Paper-plastic package box and manufacturing method thereof

Abstract

The invention provides a paper-plastic package box and a manufacturing method thereof. The manufacturing method of the paper-plastic package box comprises the following steps that a volumed thin film is unwound, and after patterns are printed, the thin film is wound; the thin film printed with the patterns and surface paper are wound after being combined; a forming procedure of corrugated paper is conducted, and a composition procedure of the composite surface paper, the corrugated paper and inner paper is conducted; a cutting-off procedure is conducted, and cutting, line folding, binding and forming procedures are conducted. According to the manufacturing method of the paper-plastic package box, technological processes are simplified, working efficiency is improved, and production cost is reduced. By heating rollers through which the corrugated paper, the compote surface paper and the inner paper pass, bonding firmness of the corrugated paper, the compote surface paper and the inner paper is enhanced. The gap between second compression roller is equal to the sum of the thickness of the composite surface paper, the thickness of the corrugated paper and the thickness of the inner paper, so that the second compression rollers have non compacting force on composite paper boards and only play a traction and composite role, and it is avoided that strength of the composite paper boards is reduced because the corrugated paper is flattened during composition.

Description

technical field [0001] The invention belongs to the technical field of packing boxes, and in particular relates to a method for manufacturing a paper-plastic packing box and a paper-plastic packing box manufactured by the method. Background technique [0002] At present, carton packaging is widely used, and most commodities are packed in cartons. In order to attract customers and promote the product at the same time, exquisite product promotion patterns are printed on the carton; for waterproof, wear-resistant and visual effects after printing, a film is applied on the outer surface of the carton to become paper-plastic packaging box. [0003] At present, the manufacturing method of paper-plastic packaging boxes is as follows: firstly, the cutting process cuts the facial paper into the required size of the paper-plastic packaging box; after that, the offset printing process uses an offset printing machine to offset the pattern on the outer surface of each facial paper; The...
