In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.

Panel for sheathing system and method

The panel includes a water resistant barrier layer secured atop its outward facing surface. The water resistant barrier layer includes a skid resistant surface. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. A method for manufacturing the water resistant building panels is also disclosed and includes the steps of feeding paper onto a forming belt, depositing lignocellulosic material and the binding agent onto the forming belt so as to form a lignocellulosic mat, applying heat and pressure so as to impart the skid resistant surface on the paper, and cutting panels to predetermined sizes.

A PACKAGING MATERIAL FOR PACKAGING OF LIQUID AND FOOD
20230212825 · 2023-07-06 · ·

The invention discloses a paperboard for packaging of a heat-sealable packaging material comprising: —a paperboard substrate comprising a first and a second side, —a first and an optional second dispersion coating layer on the first side, which first and optional second dispersion coating layer provides a barrier against at least one of liquid, moisture, grease and gas, —an extrusion coated barrier layer comprising a polyolefin, wherein the first and optional second dispersion coating layer is applied between the paperboard substrate and the extrusion coated barrier layer, and wherein the coat weight of the extrusion coated barrier layer is less than 15 gsm. The packaging material according of the invention minimizes the amount of plastic coating, but still provides the needed barrier properties for the packaging of food and/or liquid. The packaging material has especially been shown to provide a longer shelf life for food items packed in a packaging made from the material. Especially, the packaging material provides gas-, liquid and/or grease barrier properties. Although the packaging material comprises such low amount of extruded thermoplastic polymers, the material is readily heat-sealable.

LIGHT ABSORPTION ANISOTROPIC FILM, LAMINATE, AND IMAGE DISPLAY DEVICE

Provided is a light absorption anisotropic film capable of preparing an image display device having excellent display performance and excellent durability, and a laminate and an image display device formed of the light absorption anisotropic film. The light absorption anisotropic film is used for an image display device, which is formed of a liquid crystal composition containing a liquid crystal compound and a dichroic substance, in which in a signal derived from the dichroic substance detected by time-of-flight secondary ion mass spectrometry, a relationship between a maximum intensity Imax of the light absorption anisotropic film in a thickness direction and an intensity Isur1 in a surface of the light absorption anisotropic film on a viewing side of the image display device satisfies Expression (I-1) 2.0≤Imax/Isur1.

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.
