Abstract

A method for fabricating a bubbler is disclosed, which is performed by laminating a polypropylene (PP), PE, CPET film onto a paper material surface to form a PP, PE, CPET film, and then screen printing or coating a hydrophilic polyurethane (PU) material onto another surface of the paper material to form a hydrophilic PU foaming material, then color printing a print material onto the hydrophilic foaming film to form a pattern layer, trimming the paper material to form a paper plate having a desired range, and 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, whereby a three dimensional pattern area may be directly formed onto a surface of a utensil.

Claims5

Dependent claims

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.
