Abstract

The invention discloses a BOPP film for shallow reticulated printing, wherein the film of three-layer construction formed by co-extrusion and bidirectional tension of the bidirectional tension level acrylic resin. The shallow reticulated printing layer comprises anti-adhesion agent 2-4% wt; and the anti-adhesion layer comprises anti-adhesion agent 3-5% wt; the core layer comprises anti-static agent 0.8-1.0% wt. The anti-adhesion agent is synthetic silica and the grain size of the synthetic silica in the shallow reticulated printing has two kinds, respectively 1-2 Mum and 2-4Mum, and the ratio of 1-2 Mum to 2-4 Mum is 0.5-1.5:3.5-4.5; and the grain size of the synthetic silica in the anti-adhesion layer is 3-5 Mum. The BOPP film is used for shallow reticulated printing with good pattern hierarchicy sense, accurate overprint, no generation of lumen 'botting', strong ink adhesion force, good antistatic effect.

Description

technical field [0001] The invention relates to a film, in particular to a biaxially stretched polypropylene film with shallow screen printing performance and used for color printing, BOPP film for short. Background technique [0002] Biaxially oriented polypropylene film has good printability, excellent impact resistance, low moisture permeability, high chemical resistance, strong thermal stability, and excellent optical properties. It is widely used in food flexible packaging, color printing, clothing and other industries. Wide range of packaging materials. The existing biaxially oriented polypropylene film used for color printing often has the phenomenon of "blocking" of the cells during shallow screen layer printing, printing lost dots, poor ink adhesion and antistatic performance, and affects the color printing effect. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned prior art, the present invention provides a BOPP film with shallo...
