Meltblown Nonwoven Fabric Material for Mask Production
Meltblown fabric is one type of pp spunbond nonwoven, is used as the key filter material for all kinds of masks.
Learn how we ensure you buy the right melt blown fabric:
Description
Meltblown farbic, has many varied names like meltblown cloth, meltblown nonwoven, and since it is one kind of special nonwoven or spundond, people also name it as spunbond melblown, melt blown cloth’s raw material is mainly polypropylene, the fiber diameter can reach 1 to 5 microns. It has many voids, fluffy structure, good wrinkle resistance, unique capillary structure of microfiber to increase the number of fibers per unit area, and surface area, so that the meltblown cloth has good filtration, shielding, heat insulation and oil absorption. Can be used for air and liquid filtration materials, isolation materials, absorbent materials, mask materials, warm materials, oil-absorbent materials and wiping cloth, etc.
The meltblown fabric we offer is for mask filter application use and has special specifications, which help the final mask can meet the requirements of varied standards.

3 ways to ensure & validate the quality
Adopts qualified electret masterbatch, which results in a long duration of the electrostatic adsorption capacity of the meltblown.
PFE test, BFE test, Synthetic blood penetration test, Differential pressure test, Breaking force test, Final mask testing;
Use the meltblown fabric on mask machines to validate whether meltblown fabric is suitable for long time production
*All tested samples will be processed under high temperature and low temperature (high temperature 70 degrees, low temperature minus 30 degrees), simulating the aging of natural time for 1 year.

Meltblown Package: Check how we pack the meltblown fabric to the maximum protection:
Only by protected in a certain way, after days of transportation(actually weeks), you can get the meltblown cloth in good condition (not be crushed, deformed, damaged, damp, etc.), so you can load it to the mask making machines directly after the delivery, no extra waste!
