Abstract
An imageable article includes a backside filled resin layer bonded to a back side of a paper substrate. The backside filled resin layer includes: resin selected from the group consisting of low density polyethylene (LDPE), and a combination of low density polyethylene (LDPE) and high density polyethylene (HDPE); and a filler selected from the group consisting of calcium carbonate, zeolite, silica, talc, alumina, aluminum trihydrate (ATH), calcium silicate, kaolin, calcined clay, and combinations thereof. The backside filled resin layer further includes from approximately 3 weight % to approximately 60 weight % of the filler.

- and a filler selected from the group consisting of calcium carbonate, zeolite, silica, talc, alumina, aluminum trihydrate (ATH), calcium silicate, kaolin, calcined clay, and combinations thereof;
- wherein the backside filled resin layer includes from approximately 3 weight % to approximately 60 weight % of the filler.
A method of coating a paper substrate with a filled resin layer, comprising the steps of:
- extruding a backside filled resin layer onto a back side of a paper substrate;
- wherein the backside filled resin layer includes:
- resin selected from the group consisting of low density polyethylene (LDPE), and a combination of low density polyethylene (LDPE) and high density polyethylene (HDPE);
- and a filler selected from the group consisting of calcium carbonate, silica, talc, alumina, aluminum trihydrate (ATH), calcium silicate, kaolin, calcined clay, and combinations thereof;
- and wherein the backside filled resin layer includes from approximately 3 weight % to approximately 60 weight % of the filler.
A system for coating one or both sides of a paper substrate with a filled resin layer, comprising:
- a paper substrate;
- and
- a resin layer extruder for extruding a filled resin layer bonded to a back side of a paper substrate;
- wherein the filled resin layer includes:
- resin selected from the group consisting of low density polyethylene (LDPE), and a combination of low density polyethylene (LDPE) and high density polyethylene (HDPE);
- and a filler selected from the group consisting of calcium carbonate, silica, talc, alumina, aluminum trihydrate (ATH), calcium silicate, kaolin, calcined clay, and combinations thereof;
- and wherein the filled resin layer includes from approximately 3 weight % to approximately 60 weight % of the filler.
