ABSTRACT:
A method of making a factory end for a bag assembly, in which a removable plastic bag will be contained within a protective outer bag, includes steps of providing a tube assembly having a plastic inner tube within an outer tube; sealing one end of the plastic inner tube so as to be closed at said one end; and closing the outer tube about the closed one end of the inner tube in such a manner that no plastic material from said inner tube is permanently affixed to the outer tube, whereby the outer tube may be efficiently recycled or incinerated after it is separated from the inner tube by a consumer. The bag assembly itself is disclosed as a separate aspect of the invention. Methods for making the tube assemblies are also disclosed.
