Problems solved by technology

However, in the label industry (BOPP coating film is the upper film for making label materials), since the surface of BOPP coating film is non-polar, and the surface tension itself is not high (generally no more than 32 dyne) and falls very fast, making UV The adhesion of ink on the surface of BOPP is extremely difficult
The existing BOPP coating film has the following disadvantages: the corona value can only reach 38 dynes in one month, and the printing performance is poor

Abstract

The invention belongs to the technical field of packaging materials, and particularly relates to a BOPP (biaxially-oriented polypropylene) coating printing reinforcement film, which is characterized by comprising a function layer, a core layer and an auxiliary function layer. The core layer is positioned between the function layer and the auxiliary function layer, the function layer, the core layer and the auxiliary function layer are integrated by means of biaxially stretching after being in coextrusion, the mass percent of the function layer ranges from 1% to 8%, the mass percent of the core layer ranges from 91% to 98%, the mass percent of the auxiliary function layer ranges from 1% to 5%, raw materials of the function layer include, by mass, 55% of acetic ether, 10% of C9 hydrogenated petroleum resin, 18% of polypropylene, 13% of polyvinyl alcohol, 2% of sodium hydroxide, 1% of antioxidant and 1% of dispersing agent, raw materials of the core layer include, by mass, from 73 to 82% of polypropylene, from 10 to 15% of stiffening agent and from 8 to 12% of antistatic smooth agent, and materials of the auxiliary function layer include, by mass, 5% of SiO2 and 95% of co-polypropylene. The BOPP coating printing reinforcement film has the advantage of fine printing performance.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a BOPP coating film. Background technique [0002] Some characteristics of BOPP coating film itself make it widely used in flexible packaging industry, such as cigarette labels, laser, food packaging and so on. However, in the label industry (BOPP coating film is the upper film for making label materials), since the surface of BOPP coating film is non-polar, and the surface tension itself is not high (generally no more than 32 dyne) and falls very fast, making UV The adhesion of ink on the surface of BOPP is extremely difficult. The existing BOPP coating film has the following disadvantages: the corona value can only reach 38 dynes in one month, and the printing performance is poor. Contents of the invention [0003] The purpose of the present invention is to provide a BOPP coated printing enhancement film with good printing performance. [0004] In o...
