Abstract

The invention relates to a high-strength, heat-resistant and anti-static masterbatch BOPP (biaxially oriented polypropylene) packaging film and belongs to the technical field of plastic film materials. The high-strength, heat-resistant and anti-static masterbatch BOPP packaging film is characterized by comprising a middle layer, an inner surface layer and an outer surface layer, wherein the middle layer is a main reinforcing layer and is made of graphene blended polypropylene masterbatch; the inner surface layer and the outer surface layer are functional layers and are made of graphene blended polypropylene masterbatch; the total thickness of the middle layer, the inner surface layer and the outer surface layer is 8-20 mu m. The three layers of raw materials of the packaging film comprise identical components and can be well combined to form an integrated cast sheet, the packaging film has the high tensile strength and the excellent anti-static effect, mounting of a static electricity remover can be avoided, the heat resistance is increased by 20-25 DEG C, and the product has the advantages of simple production technology, high production efficiency, easiness in industrial implementation and the like.

Description

technical field [0001] The invention belongs to the technical field of plastic film materials, in particular to a high-strength heat-resistant and antistatic masterbatch BOPP packaging film. Background technique [0002] At present, biaxially oriented polypropylene (BOPP) film is a very important flexible packaging material. Compared with traditional plastic packaging films, it is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength , Rigidity, toughness and good transparency, etc., so it is widely used in food, medicine and other packaging fields. [0003] However, BOPP packaging film also has many shortcomings. For example: (1) Although its existing mechanical properties are better than ordinary extrusion blown films, it is still difficult to meet special packaging requirements such as high strength and high toughness. Increasing its mechanical properties by increasing the thickness makes the production process complicated and difficul...
