| 摘要 |
A foam container is made. A foam material is uniformly coated on at least one surface of the container. The foam material is formed by mixing a PU aqueous liquid, a defoamer, a thickener, a foaming agent, an adhesive and an additive. Fabrication speed is improved with reduced power consumption. The container thus fabricated has increased thickness, good hydrolysis resistance, good adhesion (without crumbs dropped), good heat insulation, good scratch resistance, good abrasion resistance, good printability and good workability for continuous production. |

1. A method of fabricating a foam container, comprising steps of:
(a) obtaining a container; (b) uniformly coating a foam material on at least one surface of said container, wherein said foam material is obtained by mixing a PU aqueous liquid, a defoamer, a thickener, a foaming agent, an adhesive and an additive; and (c) heating up said container coated with said foam material to obtain a foam layer on said at least one surface of said container. |
