Abstract
The invention discloses a polypropylene film. The polypropylene film comprises a surface layer, a bottom layer, a middle layer, an electroconductive layer and a supporting layer; the middle layer, theelectroconductive layer and the supporting layer are arranged between the surface layer and the bottom layer; the middle layer, the electroconductive layer and the supporting layer are compounded; the surface layer and the bottom layer are anti-electrostatic layers; the components of the surface layer and the bottom layer comprise polypropylene and an anti-electrostatic agent; the middle layer isformed by filling a plurality of supporting cavities and polyurethane; the electroconductive layer comprises a round convex block and an electric conductor which is arranged on the round convex blockat intervals; the convex block is in run-through connection with the middle layer and the supporting layer. The polypropylene film provided by the invention is simple in structure and adopts a multi-layer composite structure, the multi-layer composite structure is arranged between the surface layer and the bottom layer, the film structure has a good supporting effect, and the electroconductive layer is arranged, therefore, the whole film has electroconductivity and prevents static electricity.
Description
technical field [0001] The invention relates to the field of textiles, in particular to a polypropylene film. Background technique [0002] BOPP film is biaxially oriented polypropylene film. The production of BOPP film is to first make the melt of high molecular polypropylene into a sheet or thick film through a narrow and long die, and then in a special stretching machine, at a certain temperature and At a set speed, it is stretched in two horizontal directions (longitudinal and transverse) simultaneously or step by step, and is made by proper cooling or heat treatment or special processing (such as corona, coating, etc.) Film, BOPP film is a very important flexible packaging material, BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency. The thin films currently used have simple structures, are not effective in use, and cannot conduct electricity. Contents of the invention [...
