contamination on pristine surfaces.
Construction & Insulation Installation: Shielding workers from airborne glass fibers, asbestos abatement debris, and masonry dusts.
Medical Cleanroom & Maintenance Work: Serving as a hygienic protective barrier in healthcare facility maintenance, sanitation, and infection control programs.
FAQ
Q1: How does the 3-layer SMS nonwoven fabric maintain liquid barrier protection while remaining breathable during physical labor?
A1: The inner meltblown layer acts as a dense web filtering liquid mists and hazardous particles, while dual outer spunbond layers allow heat and body moisture vapor to pass through, reducing heat stress during extended shifts.
Q2: Can we customize fabric weight and zip storm flap tape specifications for bulk municipal healthcare tenders?
A2: Yes, as a manufacturer we supply fabric weights from 45 gsm to 65 gsm and can integrate single or double self-adhesive tape strips over the zipper flap to meet exact procurement tender specifications.
Q3: Are these Type 5/6 protective coveralls anti-static treated for use in explosive chemical or dust-sensitive environments?
A3: Yes, garments pass EN1149-5 electrostatic dissipation standards, preventing static charge accumulation on the fabric surface to minimize spark risks in flammable vapor or combustible dust zones.
