Is it better to pack disposable masks independently or in bulk?
Disposable masks are packaged independently, and bulk masks are not easy to keep. Disposable masks are made of more than three layers of 28 grams of non-woven fabric; the bridge of the nose is made of environment-friendly plastic strips, free of metal, breathable and comfortable, especially suitable for electronic factories and daily life. Disposable masks (medical surgical masks) can prevent respiratory tract infection to a certain extent and cannot prevent haze.
When buying, you should choose a mask with the word “medical surgical mask” clearly marked on the outer package. The disposable mask is made with an environmentally friendly full plastic nose bridge clip design, which can be adjusted most comfortably according to different face shapes. Choose internal ultrasonic spot welding, the earbands can be very firm and not easy to fall off.

Conditions of use
There are a variety of disposable dust masks, which must be selected according to different working needs and working conditions. First of all, it should be selected according to the concentration and toxicity of dust. According to GB/T18664 ‘s “selection, use and maintenance of Respiratory Protective equipment”, as half masks, all dust masks are suitable for environments where the concentration of hazardous substances does not exceed 10 times the occupational exposure limit.
Otherwise, a respirator with a full cover or a higher level of protection should be used. If particles are highly toxic, carcinogenic and radioactive, the filter material with the highest filtration efficiency should be selected. If the particles are needle-like fibers, such as slag, asbestos, fiberglass, etc., because the dust mask can not be washed, the mask with tiny fibers is easy to cause facial irritation in the facial seal and is not suitable for use.

How to quickly bag disposable masks?
How can I install the disposable mask? it’s all mechanically automated bagging. There’s no good way for you to do it manually. You’ll have to keep the status quo soon.
How many boxes of domestic three-layer disposable non-woven masks
If it is a three-layer plane non-woven mask, it is usually 50 pieces in a box of 1000 or 2000 in a box. If it is a three-layer three-dimensional mask, there are 20-60 masks in each box.
Instructions for medical protective masks
The medical protective mask is composed of a mask face and a tension band, in which the mask face is divided into three layers: the inner layer is ordinary sanitary gauze or non-woven, the middle layer is the ultra-fine polypropylene fiber melt-blown material layer, and the outer layer is the non-woven or ultra-thin polypropylene melt-blown material layer. The high-efficiency medical protective mask has strong hydrophobicity and permeability, and has remarkable filtering effect on micro-virus aerosol or harmful dust, the overall filtering effect is good, the material used is non-toxic and harmless, and it is comfortable to wear.
Medical protective masks are the best products to prevent respiratory infectious diseases, and everyone should carry them with them.
