Problems solved by technology

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

Abstract

The invention belongs to the technical field of packaging materials, particularly relates to a coating film and discloses a BOPE (biaxially-oriented polypropylene) mutt coating film, which is characterized by comprising a function layer 1, a core layer 2 and an auxiliary function layer 3. 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 includes, by mass percent, 55% of acetic ether, 10% of C9 hydrogenated petroleum resin, 18% of metallocene polyethylene, 13% of polyvinyl alcohol, 2% of sodium hydroxide, 1% of antioxidant and 1% of dispersing agent, the core layer is made of linear polyethylene, and components of the auxiliary function layer includes, by mass percent, 56% of high-density polyethylene, 40% of ethylene-propylene diene copolymer, 3% of SiO2 and 1% of antioxidant. The BOPE mutt coating film is fine in printing performance and has an extinction function.

Description

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