3-Ply Surgical Masks 50pcs

Visual Test

If you cut open your mask, you should see a very obvious 3-layers. The 3 layers would typically consist of an outer hydrophobic non-woven layer (translucent), middle melt-blown layer (white), and an inner soft absorbent non-woven layer (green, blue, or white).

Non-flammability Test

The middle layer of a surgical mask is a melt-blown fabric, not made with paper, therefore, if you light it with a flame, it will not burn like paper. Instead, it melts without flame.

Water-resistant Test

The outer-most layer is designed to be waterproof. Pour some water onto the outer layer and you should be able to see that the mask repels water properly.

Electrostatic Adsorption Test

There is an electrostatic effect in the melt-blown layer. If you tear the melt-blown layer into strips, you will feel the electrostatic adsorption effect, and you can also adsorb the melt-blown layer on stainless steel due to its large amount of electric charge.
