Embodiment approach 1

[0018] Embodiment 1: The manufacturing method of the lightweight plastic packaging box of the present invention, wherein,

[0019] 1. Create a groove on the light board and heat it with a hot gas torch, apply hot melt adhesive in the groove, bend and fix it for one hour, and make the main body of the packaging box with double-sided openings;

[0020] 2. Preheat around the bottom cover of the box, apply hot melt adhesive and continue heating. After about 10 minutes, quickly compound it to an opening of the main body of the packaging box, and seal the opening. The bottom cover of the box is made integrally with the main body of the packaging box. become;

[0021] 3. After the hot melt adhesive has cooled to normal temperature, apply hot melt adhesive evenly on each gap inside the main body of the packaging box to ensure the sealing performance of its structure;

[0022] 4. Stainless steel edge sealing is fixedly installed on each ridge line outside the main body of the packing...

Abstract

The invention discloses a manufacturing method for light plastic packing boxes. The method includes: firstly, utilizing a light board to make a packing box body with two sides open; secondly, preheating the periphery of a bottom cover of the box body, coating the bottom cover with hot melt adhesive prior to continuous heating, and then rapidly combining the bottom cover on one opening of the packing box body to seal the opening; thirdly, after the hot melt adhesive is cooled to normal temperature, coating gap positions inside the packing box body with the hot melt adhesive; fourthly, fixedly mounting stainless steel seal edges on all ridges outside the packing box body, and hinging an end cover at the other opening, wherein the end cover is in seal fit with the packing box body when closed. The light board is composed of a middle core layer of a hexagonal honeycomb structure and surface layers, the surface layers are arranged on two side faces of the middle core layer, the middle core layer is composited by polypropylene and glass fibers and is of the hexagonal honeycomb structure by injection molding, the surface layers are made of polypropylene resin infiltration glass fiber cloth via hot pressing compositing, and the surface layer, the middle core layer and the surface layer are laid between two pressing boards to composite the light board.

Description

technical field [0001] The invention relates to a manufacturing method of a lightweight plastic packing box.
