Abstract: A micro-perforated laminae includes a layer of material having a plurality of spaced-apart perforations, in which the total open orifice area of the perforations is about 0.1% to 17.0% of the total surface area of the layer of material. The layer of material can be a thermoplastic material, metal foil, cellulosic film, paper and/or nonwoven. The perforations can be slits, with each slit having a length of no more than about 100 mils (2.54 mm). Alternatively, the perforations can be holes, in which each hole has a diameter of no more than about five mils (0.13 mm). The total open orifice area of perforations can be in the range of about 0.1 mm2 to about 17 mm2 per square centimeter of the total surface area of the micro-perforated laminae.

Abstract: A process of forming a perforated packaging film with simultaneous liquid retention and gas/vapor venting characteristics, including the steps of forming a polyolefin film, perforating the film with perforations being either slits having a length of no more than 100 mils or holes having a diameter of no more than about 5 mils, and spacing the perforations from each other so that the total open orifice area is no greater than 20 mils/in2.

Abstract: A process for producing artificial fibers without significant fiber surface hydrolysis from waste cellulose acetate continuous filament or filter rods which can then be used in the manufacture of specific paper products. Waste cellulose acetate fibers generated during filament manufacture or cigarette manufacture as off quality production is used for rendering the into a form suitable for specific paper manufacture. Paper products which comprise 1-10% of the subject fiber as part of the pulp furnish is also disclosed.
