Abstract

A polyolefin film having between about 10% and about 95%, by weight of the polyolefin film, of recycled polyolefin is described. The polyolefin film has an Average Hole Count between about 0.0 and about 10.0, according to the Gel Count Test Method. The polyolefin film has an Average Gel Count between about 0.0 and about 100.0, according to the Gel Count Test Method. The polyolefin film has an Average Relative Gel Height between about 0.0% and about 150.0%. The polyolefin film has a Total Spot Count between about 0.0 and about 100.0, according to the Gel Count Test Method.
