Production process of paper pulp molding product undercut

The invention relates to a production process of a paper pulp molding product undercut. According to the production process, the processing sequence of paper pulp wet blank forming, hot-pressing processing and undercut manufacturing is sequentially carried out, and is used cooperatively with the production process provided by the invention, so that a paper pulp molding product can be produced, andalso the paper pulp molding product produced by the production process provided by the invention realizes a structure with the undercut. Paper molding is employed to replace plastic absorption to make packaging paper support, and environment-friendly paper pulp is employed to replace plastic, the paper pulp can be recycled, and the use is more convenient. Besides, the whole production process ofthe paper pulp molding product manufactured by the production process provided by the invention does not need a hot melting process like a blister packaging process, simplification of the manufacturing process is realized, als
