The invention discloses a PP/PE co-extrusion high barrier film and a preparing method thereof. The PP/PE co-extrusion high barrier film is composed of a three-layer structure of a printing layer, a barrier layer and a heat sealing layer. The PP/PE co-extrusion high barrier film has the high rigidity and the high heat resistance of polypropylene, can meet the requirements of high-speed automatic filling and packaging and cooking and heating, has the low-temperature heat sealing performance of polyethylene, and can meet the low-temperature storage and transportation requirement; three-layer co-extrusion curtain coating forming is adopted, a production technology is simple, the production cost is low, hygiene and environment-friendly hidden danger such as solvent evaporation and residues is avoided, a bag opening is easy to open after the film is used for making a bag, the PP/PE co-extrusion high barrier film can be independent after filling and packaging, and a user conveniently uses thefilm.
