  • Patent number: 3980611
    Abstract: A thermoplastic film having dispersed therein an inert material consisting essentially of:1. coarse particles having a size greater than 2.5 microns in a concentration determined by the formulaC.sub.1 = K.sub.coarse/T 0.6where C.sub.1 is the concentration of coarse particles in parts per million, K.sub.coarse is at least equal to an emperically determined value of K.sub.coarse at the minimum concentration of coarse particles which permits escape of air during film wind-up, and T is film thickness in mils,2. medium particles having a size of 1 to 2.5 microns in a concentration determined by the formulaC.sub.2 = K.sub.medium/T 0.6where C.sub.2 is the concentration of medium particles in parts per million, K.sub.medium is no greater than an emperically determined value of K.sub.medium at the concentration of medium particles in a film having a clarity of 50%, and T is film thickness in mils, and3. fine particles having a size less than 1 micron in a concentration determined by the formula:C.sub.3 = K.sub.
