Abstract: Bio-degradable, high-barrier packaging materials and methods for production are provided. The present high-barrier packaging materials include a substrate having a print side and a back side, a coating having nano pigments on the print side and a metalized film applied to the back side with a binding layer. Preferably, at least one of the metalized film and the binding layer includes polylactic acid. Moreover, the back side preferably also includes a polylactic acid heat seal layer.

Abstract: A multifunctional identification label comprises a paper substrate formed from a cellulose furnish including 1 to 2.5 percent of a wet strength resin and a rosin size. A front side of the substrate is machine glazed, coated with a print receptive coating, and printed with a bar code. The back side of the substrate has a coating comprising one or more pigments selected from the group of clay, magadite and mixtures thereof, a binder, and 1 to 2.5 parts by dry weight of pigment of a salt. A conductive ink antenna is printed on the back side coating. A RFID chip is secured to the back side of the coated substrate and electrically connected to the antenna. Embodiments of the invention include a pressure sensitive adhesive label including RFID and bar code identification, a ticket adapted for printing on both sides incorporating RFID identification, and an RFID insert.

Abstract: A paper coating includes a combination of a primary pigment and a secondary pigment. The primary pigment includes anionic particles having a particle size distribution where at least 96% of the particles by weight have a particle size less than 2 microns. The secondary pigment is a cationic, grit-free pigment having an average particle size of 3 microns or less. The coating also includes up to 17 weight % of a hydrophilic styrene-butadiene latex based on the weight of the dry pigments and a co-binder. Another embodiment of this invention is a coated base sheet that includes a base sheet to which the above coating has been applied.

Abstract: A method of producing the low glare, high print gloss paper of the invention comprises the steps of providing a paper substrate, coating the substrate with an aqueous coating composition having, as a dry parts by weight per 100 parts of pigment, 50-90 parts coarse delaminated clay pigment having a particle size of 8-12 microns and 10-20 parts calcium carbonate having a particle size of between 0.7 and 1.1 microns, drying the coating; and supercalendering the coated substrate with at least two passes per side with rolls having a surface roughness of 90-130 Ra. The step of supercalendering imparts a Parker Print-Surf roughness of 1.7-2.2 microns and a sheet gloss of about 25-30. Four color printing produces a print gloss of 65-70 and a delta gloss of at least 38.

Abstract: A recording medium particularly suitable for electrophotographic copying is characterized by coated paper that for a given basis weight has proportionally less coating and proportionally more fiber than conventional coated paper made for electrophotographic processes. The base sheet of the coated paper is preferably formed square on a paper machine wet end and has on the order of 40-50% less filler than conventional sheet paper made for electrophotographic processes. After being formed and dried, the base sheet is provided with a top coat weight that is approximately 60% less than the typical coat weight used for conventional paper. The coating is formulated to have sufficient viscosity to stay more on the surface of the base sheet. The coated sheet is calendered to a medium gloss on the order of a 75° TAPPI gloss of about 45, both to preserve a degree of surface roughness to enhance runnability of the paper through an electrophotographic copier and to provide a pleasant and easily readable surface.
