Abstract

The invention discloses a BOPP / PE film suitable for double-sided printing and a processing method thereof, relates to the field of film technology, adopts a three-layer co-extrusion composite method of an outer layer, a middle layer and an outer layer, and the outer layer contains polypropylene Copolymer, polyethylene copolymer and printing agent, the middle layer comprises polypropylene homopolymer, reinforcing agent and antistatic agent; The present invention adopts the three-layer co-extrusion compound mode of outer layer, middle layer, outer layer to prepare BOPP / PE film, both sides of the BOPP / PE film can be printed with graphics and text, which solves the problem that only one side of the conventional BOPP film can print graphics and text, and the BOPP / PE film has good printing performance and excellent Mechanical behavior.

Description

BOPP / PE film suitable for double-sided printing and its processing method Technical field: The present invention relates to technical field of film, be specifically related to a kind of BOPP / PE film that is applicable to double-sided printing and addition thereof. work method. Background technique: BOPP film is generally a multi-layer co-extruded film, which is formed by co-extrusion of polypropylene particles into a sheet, and then through vertical and horizontal two made by stretching in one direction. It has the characteristics of non-toxic, odorless and tasteless, and can be directly contacted with food and medicine. due to stretch Sub-orientation, so BOPP film has good physical stability, mechanical strength, air tightness, high transparency and gloss, toughness and durability. grind. Because the surface of BOPP film is non-polar, with high crystallinity and low surface free energy, its printing performance is poor, and it is not suitable for ink. poor adhe...
