PAPERBOARD STRUCTURE WITH AT LEAST ONE BARRIER COATING LAYER
A paperboard structure that includes a paperboard substrate which includes a first major side and a second major side along with at least one barrier coating layer on the first major side. The barrier coating layer(s) may include a binder and a pigment, wherein the binder has a glass transition temperature of at least 20° C., wherein a ratio of the binder to the pigment is at least about 1:2 by weight.
Paperboard structure with at least one barrier coating layer
A paperboard structure that includes a paperboard substrate which includes a first major side and a second major side along with at least one barrier coating layer on the first major side. The barrier coating layer(s) may include a binder and a pigment, wherein the binder has a glass transition temperature of at least 20° C., wherein a ratio of the binder to the pigment is at least about 1:2 by weight.
Smooth and low density paperboard structures and methods for manufacturing the same
A method for manufacturing a paperboard structure includes passing a paperboard substrate through a hot-hard calender to yield a calendered paperboard substrate, the hot-hard calender including a nip defined by a thermo-roller and a counter roller, wherein a contact surface of the thermo-roller is heated to an elevated temperature. The method then includes applying a basecoat to the calendered paperboard substrate to yield a basecoated paperboard substrate, the basecoat includes a basecoat binder and a basecoat pigment blend. The method further includes applying a topcoat to the basecoated paperboard substrate.
Moisture barrier coated tobacco product packaging
Provided herein is a cigarette pack formed of a moisture barrier coated paper material. The paper material includes a base substrate, a first polymer coating, a second polymer coating, and a third polymer coating. The first polymer coating, the second polymer coating, and the third polymer coating provide a barrier for moisture and air exchange through the paper material. The first polymer coating, the second polymer coating, and the third polymer coating also provide heat and pressure sealability capabilities to the paper material.
Method for manufacturing a packaging material and a packaging material made by the method
The invention relates to a method of manufacturing a heat-sealable packaging material, the method comprising the steps of: providing a paperboard substrate comprising a top ply, applying a first dispersion barrier layer on the top ply, wherein the first dispersion barrier layer comprises a latex having a first glass transition temperature, and applying a second dispersion barrier layer on the first barrier layer, wherein the second dispersion barrier layer comprises a latex having a second glass transition temperature, wherein the second glass transition temperature is higher than the first glass transition temperature, wherein the grammage of the second dispersion barrier layer is lower than the grammage of the first dispersion barrier layer, and wherein the second dispersion barrier layer comprises pigments. The invention further relates to a respective heat-sealable packaging material.
Recording medium
According to an example, a recording medium may include a substrate; a first coating including an inorganic pigment, a first binder, and a fixative agent; and a second coating including inorganic nanoparticles and a second binder; in which the inorganic pigment may be a plate-shaped pigment.
HEAT-SEALABLE PAPERBOARD STRUCTURES AND METHODS
A heat-sealable paperboard structure including a paperboard substrate having a first major side and a second major side opposed from the first major side, a heat-sealable barrier coating on the first major side of the paperboard substrate, and a top coat positioned over the heat-sealable barrier coating, wherein the top coat forms a discontinuous layer over the heat-sealable barrier coating.
COATED PAPER AND PAPERBOARD STRUCTURES
A coated paper or paperboard structure includes a paper or paperboard substrate and a basecoat applied to the paper or paperboard substrate to yield a basecoat outer surface. The basecoat includes a water-soluble polymer binder and pigment.
METHOD OF PRINTING COLOURED PAPER
A method of manufacturing dyed paper, following a request for paper coloured in a specific Pantone®, the method comprising the steps of selecting coloured paper from an available supply which is dyed in a colour that is in the same colour category as the Pantone®, applying a white primer coating to at least one side of the selected paper, applying a layer of printable coating over the white primer coating; and printing a layer of the Pantone® colour requested on at least part of the printable coating.
Decorative material
In a decorative material, a matting agent is added to, of a first gloss-adjusting layer and a second gloss-adjusting layer, one with lower gloss, where the matting agent has a particle diameter of 1.0 times or more the thickness of the gloss-adjusting layer with lower gloss. Accordingly, sufficient unevenness can be imparted to the surface of the gloss-adjusting layer; thus, glossiness does not increase in oblique observation, and low gloss can be maintained. Therefore, it is possible to provide a decorative material having a feeling of unevenness obtained by the difference in gloss that hardly changes even when observed obliquely.
