Abstract

The invention relates to the technical field of pulp-molding packaging products, particularly to a pulp-molding packaging product and a manufacturing method thereof. The manufacturing method comprises the steps as follows: pulping, molding (pulp sucking and dewatering), demolding, hot-pressing shaping and the like; and the structural strength of a pulp-molding wet blank is enhanced, the tearing phenomenon occurring easily during demolding is eliminated, the difficulty of demolding is reduced, on one hand, the production difficulty is greatly reduced, improvement of the yield is facilitated, on the other hand, the inclination degree of the tapered structure of the manufactured product is further reduced, minimum inclination angles formed by side edges and bottom edges of the pulp-molding packaging product can be 1.5 degrees, the size of an internal empty space of the pulp-molding packaging product during packaging is greatly reduced, and the capacity for protecting a packaged product is improved. The pulp-molding packaging product is made of bagasse, waste paper and the like, has the advantages of capacity for reducing consumption of forest resources, low environmental pollution, high quality and low price and is broad in development and application prospect.

Description

technical field

[0001] The invention relates to the technical field of pulp molded packaging products, in particular to a pulp molded packaging product and a manufacturing method thereof. Background technique

[0002] Pulp molded packaging products are a new type of packaging material that is green, environmentally friendly, and energy-saving. It is mainly made of degradable bagasse and waste paper, which can reduce the consumption of forest resources. The advantages of low cost have been widely used in the packaging of electronic communications, furniture, agricultural and sideline products, toys and other industries. Pulp molding packaging products are formed by absorbing pulp with a certain concentration (generally about 0.5~3%) through the mold under negative pressure (after molding, the moisture content of the wet billet reaches 70%-75%), so that the pulp fibers are evenly distributed in the mold Surface, so as to form a wet paper mold base with the proposed geometric ...
