The invention discloses a polypropylene heat sealing film with pseudo soldering performance. The film comprises the following three layers of structures which are sequentially contacted: a heat sealing layer, a core layer and an outer surface layer, wherein the heat sealing layer comprises 56-65% by mass of metallocene polyethylene, 27-34% by mass of a polyolefin elastomer, 2.5-4.5% by mass of a slipping agent and 1.0-2.5% by mass of anti-blocking agent mixed resin, the core layer is formed by mixing 97-99% by mass of co-polypropylene and 1-3% by mass of a slipping agent, and the outer surfacelayer is mainly prepared from co-polypropylene. The film provided by the invention has a lower heat temperature and a wider heat sealing window, can meet the requirement of high heat sealing strengthof edges of a multi-chamber bag and provide pseudo soldering performance of a middle isolation soldering seam and suitable heat sealing strength, is convenient for hand peeling, and has a smooth peeling surface and no phenomena of broken bags and scrap falling.
