Claims13
A method for reclaiming polymeric film from mixed plastic waste comprising polymeric film and cellulosic fiber, said method comprising the steps of:
- Introducing the plastic waste into apparatus adapted to reduce the polymeric film to pieces having a maximum dimension ranging between about 1 inch and about 4 inches;
- Separating the polymeric film from a portion of the cellulosic fiber by passing the plastic waste through at least one wash tank;
- Further reducing the size of the pieces of polymeric film to pieces having a maximum dimension of about 1/2 inch;
- Separating the polymeric film and a further portion of the cellulosic fiber by flotation with agitation;
- Dewatering the polymeric film;
- Drying the polymeric film to a moisture content of less than about 10 weight percent;
- and
- Rolling the polymeric film into pellets.
