Perforated laminated product and method for producing this product

A method for manufacturing a laminated product formed by an extruded film of plastic material provided with protuberances that extend from one face thereof with microholes having an average diameter between 0.100 mm and 0.300 mm produced on vertices of said protuberances, and by a layer of nonwoven fabric, the method comprising:

• laminating and simultaneous through perforating, in a calendar provided with a first rotating cylinder with a smooth surface and a second rotating cylinder provided with cusps on a second rotating cylinder surface, of said film of plastic material arranged with the protuberances facing said second rotating cylinder, and of said layer of nonwoven fabric facing said first rotating cylinder, said laminating taking place with a peripheral speed of said second rotating cylinder greater than a peripheral speed of said first rotating cylinder, or said laminating taking place with said peripheral speed of said first rotating cylinder being greater than said peripheral speed of said second rotating cylinder, so that slippage between the smooth surface of said first rotating cylinder and said second rotating cylinder surface causes said perforating to produce through holes with an average diameter between 0.350 mm and 0.700 mm.
