Wire clamping production method for improving tearing strength of carton

Abstract

The invention discloses a wire clamping production method for improving the tearing strength of a carton. The method comprises the following steps: carrying out pre-gluing treatment on 20/3 strands ofpolyester threads; adding the treated polyester thread with an adhesive into a specified position in a paperboard from a double-faced machine of a paperboard production line before the paperboard isbonded; carrying out gluing and pressing treatment on the paperboard, so that the upper paperboard, the lower paperboard and the polyester threads with the glue are pressed into a whole; drying the paperboard obtained after compression molding; and after drying, cutting the compressed and molded paperboard. According to the method, 20/3 strands of polyester threads are adopted, due to the specificity of the wire clamping material, the problem that normal driving is affected due to the fact that transverse cutter cutting cannot be conducted is solved, and the problem that due to the fact that the polyester wires are subjected to pre-gluing treatment, swelling is caused due to the fact that the clamping wires and the paperboard are not fully bonded is solved.

Description

technical field [0001] The invention relates to the technical field of carton production and processing, in particular to a thread clamping production method for improving the tear resistance of cartons. Background technique [0002] The internal clamping process of the carton can improve the tear strength of the carton. At present, some customers, especially the manufacturers of poultry and seafood, need to adopt the carton clamping process, which has solved the problem of carton tearing and breaking during the process of packing, transportation and loading and unloading. [0003] The carton clamping process is to add special 8 lines from the double-sided machine of the cardboard production line to the specified position inside the cardboard before the cardboard is glued. Due to the selection of the line, there will be the actual problem that the cross-cutting will continue to affect the normal driving and the clamping position The problem of poor adhesion such as bulging ...

[0003] The carton clamping process is to add special 8 lines from the double-sided machine of the cardboard production line to the specified position inside the cardboard before the cardboard is glued. Due to the selection of the line, there will be the actual problem that the cross-cutting will continue to affect the normal driving and the clamping position The problem of poor adhesion such as bulges can not guarantee the quality of the carton. The reason for the bulge and poor adhesion at the clamping line is that the clamping line is not fully coated with glue
