METHOD AND APPARATUS FOR THE PRODUCTION OF A PLANAR CUSHIONING MATERIAL MADE OF PAPER, AND A CUSHIONING MATERIAL
20230211594 · 2023-07-06 ·

An application mechanism is used to apply water to wet paper in a process for producing planar cushioning material and filler material made of paper having a spatial structure with embossing on each side. The water can be applied to the paper like ink, so as to keep it sufficiently moist for the embossing process. Likewise, it is possible to use ink to apply a two-dimensional imprint, whereby sufficient wetting can also take place, but at the same time an optical effect is achieved.

Laminated parts containing a slip resistant and water resistant outer layer and methods for their production
11548244 · 2023-01-10 · ·

Laminated parts are described that include a core, a fiber layer arranged on each side of the core and impregnated with a polyurethane resin, and an outer layer that at least partially coats at least one of the polyurethane impregnated fiber layers, in which the outer layer is the cured reaction product of a reaction mixture that includes: (1) a polyisocyanate, (2) a polyether polyol having a molecular weight of 800 Da to 25,000 Da and a functionality of 2 to 8, and (3) a fatty acid ester having isocyanate-reactive functionality. Methods of producing such laminated parts are also described.

20230002974 · 2023-01-05 ·

A gypsum wallboard panel comprises: a gypsum core; and a paper cover sheet disposed on the gypsum core, the paper cover sheet comprising pulp fiber and an uncooked starch in an amount of at least 2% by weight of the pulp fiber.

Low outgassing clean adhesive

Provided herein is a solvent-based pressure sensitive adhesive comprising a polymer comprising a vinyl acetate monomer, an acrylic ester monomer, and a monomer having hydroxyl or amine functionality. The adhesive also comprise a crosslinker. The coated and dried adhesive has outgassing of less than 2000 ng/cm.sup.2, even when applied to an electronic device that is operated at elevated temperature.

Flat-Shaped Composite Material, Package Sleeve and Package With Trapezoidal Gable

A flat-shaped composite material is represented and described for manufacturing a package, including: a polymer outer layer, a polymer inner layer, a fibrous support layer, which is arranged between the polymer outer layer and the polymer inner layer. The flat-shaped composite material has a plurality of fold lines, which are arranged and designed such that a closed package can be manufactured by folding the flat-shaped composite material along the fold lines and by connecting seam surfaces of the flat-shaped composite material and a sleeve surface. The sleeve surface includes a front surface, a first side surface, a second side surface, a first rear surface and a second rear surface, and base surfaces. The base surfaces include triangular base surfaces and quadrangular base surfaces and gable surfaces. The gable surfaces include triangular gable surfaces and quadrangular gable surfaces. The base surfaces and the gable surfaces are arranged on opposite sides of the sleeve surface. In order to enable the manufacture of packages with even more complex geometries even in the gable and base region, at least one quadrangular gable surface is provided with two small gable surface angles, which are smaller than 90°, with two large gable surface angles, which are greater than 90°, and with an angle sum, which is greater than 360°. A package sleeve made of a composite material and a package manufactured from the composite material or from the package sleeve are also represented and described.

Inverted Tabbed Induction Liner
20220410545 · 2022-12-29 ·

Various forms of tabbed sealing members are described along with the laminates from which the sealing members are formed. In some forms, the tabbed sealing members may be considered inverted tabbed sealing members for induction sealing as the induction heating layer is provided in the upper laminate instead of the lower laminate. In this regard, the induction heating layer is positioned further from the heat seal, contrary to conventional tabbed sealing members.

Recyclable Hemp Composition and Uses in Container Manufacturing
20220411154 · 2022-12-29 ·

The present invention relates to a cardboard container made from three layers including recyclable hemp paper. The hemp paper has a novel composition comprised of hemp infused pulp, hemp strands, and hemp fiber to add reinforced strength. The three layers include an outer liner of hemp paper, a wavy layer of the hemp paper, and an inner layer of plane hemp paper. The cardboard box is configured to replace conventional tree paper containers or boxes and can be made in various shapes and sizes. The hemp paper composition reduces the number of trees being cut down and landfill waste due to non-recyclable materials being thrown away. The container of the present invention can be recycled and provides an environmentally conscious option for users.
