Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paper packaging boxes, in particular to a high temperature resistant corrugated paper packaging box. Background Art

[0002] Corrugated boxes are widely used in various packaging of industrial products because they are light, foldable, low-cost, green and environmentally friendly, easy to change specifications, can be printed with high quality, and can be used as a renewable resource after recycling. Because corrugated boxes are made of paper materials, their heat resistance is relatively low. When processing corrugated boxes, a heat-resistant coating will be applied to their surface, which can improve the high temperature resistance of the outside of the corrugated box.

[0003] A Chinese patent with announcement number "CN210455531U" discloses a high-temperature resistant corrugated cardboard box, including a bottom plate, a vertical side plate is fixedly installed on the outer side of the upper end of the bottom plate, and the vertical side plate and the bottom plate are an integral structure, a front cover plate is fixedly installed on the front of the upper end of the vertical side plate, a rear cover plate is fixedly installed on the rear of the upper end of the vertical side plate, a left cover plate is fixedly installed on the left of the upper end of the vertical side plate, and a right cover plate is fixedly installed on the right of the upper end of the vertical side plate, and the front cover plate, the rear cover plate, the left cover plate and the right cover plate are all an integral structure with the vertical side plate.

[0004] However, this corrugated cardboard box still has some shortcomings. When using the corrugated cardboard box, the items to be packaged will be placed inside the box. Because the entire corrugated cardboard box is closed in a wrapped state, the items placed in the box cannot be viewed. When the items are damaged, the user can only find out when opening the corrugated cardboard box, so that the user cannot find out in the first time, thereby reducing the security of protecting the items.
