AI Technical Summary

Technical Problem

The printing speed of existing aluminum-plastic composite strips on rotary printing equipment cannot be increased, which cannot meet the needs of high-efficiency production.

Method used

By optimizing the structure of the aluminum-plastic strip and the composition of the film formulation, the adhesion of the printed layer is improved, the flexibility of the material is enhanced, and the contact angle between the substrate and the roller is increased. The structure consists of an inner film layer, a first adhesive layer, a barrier layer, a second adhesive layer, and an outer film layer arranged sequentially from the inside out. Polyethylene materials of different densities are used in the inner and outer film layers, and the density is increased or decreased layer by layer to enhance adhesion.

Benefits of technology

It enables high-speed printing on aluminum-plastic strips, with a maximum printing speed of 170–420 m/min, suitable for packaging of nursing products, food, pharmaceuticals and industrial adhesives.

Abstract

The application discloses an aluminum-plastic strip applied to high-speed printing, which comprises an inner film layer, a first adhesive layer, a barrier layer, a second adhesive layer and an outer film layer arranged in sequence from inside to outside, and the aluminum-plastic strip is formed through extrusion molding; the inner film layer comprises a heat-sealing layer, a first supporting layer and a first composite layer arranged in sequence from inside to outside; and the outer film layer comprises a second composite layer, a second supporting layer and a printing layer from inside to outside. Through the application, the adhesion of the printing layer is improved by starting from the formula of the printing layer of the strip and by adjusting the proportion of different polyolefin materials, so that high-speed printing is realized.
