A container of the present invention includes a paper-made container body, a waterproofing layer and a foaming layer. The container body has an outer surface and an inner surface. The waterproofing layer is coated on the inner surface in the manner of casting. The waterproofing layer mainly consists of talcum powder, resin and calcium carbonate. The foaming layer is disposed on at least a part of the outer surface. The foaming layer consists of a hinder and a thermo-expandable powder. The binder is selected from a group consisting of polyvinyl acetate resin, ethylene vinyl acetate resin, polyacrylic acid resin and a mixture thereof. The thermo-expandable powder consists of a plurality of thermo-expandable microcapsules, each of which consists of a thermoplastic polymer shell and a low-boiling-point solvent wrapped by the thermoplastic polymer shell. |
