A procedure for obtaining macro-holes (208) thermoformed in a thermoplastic film (1) that already has micro-holes (207) consisting of: - passing the thermoplastic film (1) between a first cylinder (3) with multiple needles on its surface and a second cylinder (4) with multiple grooves, - keep the thermoplastic film (1) adhered to the cylinder that carries the needles and at a temperature close to the softening point and below that of the melting point of the film (1 ), - remove the thermoplastic film (1) from the contact with the cylinder that carries the needles by means of a third cylinder (5) that is perforated on the surface, in which the multiple needles of the first cylinder (3) are coupled during rotation in the grooves of the second cylinder (4) and in the perforations of the third cylinder (5), characterized in that the third cylinder (5) will exert an adhesion force on the thermoplastic film (1) which is greater than the force of adhesion of the film (1) on the cylinder incorporating the needles, the adhesion force of the third cylinder (5) being performed on the thermoplastic film (1) using a vacuum or by means of electrostatic electricity charged with a polarity opposite to that of the third cylinder (5) and thermoplastic film (1).Un procedimiento para obtener macro-orificios (208) termoformados en una película (1) termoplástica que ya tiene micro-orificios (207) que consiste en: - hacer pasar la película (1) termoplástica entre un primer cilindro (3) con múltiples agujas en su superficie y un segundo cilindro (4) con múltiples ranuras, - mantener la película (1) termoplástica adherida al cilindro que porta las agujas y a una temperatura cercana al punto de ablandamiento e inferior a la del punto de fusión de la película (1), - retirar la película (1) termoplástica del contacto con el cilindro que porta las agujas mediante un tercer cilindro (5) que está perforado en la superficie, en el que las múltiples agujas del primer cilindro (3) se acoplan durante
