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, and the printing performance is poor

Abstract

The invention belongs to the technical field of packing materials, and particularly relates to a coating film. A biaxially oriented polyethylene (BOPE) coating print film is characterized by comprising a functional layer, a core layer and a secondary functional layer; the core layer is positioned between the functional layer and the secondary functional layer; the functional layer, the core layer, and the secondary functional layer are subjected to coextrusion and then biaxial tension to be integrated; the BOPE coating print film comprises the following layers in percentage by mass: 1 to 8 percent of functional layer, 91 to 98 percent of core layer and 1 to 5 percent of secondary functional layer; the functional layer is prepared from the following raw materials in percentage by mass: 55 percent of acetic ether, 10 percent of C9 hydrogenated petroleum resin, 18 percent of metallocene polyethylene, 13 percent of polyvinyl alcohol, 2 percent of sodium hydroxide, 1 percent of antioxidant, and 1 percent of dispersing agent; the core layer is prepared from the following raw materials in percentage by mass: 73 to 82 percent of polyethylene, 10 to 15 percent of stiffening agent, and 8 to 12 percent of antistatic slipping agent; and the secondary functional layer is prepared from the following raw materials in percentage by mass: 5 percent of SiO2, and 95 percent of co-polypropylene. The BOPE coating print film has the characteristic of printing performance.

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, and the printing performance is poor. Contents of the invention [0003] The purpose of the present invention is to provide a BOPE coated printing film with good printing performance. [0004] In order to achi...
