Abstract:
A monolayer polymeric film comprising a mixture of a structural polymeric material and a second polymeric material, said second polymeric material including a printable material, wherein the monolayer polymeric film is formed by mixing said structural polymeric material and said second polymeric material together without an additional coupling additive to form a unitary mixture, stretching said unitary mixture, heat stabilizing said unitary mixture on one or more heat stabilization rollers at a temperature sufficient to cause a portion of said printable material of said second polymeric material to bloom to a surface of said unitary mixture, wherein said structural polymeric material is selected from the group consisting of polyethylene, polypropylene and a polyethylene-polypropylene copolymer and said secondary polymeric material is selected from the group consisting of ethyl-vinyl-acetate copolymer and ethyl-methacrylate copolymer, and wherein the steps associated with forming the monolayer polymeric film include restricting shrinkage of said unitary mixture in a transverse direction.
