Abstract
A method for manufacturing a right-angled pulp product uses a mixture of cellulose fibers as pulp. Steps in the method include taking the pulp to form a flat shape, pressing and heat-drying the flat-shaped pulp to form a pulp product having a plurality of troughs, taking out the pulp product, cutting off a burr around the pulp product, applying adhesive onto each of the troughs, and bending two adjacent plates at two sides of each trough to form a right angle and a fixed shape.
