Barrier film for paper-containing microwavable packaging material

The invention relates to the field of packaging materials, and discloses a barrier film for a paper-containing microwavable packaging material. The barrier film comprises a barrier substrate layer, a first inorganic layer is arranged on the surface of one side of the barrier substrate layer, a protective layer is not arranged on the side, away from the barrier substrate layer, of the first inorganic layer, and the side, away from the annular packaging precursor, in contact with the liquid product is arranged on the first inorganic layer; a second anchoring coating is arranged on the surface of the other side, opposite to the first inorganic layer, of the barrier substrate layer, and the second anchoring coating is used for being bonded with a second bonding layer close to one side of the inner sealing layer of the packaging material. By utilizing the barrier film, the problems of many processing steps and high cost of the existing microwave barrier film can be solved. 本申请涉及包装材料领域，公开一种用于含纸质可微波包装材料的阻隔膜。该阻隔膜包括阻隔
