The bridge of the nose is the "backbone" of the mask. It is mainly used as a rigid strip inside the mask to support the fit of the mask and the nose frame, so that bacteria cannot easily enter the respiratory tract. The nose bridge strip is also known as the full plastic nose strip, the nose bridge bar, the nose bridge line and the ribbed nose bridge strip. The nose bridge strips are all made of polyolefin resin, which can be melted similarly to non-woven materials.
The structure of the bridge of the nose needs to have the excellent performance of bending and deforming with the action of external force, not rebounding after losing the action of external force, and keeping the existing shape unchanged, so as to prevent the glasses from forming moisture, and should have better comfort. The role of masks in the use of masks is mainly to fit and shape according to the face shape of different people.
The all-plastic nose bridge has the advantages of the existing nose bridge, and it also has the excellent performance of bending and deforming with the action of external force, not rebounding when the external force is lost, and keeping the existing shape unchanged. Non-woven materials are similarly fused. After use, it is recycled into non-hazardous plastic products, which improves the efficiency of recycling and makes beneficial contributions to environmental protection.
Due to the increased awareness of environmental protection, the market, especially the foreign market, has a very strong demand for environmentally friendly nose bridge strips that are less polluting and easy to recycle.
The all-plastic nose bridge can be modified and produced by using polymer materials as the base material. It is halogen-free, o-benzene-free, and plasticizer-free. It meets environmental protection requirements such as Rosh and REACH. It is specially used for masks (especially disposable medical masks, Medical surgical masks, N95 and other high-level requirements) Nose wire or other polymer composite materials that need to be produced by stereotyped product accessories.
