Abstract: A cross-linked thermoplastic polyurea is formed by heating a mixture containing a thermoplastic urethane base material, a monomeric and/or polymeric di-isocyanate comprising between 1 to 10% of the total weight of the mixture, and a diamine comprising between 1 to 10% of the total weight of the mixture. A thermoplastic polyurethane may be formed by substituting hydroquinone for the diamine. The mixture is heated to a temperature within the range of 250° F. to 550° F. The heated mixture, which is flowable, is then injected into at least one injection molding device. The mixture is then cured at a temperature between 150° F. to 250° F. for a period of time between 2 and 36 hours. The cross-linked thermoplastic polyurethane/polyurea retains the excellent flowability characteristics of a thermoplastic urethane while the same time exhibits good abrasion, tensile strength, rebound, and compression set characteristics which are similar to those found in thermoset urethanes.

Alternatively, a COC polymer with Tg in the range 30 to 55° C. may be coextruded with other thermoplastic polymer or polymer films in a coextrusion process to form a heat sealable film. The film of the invention is suitable for packing foods or other consumable items.
