Nanometer winding film -- the full name is nanometer scale layer extruded winding film, 55 layers of nanometer scale winding film is a kind of nanometer scale 55 layers film co-extrusion technology, a variety of materials (PP, PEO, etc.) summer combination extrusion molding, the formation of a single layer thickness in nanometer level, the number of layers is 55 layers of high strength, high toughness winding film.
The number of layers is higher than that of ordinary co-extruded film technology, generally in 2-17 layers;
The higher the number of layers, the better the physical and mechanical properties of the film material, which is mainly manifested in the geometric increase of elongation and the ability to withstand higher load force and puncture strength;
Ordinary film because of the production process, it is difficult to achieve complete thickness uniformity, even in the extrusion process discontinuous situation. And manufacturing costs are high. In addition, there will be a higher oxygen intake between the materials (meaning that small bubbles may appear that are not visible to the naked eye);
At present, the advanced nanofilm technology is 55 layers, the overall thickness is 12-20 microns, the overall thickness is lower than the ordinary film.
