20230046635 · 2023-02-16 · ·

The present invention relates to a multilayered cellulose-based substrate, comprising a cellulose-based first layer, and a cellulose-based second layer in contact with said first layer, wherein said substrate has a basis weight above 85 g/m.sup.2, wherein said first layer comprises an internal sizing agent, and wherein said second layer has been subjected to grafting with a fatty acid halide through the entire thickness of said second layer. The invention further relates to a method for manufacturing the multilayered cellulose-based substrate.

Composite cellulose material obtained from coffee husks or cocoa shells, an article comprising same and a method for producing said material

The present invention relates to the production of cellulose from coffee or cocoa husks. The cellulose extracted can be used to produce paper, card stock, and cardboard. In addition, a composite material also comprising a material that allows the release of aromas is manufactured using said cellulose. Said material is used to manufacture a laminated product for use in primary, secondary and tertiary packaging applications. Said type of article allows printing on the outer surface thereof, is biodegradable and biocompatible.

TISSUE PRODUCT AND METHOD AND APPARATUS FOR PRODUCING SAME

A multi-ply tissue paper product includes at least three plies. The tissue paper product includes a first inner ply being a creped ribbed ply and having a basis weight of 10 to 30 gsm, and a first outermost ply and a second outermost ply on each side of said inner ply, the first and second outermost plies being non-ribbed plies, wherein a creped ribbed ply is a ply including ribs and valleys providing an average core roughness Rk in the range 10 to 300 μm, and peaks being 4 to 12 per cm as measured along said first direction; and wherein a non-ribbed ply is a ply displaying no parallel ribs and valleys extending continuously along any direction of the ply or displaying parallel ribs and valleys extending continuously along any direction of the ply, the ribs and valleys providing peaks being less than 4 per cm.

Thermal insulation liners

Provided herein are products, methods, and kits, for use in regulating the temperature of an object. The present invention relates to thermal insulating liners for regulating the temperature of perishable goods or temperature sensitive products. The thermal insulating liners generally may be dimensioned to fit within a container. The thermal insulating liners may be quickly collapsed and reconstructed to improve stackability and diminish the amount of space required to store the thermal insulating liners prior to use.

WRAPPED PAPERBOARD PACKAGING
20230001682 · 2023-01-05 ·

A packaging structure and methods of manufacturing a packaging structure. The packaging structure, for example, an edge protector, a corner board, etc., may generally include a first ply having a first width, a second ply having a second width, and a third ply having a third width wider than the first width and the second width. The second ply may be wrapped around at least one end of the first ply, and the third ply may be wrapped around the first ply and the second ply. The third ply may overlap at a portion (e.g., an intermediate portion, an apex, etc.) of the packaging structure.

Absorbent structures with high absorbency and low basis weight

Absorbent product including a laminate of at least two plies, wherein the absorbent product has a measured Valley Volume parameter greater than 11 microns and a Pit Density of greater than 25 pockets per sq. cm.

LIGHT WEIGHT LINERBOARD FOR CORRUGATED BOARD

The invention relates to a method to produce a linerboard exhibiting a high bending resistance and a high compression strength, which in turn provides high resistance to interflute buckling and sagging in a thereof formed corrugated board. This is achieved by the inventive combination of an optimized fiber refining level of the furnish in each layer of the linerboard, the separate formation of the top layer and the use of a multi-layer headbox to form the two-layered ply. In addition, the linerboard made according to the invention provides good printing properties in a thereof produced corrugated board, especially in flexographic printing, without the fluting structure being negatively affected.

Methods of making fibrous structures with shaped polymer particles

A fibrous structure comprising first and second plies. The first ply comprises a first textured substrate comprising a first side comprising first discrete regions and a first continuous region extending between the first discrete regions, each first discrete region comprising an outer section and sidewall sections extending outwardly from the adjacent first continuous region to the outer section; a second side comprising first discrete portions corresponding to the first discrete regions and a first continuous portion corresponding to the first continuous region; and first polymer particles deposited on at least one of the first side or the second side. When the first polymer particles are deposited on the first side, the first polymer particles are substantially deposited on the outer sections of the first discrete regions and do not extend to the adjacent first continuous region. When the first polymer particles are deposited on the second side, the first polymer particles are substantially deposited on the first continuous portion and do not extend to the adjacent first discrete portions. At least a section of each of the first polymer particles defines a raised edge. The second ply comprises a second substrate joined to the first textured substrate.

Process for making a multi-ply dispersible wipe

A process for making a multi-ply dispersible wipe includes providing a first web and a second web, each web comprising cellulose fibers; superposing the first web over the second web; applying an aqueous solution to at least the first web; after the aqueous solution is applied to the first web, crimping the second web to the first web to create a composite web; cutting or perforating the composite web to define a plurality of multi-ply wet wipes; and packaging the composite web/wet wipes into a package.
