ABSTRACT:
The present invention solves the problems left unaddressed by the prior known processes by providing a method to produce foamed-thermoplastic films of sufficient strength for use in consumer trash-bag applications utilizing high strength thermoplastic resins. Most broadly, the present invention comprises a blown-film bag formed from a material comprising a matrix of foamed polyolefin-based film and gaseous cells formed from a foaming agent.
