Abstract

The invention provides a composite packaging material with a surface wiredrawing effect and a preparation method of the composite packaging material. The preparation method comprises a film casting process, a hot pressing process and a dry compounding process. The film casting process comprises the step of cooling a raw material in a three-layer co-extrusion casting station to prepare a modified casting polypropylene film; the casting PP film is subjected to hot pressing on a metal wire-drawing template to achieve a metal wire-drawing effect; and finally, the casting PP film is subjected to dry compounding with an aluminized VMPET film and to secondary compounding with a PE film so as to finally prepare the composite packaging material with the metal wiredrawing effect. According to the invention, a special functional formula design is applied, and innovative application of metal wiredrawing effect on the plastic composite packaging material is realized through a special processing technology and an evaporation aluminized film technology. The prepared film material shows excellent stability, heat resistance, impact resistance, pressure resistance and excellent subsequent reprocessing stability under a normal state or a high-temperature condition.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a composite packaging material with metal wire drawing on the surface and a preparation method thereof. Background technique [0002] The packaging industry emphasizes personalization visually, pursues aesthetic effects, is language-oriented, and realizes the pursuit of beauty according to each person's different aesthetics. In order to meet the market demand, while ensuring the quality of the product, the design of the appearance packaging is strengthened to attract consumers' attention. The appearance design of packaging refers to the aesthetic feeling of the product's shape, pattern or its combination, as well as the combination of color, shape and pattern, and is suitable for industrial applications. Through various shapes, patterns and materials, it has unique Its own characteristics, but also has a strong visual impact and aesthetic design form, which fully embodies and ...
