A production process of undercut of pulp molded product

Abstract

The production process of the undercut of a pulp molded product of the present invention, which is used in conjunction with the production process of the present invention, makes it not only Pulp molded products can be produced, which also enables the pulp molded products produced by the production process of the present invention to have an inverted structure; it uses paper plastics instead of blisters to make packaging paper holders and uses environmentally friendly pulp instead The use of plastic and paper pulp can be recycled, and its use is more convenient. In addition, the pulp molded product produced by the production process of the present invention does not need a hot-melt process in the entire production process like the process of blister packaging. It not only realizes the simplification of the production process, but also avoids the pollution of the environment, and the use of paper pulp is relatively low in cost compared with plastic, so that the realization can effectively reduce the production cost.

Description

technical field [0001] The invention relates to a production process of an undercut of a pulp molded product. Background technique [0002] For a long time, the blister tray of the packaging box has been hot-melted to make an undercut to hold the item. The undercut can make the item not easy to shake in the blister tray of the packaging box and come out of the box. The article can be more firmly stuck in the blister holder of the packaging box, but because the blister holder of the packaging box is elastic, it is easy to withdraw the mold after punching, but the paper-plastic holder of the packaging box is difficult to withdraw from the mold, making the packaging paper It is difficult to make an inverted structure on the plastic tray, that is, it is difficult to make an inverted button on the paper-plastic tray of the packaging box, and finally the packaging carton has not been able to produce an inverted structure to hold the goods.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a production process for pulp molded products with undercuts. Using the processing sequence and processing technology of this production process, pulp molded products with underturned structures can be produced, so as to break the tradition that only suction Blister packaging boxes with an inverted structure can only be produced with plastic materials, and paper plastics cannot be made with an inverted structure because it is difficult to remove the mold, and the use of paper plastics can be recycled, and its use cost is low. Compared with the production process of the current blister packaging box, it does not require hot-melt processing, so that it can simplify the processing process and avoid polluting the environment, and the production is more convenient and fast.
