Fiber-reinforced film processes and films

摘要

Cast-film process for making a fiber-reinforced film is disclosed. The process includes providing at least a first thermoplastic resin, melting the at least first thermoplastic resin, extruding the at least first thermoplastic resin through a first extension die to form a first thermoplastic film, providing at least a second thermoplastic resin, melting the at least second thermoplastic resin, extruding the at least second thermoplastic resin through a second extension die to form a second thermoplastic film, transporting the first and second thermoplastic films along respective casting rollers, and introducing a plurality of fibers between the first and second thermoplastic films so as to form a fiber-reinforced film having a thickness between about 0.2 mil to about 2.0 mils and having a first thermoplastic layer, a second thermoplastic layer, and a plurality of fibers dispersed therebetween. Cast-film process for making a fiber-reinforced bag is also disclosed.
