A vapor-deposited foamed body having a film 15 vapor-deposited on the surface of a foamed plastic formed body containing foamed cells 1 therein, wherein in the surface X of the foamed plastic formed body 10 serving as the under-layer on where the film 15 is to be vapor-deposited, the porosity of the foamed cells 1 is suppressed to be not more than 30% in the surface layer portion 10a to a depth of 50 µ m from said surface. The vapor-deposited foamed body is obtained by vapor-depositing the film on the surface of the foamed plastic formed body such as a foamed container, the vapor-deposited film being uniformly formed and being effectively prevented from peeling off.

B32B 9/00 - Layered products essentially comprising a particular substance not covered by groups
B65D 1/00 - Rigid or semi-rigid containers having bodies formed in one piece, e.g. by casting metallic material, by moulding plastics, by blowing vitreous material, by throwing ceramic material, by moulding pulped fibrous material or by deep-drawing operations p
B65D 1/02 - Bottles or similar containers with necks or like restricted apertures, designed for pouring contents
C23C 16/50 - Chemical coating by decomposition of gaseous compounds, without leaving reaction products of surface material in the coating, i.e. chemical vapour deposition (CVD) processes characterised by the method of coating using electric discharges
