The invention relates to a laser marking film. The laser marking film comprises a composite film structural layer, wherein the composite film structural layer comprises a laser marking layer; and the invention further provides components of the composite film structural layer. The laser marking film provided by one or more embodiments of the invention can be permanently marked to form a text and a pattern with high definitions and contrasts, so that a safe anti-fake function is obtained; meanwhile, an excellent light shielding property and a thermal composite molding property can be provided to satisfy thermal composite bonding and molding requirements between different materials.Besides as a good light shielding property is provided, a very good shielding and protective effect is obtained on the internal composing structure, and the safety is further improved; therefore, the laser marking film provided by the invention can be widely applied to data information pages in government confidential documents, identity cards and passports, ID cards, credit cards, insurance cards, driving licenses, various identification cards and the like, as well as other places where safe anti-fake functions are needed.
