Problems solved by technology

At present, paper packaging materials are widely used in food, medicine and other industries. However, due to the structural characteristics of paper itself, compared with plastic foam materials, there are inherent deficiencies in heat insulation and cushioning performance, and simply rely on increased The number of layers, the thickness or the method of increasing the bulkiness of single-layer paper to a limited extent to improve the heat insulation performance and cushioning performance of paper products, the effect is not obvious; and the existing foaming materials are often rough in printing, which cannot meet the requirements. Enterprise or individual demand for excellent printing effect

Abstract

The invention provides a composite foamed paper product and its preparation method and application. The composite foamed paper product is mainly composed of a foam layer and a paper layer, wherein the material of the foam layer is 93-99% (w / w ) composite resin composed of polyolefin resin and 1-7% (w / w) foaming agent, the foaming layer is compounded and fixed with the paper layer through an extrusion coating process; the preparation method is according to 20-450 g / square Rice paper as the base material, 20-40 g / m2 composite resin as the foam layer, through the multi-layer composite cast extrusion production line at a melt temperature of 240-320 ° C, resin melt pressure 4-11KG, speed 50 - Under the processing condition of 120 m / min, composite resin and paper are compounded and processed; this paper product overcomes the problems of poor heat insulation and cushioning performance of paper and rough foaming and printing in the existing process, and can be used in food and industrial products Widely used in packaging and publishing printing fields.

Description

technical field [0001] The invention relates to a paper packaging material and its preparation method and application, in particular to a composite foamed paper product and its preparation method and application. Background technique [0002] With the continuous improvement of people's living standards, higher requirements are put forward for all kinds of packaging materials, especially those closely related to daily life, especially for packaging materials' heat insulation performance, cushioning performance and printing effect. At present, paper packaging materials are widely used in food, medicine and other industries. However, due to the structural characteristics of paper itself, compared with plastic foam materials, there are inherent deficiencies in heat insulation and cushioning performance, and simply rely on increased The number of layers, the thickness or the method of improving the bulkiness of single-layer paper to a limited extent to improve the heat insulation...
