Abstract
A composite thermoformed tableware and preparation method thereof. The preparation method involves a preheating step, a compositing step and a thermoforming step in sequence; the preheating step heats multilayer forming materials at a temperature of 35° C. to 150° C., the forming materials have one or at least two of paper, plastic and inorganic layer; the compositing step involves stacking the preheated forming materials to form a composite material; the thermoforming step involves heat-pressing the composite material at a temperature of 80° C. to 150° C. and a pressure of 0.05 MPa to 0.5 MPa to form a three-dimensional body. The tableware is thermoformed by multiple layers of the same material or different materials, so that the thickness and strength of the tableware are higher.
