Abstract: Bags are formed from reclaimed plastic material. Each bag comprises two opposed sheet sections formed substantially entirely of a first plastic type, but also containing impurity particles of a different plastic type. The sheet sections comprise at least two distinct independent layers, with each layer in each sheet section being surface bonded to each adjacent layer in that sheet section. Although discontinuities in each layer resulting from the impurity particles create weak areas and in some cases apertures, the weakened portions of each layer are reinforced by portions of the other layer that are not weakened, since there is a minute likelihood that an impurity particle in one layer will be precisely co-located with an impurity particle in an adjacent layer. Thus, each layer reinforces the other layer to maintain structural integrity of the sheet section and of the bag. Methods for forming such bags are also described.
