Abstract
A foamable structure includes a film shell having a bottom face and a peripheral wall, and a foamable material mounted in the film shell and having a bottom face combined with the bottom face of the film shell, and a peripheral wall combined with the peripheral wall of the film shell. Thus, the film shell is coated on the periphery of the foamable material, so that the film shell is combined with the foamable material rigidly and stably, thereby preventing the foamable material from detaching from the film shell due to a pulling action of an external force.
