In some embodiments, the aqueous-based polymer coatings are surface-treated using corona treatment. Methods of making and using the same are also disclosed.

A heat-sealable barrier paper having a) a carrier substrate having a front side and a back side opposite the front side, b) optionally an interlayer comprising a binder and disposed on the front side of the carrier substrate, c) a first barrier layer comprising a crosslinked polysaccharide and disposed on the front side of the carrier substrate or, if there is an interlayer, on the interlayer, d) a second barrier layer, disposed on the first barrier layer and consisting of or comprising i) an acrylate copolymer and/or ii) a wax based on a vegetable oil, the use of a barrier paper for packaging products, a method for heat-sealing a barrier paper, and to a method for producing a barrier paper.

A method including providing a substrate including a substrate surface with a first surface free energy; treating one or more sections of the substrate surface by applying a coating including an ink and/or at least one ink component; and applying a wax coating to at least one of the one or more treated sections of the substrate surface, in which the wax coating has a second surface free energy and the coating including the ink and/or ink component has a third surface free energy that is greater than the second surface free energy such that adhesion of the wax coating to the treated sections of the substrate surface is increased. Also provided is an article formed from a treated substrate.

According to an example aspect of the present invention, there is provided a cost-effective method of producing cellulose based films by introducing an intense water removal system to the process, and cellulose based films thereof having improved properties.

Coatings for packaging materials and, more specifically, aqueous coatings for paperboard substrates and methods of applying the coatings. The aqueous coatings may include light blocking particles.

A coated paperboard container includes a paperboard substrate and an aqueous barrier coating on the paperboard substrate. The coated paperboard container has a repulpability yield of 75% accepts or greater, a sidewall seam bond strength of 30 pounds per inch or greater, and a wet rigidity loss of 50% or less.

Padded materials and corresponding systems and methods for forming the same are provided herein. A padded material comprises a first web of paper-based material defining a first and a second surface, and a second web of paper-based material defining a first and a second surface. A first layer of heat seal coating is disposed on the second surface of the first web, and a second layer of heat seal coating is disposed on the second surface of the second web. A starch-based padding is sandwiched between the first web and the second web such that the starch-based padding is positioned between the first surface of the first web and the second layer of heat seal coating disposed on the second surface of the second web. The padded material may be formed into a roll stock that is used in an automated packaging machine, such as an automated mailer formation device.

The present invention includes a label, a label sheet and a method for manufacturing the label. The label includes a paper facestock having first and second surfaces and a layer of pressure sensitive adhesive proximal to the second surface. The label can be adhered to a substrate having pre-applied indicia to cover the indicia and the label is opaque enough to prevent the viewing of the covered indicia while matching the color of the substrate.

A method for manufacturing a compostable plate which comprises: a step of manufacturing a supporting layer made of compostable cardboard; a step of printing at least one portion to be printed of the supporting layer made of compostable cardboard in order to obtain at least one respective printed portion, the step of printing being carried out using compostable inks; a step of spreading, at least over the surface that defines the at least one printed portion, a compostable biopolymer in order to provide a protective layer; a step of forming in order to provide a compostable plate, the step of forming comprising a thermoforming by insertion, between a male mold part and a female mold part, of the supporting layer which has the printed portion or portions and the protective layer.

The present invention relates to a method for manufacturing a barrier-coated substrate web, coated with a layer of reduced graphene oxide. The invention further relates to laminated packaging materials comprising the barrier-coated substrate web, in particular intended for liquid carton food packaging, and to liquid carton packaging containers comprising the laminated packaging material.
