specific Embodiment approach

[0007] 1) Through die-cutting and folding, the formed paper products are produced. For the cartons that need ventilation (such as boxes for transporting chicks), several ventilation holes are punched at the same time as die-cutting. For paper products that need to be sticky, they can be folded Paste during the process or after folding. In order to improve the overall strength, the load-bearing boards of paper products, especially cartons, should be set as vertical boards. For ready-made paper products, you can directly enter the next step;

[0008] 2) Manufacture a matching mold according to the design shape of the paper product. Corresponding to the bending part of the paper product, the edge of the mold should be at right angles, and corresponding to the plane of the plane cardboard, the mold should be plane;

[0009] 3) Use a press, such as a hydraulic press, to pressurize both sides of the cardboard of the paper product through a mold, and keep it for a certain period of ti...

Abstract

A method for strengthening paper product features that a die set whose shape is same as the shape of the paper product to be srengthened is used to press and heat the both surfaces of the paperboard of the paper product at 200-500 deg.C under 20-40 Kg / sq.cm for 5-60 s.

Description

technical field [0001] The invention relates to a method for strengthening paper products. Background technique [0002] After various paper products such as cartons and paper jigsaw puzzles are made, there is no feasible way to increase their strength. Therefore, there are generally defects of low strength, which affects the use effect and limits the use range. In order to improve the strength, practice It is often necessary to use other materials or compound multiple materials, which not only increases the cost, wastes resources, but also causes environmental pollution due to the use of other materials. Contents of the invention [0003] In order to overcome the defect of low strength of existing paper products, the utility model provides a method for strengthening paper products. This method adopts physical means to strengthen paper products, and can obviously improve the strength of paper products at a small cost. Strength, and will not cause waste of resources and en...
