Abstract

The invention discloses a matte BOPP aluminum laminated film for labels. The matte BOPP aluminum laminated film comprises a matte BOPP base film and an aluminum layer plated on the upper surface of the matte BOPP base film, wherein the matte BOPP base film comprises a corona layer, a middle layer and a heat-seal layer in turn from top to bottom. A production technology for the matte BOPP aluminumlaminated film for labels comprises the following steps: 1) firstly, adopting an extruder for extruding the matte BOPP base film; 2) preparing the matte BOPP base film in the manner of two-way stretching; 3) lastly, performing vacuum aluminizing on the upper surface of the matte BOPP aluminum laminated film at vacuum degree of above 10-4mbar. In the process of extrusion molding, a matte master batch is used and HDPE and nano-silica anti-blocking agent are added for directly molding a film with a matte effect, and no matte layer is coated, so that the coating process is avoided, the cost is saved and the influence of solvent coating on environment is reduced.

Description

technical field [0001] The invention relates to the technical field of film manufacturing, more specifically, it relates to a matte BOPP aluminized film for labels and a production process thereof. Background technique [0002] Since the application of aluminized film, optical properties such as surface gloss and transparency have been an important aspect of its performance, especially in the most widely used packaging field, high surface gloss and high transparency have always attracted attention. However, with the change of people's aesthetics, there are also diversified requirements for packaging materials, and high haze on the surface has become popular. Therefore, the development of matte aluminized film has become a new profit growth point and investment point for enterprises. [0003] At present, the matte effect is mainly achieved by coating on the market, but the matte film obtained by this method has instability in the matte effect time, and after a long time, the ...
