Claim:
1. A method for fabricating a bubbler, comprising steps of: (a) preparing a paper material, applying an extrusion coating on a first surface of the paper material laminating a polypropylene (PP) material onto the first surface of the paper material to form a PP film; (b) subjecting a second surface of the paper material to a screen printing process, screen printing a hydrophilic polyurethane (PU) foaming material onto the second surface of the paper material to form a hydrophilic PU foaming film; (c) color printing a print material onto the hydrophilic foaming film to form a pattern layer; (d) trimming the paper material to form a paper plate having a desired range; and (e) forming the paper plate as an utensil, and enabling the hydrophilic PU foaming film to form a three dimensional pattern area on a surface of the utensil by being heated and thus foaming with a heating temperature presenting when the utensil is formed.
