The disposable mask is made of two layers of 28 grams of non-woven fabric; the nose beam is made of environmentally-friendly plastic strips, does not contain any metal, and is equipped with breathable, comfortable and suitable for electronic factories, daily use.
he pore size is closely related to the fabric venting function. The larger the average pore size of the same fabric, the better the gas permeability; there are obvious differences in the pore size and air permeability of different fabrics. The double-knit fabric has a much lower air permeability than the single-knit fabric, so the double-knit fabric has a very good barrier property of harmful substances. Nonwoven fabrics generally exhibit a single fiber network structure with greater gas permeability.
Along with the rapid development of China's economy, the domestic commodity market is also becoming more prosperous, and the quality of people's days is gradually improving, so the requirements for the packaging of goods are getting higher and higher.
