A method of making multiwall plastic bags wherein half-width foil webs are unwound from respective rolls below a segment of a path within which a multilayer full-width web is guided. The half-width webs can be slit and unfolded or simply unfolded to form full-width single-layer webs which are combined by superimposition to form the multilayer full-width web. The latter is folded and the folded multilayer width is formed into the bags.
