The present invention mainly refers to a method for producing biofilms from cereal grains, which comprises the following steps: a) decorticating grains, b) milling the decorticated grains, c) solubilizing proteins and starches, d) adding plasticizers, e) mould pouring and f) evaporating solvents; the method optionally includes a stage for adding at least an organic or inorganic additive, which provides to the resulting product an additional characteristic such as colour, odour, texture and/or preservation. The invention further refers to a biofilm resulting from the aforesaid method and characterised in that the physical properties thereof, such as elongation, tension and thermoseal, are characteristics required for the manufacture of containers. The invention also refers to said biofilms for manufacturing containers in different forms such as bags, pads, absorbing and desorbing towels, amongst other type of containers which may be formed with biopolymeric films intended to contain an d/or preserve food.
