Lian Pack丨How is The Dry Press Production Process for Moulded Pulp Containers

In the process of pulp molding production, the dry way of wet paper blank is heating and drying directly in the mold. That is to say, in the cold pressing stage, after the semi-wet paper blank is extruded and dehydrated, the product is hot pressed and dried directly in the pressure mould. When DRYING, THE drying process conditions (such as die pressure, heating time, temperature, etc.) should be adjusted according to the conditions of the paper mold products to ensure the quality of the paper mold products after drying. The density, stiffness and strength of the paper molded products dried in this way are dryness, which is superior to the drying method, and some dried products no longer need shaping and trimming.
