fig1 shows an embodiment of the zone - coated , poly coated paper ream wrap material 10 . fig1 depicts the inside web of the zone - coated , poly - coated ream wrap 10 that is typically 20 to 28 inches wide . the ream wrap is produced by extruding or otherwise coating paper with a layer of approximately 4 - 14 lbs . of polyethylene , low or high density polyethylene , or other polymer or poly resin across the entire inside web of the wrapper . typically , the basis weight of the underlying paper substrate comprises approximately 40 - 70 lbs . per 3 , 000 sq . ft . of white , brown , kraft or other paper . areas 20 and 25 depict the outer edges of the inside wrapper that are intended to overlap and form a heat - seal along the overlapped back panels of the packaging . areas 20 and 25 are typically ½ inch to 1½ inches in width and form the overlapped back panels of the wrapped product . areas 30 and 35 , typically 1 to 10 inches in width , comprise areas adjacent to the back panels that are covered with a varnish or other coating material intended to prevent heat - sealing of the poly coating to the bottom sheet ( s ) of paper encased in the ream . area 40 comprises the inside of the ream wrapper that consists of a layer of paper extruded with polyethylene or other polymer that is not zone - coated with the varnish or other coating . the present invention comprises a zone - coated , poly - coated ream wrapper 10 comprising paper extruded with polyethylene , low or high density polyethylene , or other polymer or poly resin , and a second layer of varnish or other coating material applied in zones adjacent to the overlapped back panel area of the packaging where a heat seal is intended to form . the extruded coating is applied across the entire inside web of the zone - coated , poly - coated ream wrapper 10 . areas 20 and 25 comprise the outer edges of the inside web of the ream wrap and constitute the overlapped back panel of the wrapper where a heat seal is intended to form during the wrapping process . areas 30 and 35 comprise the zone - coated areas approximately 1 to 10 inches in width that are covered with a varnish or other coating material that prevents heat - sealing in the areas adjacent to the overlapped back panel of the packaging where the heat seal is formed . the zone - coated varnish or other coating material is applied during the printing or other processes of the ream wrap production following the poly extrusion or coating process . area 40 comprises the inside ream wrap area that is not zone - coated after the poly extrusion or coating process described above . area 40 constitutes the remainder of the inside web that is not incorporated as part of the overlapped back panel forming the heat seal and that is outside of the zone - coated areas adjacent to the back panels . in a further embodiment , the method of producing the present invention comprises : extruding or coating a 4 - 14 lb . layer of polyethylene , high or low density polyethylene , or other polymer or poly resin onto a paper substrate comprising brown , white , kraft or other paper with a basis weight of approximately 40 - 70 lbs . the poly - coated paper is then passed through a printer , press , or other apparatus that applies a varnish or other coating material in specified 1 to 10 - inch zones along the length of the inside web of the ream wrapper 10 .
