Nano-polypropylene multilayer packaging material and production method thereof

The invention discloses a method for producing nanometer polypropylene multi-layer packaging materials and products, and relates to the technical field of preparation technology of packaging materials and products. The technical problem to be solved is to provide a new type of packaging material and a method for manufacturing the same, which has a wide range of uses, economy, safety, and environmental protection, is simple to make, and has a small investment in equipment. The technical points are: the inner and outer layers are composed of polypropylene powder and nano-scale silica, and the core layer is composed of nano-silica, titanium dioxide, zinc oxide and other raw materials and polypropylene, polyethylene synthetic resin. Between the inner layer and the outer layer, the nanometer raw material is embedded in the gap of the molecular chain of polypropylene resin to form a new material with special functions, and can be widely used for the packaging of food and beverages. The manufacture of its products is simple, easy and less investment in equipment.
