Laminating method: Coat a layer of protective film on the surface of the paper to improve the water resistance and oil resistance of the paper bowl.

Heat Pressing: Pressing the paper into a bowl shape using heat and pressure to increase its strength and stability.

Injection molding: Heated plastic particles are injected into a mold, cooled and hardened to form the shape of a paper bowl, and the inner layer of the paper is usually coated with a film to prevent leakage.
