Abstract

A reinforced two-side-printable laminate material constructed of a top layer of coated-one-side paper or related material, a middle layer of foamed polypropylene film or related material, and a bottom layer of paper material, said bottom layer being coated with a direct thermal emulsion with the thermal emulsion facing outward.

Claims

1. A material for making tags printable on two sides, said material comprising a laminate with a top face and a bottom face, said laminate comprising a top layer of paper material, said paper material comprising a coated-one-side paper, with the coated side of the paper comprising its top surface, said top layer having a thickness between about 2 to 4 mils;

a middle reinforcing layer of foamed polypropylene film, said middle layer bonded to the bottom surface of the top layer by a layer of bonding adhesive applied between the top surface of said middle layer and said bottom surface of said paper top layer, said middle reinforcing layer having a thickness between about 1 to 6 mils;

a bottom layer of paper material, said bottom layer having been coated with a direct thermal emulsion, with said thermal emulsion facing outwardly so that it remains exposed, said bottom layer bonded to the bottom surface of said middle layer by a layer of bonding adhesive applied between the top surface of said bottom layer and said bottom surface of said middle layer, said bottom layer having a thickness between about 2 to 5 mils; and

said bonding adhesive being a water based laminating adhesive.

2. The material of claim 1, wherein the middle layer also includes a polymer film of polyethylene.
