We study generalized minimizers in the soap film capillarity model introduced in arXiv:1807.05200 and arXiv:1907.00551. Collapsed regions of generalized minimizers are shown to be smooth outside of dimensionally small singular sets, which are thus empty in physical dimensions. Since generalized minimizers converge to Plateau's type surfaces in the vanishing volume limit, the fact that collapsed regions cannot exhibit Y-points and T-points (which are possibly present in the limit Plateau's surfaces) gives the first strong indication that singularities of the limit Plateau's surfaces should always be ``wetted'' by the bulky regions of the approximating generalized minimizers.
