[0002] Most of the pulp molded products at home and abroad are produced by the traditional suction filtration process with single-layer pulp and one-time molding. They mostly use pulp board, plant fiber, waste paperboard and their mixture as raw materials. After pulping, the mold is immersed in the pulp pool and vacuum suction is formed into a wet blank. After hot pressing and drying, a single-layer pulp molded product with only one kind of pulp fiber is made. In order to improve the pulp molded products, people have designed a double-layer grouting process.
