The invention discloses a multilayer composite food packaging film. The multilayer composite food packaging film comprises a packaging film and a polyvinyl chloride layer, the polyvinyl chloride layeris fixedly arranged on the surface of the packaging film, the bottom of the polyvinyl chloride layer is fixedly connected with a polyhydroxyalkanoate layer, the bottom of the polyhydroxyalkanoate layer is fixedly connected with a polyethylene layer, the bottom of the polyethylene layer is fixedly connected with a polycarbonate layer, and the bottom of the polycarbonate layer is fixedly connectedwith a biaxially oriented polypropylene film. The polyvinyl chloride layer can increase the stability of the packaging film in the daily use process; the packaging film can be combined with a printinglayer to make the surface of the packaging film beautiful; and the polyhydroxyalkanoate layer has biodegradability, and also has hot workability of plastics, so the finally obtained film has a very high water vapor permeability, thereby the multilayer composite food packaging film can be applied to long-time fresh product fresh-keeping packaging, is an ideal packaging material, and is suitable for being widely promoted and used.
Description
technical field [0001] The invention relates to a packaging film, in particular to a multilayer composite food packaging film. Background technique [0002] In recent years, fast food and beverages at home and abroad have developed very rapidly, but traditional food packaging materials cannot be used as food. Food packaging film is an important part of food packaging. Ordinary food packaging film will use paper base or aluminum base or PE and other materials. Due to the aesthetic needs of food packaging, people have higher and higher demands on the beauty and practicality of food packaging films. [0003] However, in daily use, packaging films are used in a wide range of applications. All kinds of food need to be packaged through packaging films. Some need to be stored for a long time, some need high temperature resistance, and some need high structural strength. To this end, we propose a multilayer composite food packaging film.
