The pulp product is formed on a foraminous mold and, together with the mold, is heated to the softening temperature of a liquid impervious thermoplastic sheet material which is caused to be cut to size by engagement with a cutting edge on the mold whereafter the severed portion is drawn by suction and bonded to a selected surface area of the pulp product.
