A flexible packaging material including: a core portion having a geometrically patterned structure defining two spaced-apart substantially planar faces and providing air space therebetween, the core portion including cellulosic fiber-based walls having a core grammage; and at least one cellulosic fiber-based liner bonded to a respective one of the planar faces of the core portion and having a liner grammage lower than the core grammage, the material being flexible along a plane defined by the at least one liner.

A self supporting panel system used to fabricate ceilings, floors, walls, or roofs. The panel system is assembled from a plurality of panels, each having a core that is sandwiched between opposing plate members. In a preferred embodiment, the core of each panel includes a unifying material to enhance the load bearing capacity of the panel.

A laminated composite interior component includes a first member that has a predetermined mating surface; and a second member made of an elastically deformable resin material. The second member has a plate-shaped portion that is substantially parallel to the mating surface and that has multiple protrusions which are formed integrally with the plate-shaped portion and which protrude toward the mating surface such that a space is formed between the mating surface and the plate-shaped portion. The second member is arranged so as to be laminated on the first member with the protrusions in contact with the mating surface.

A flexible cellulosic fiber-based material including: a core portion having a geometrically patterned structure defining two spaced-apart substantially planar faces and providing air space therebetween, the core portion including cellulosic fiber-based walls having a core grammage; and at least one cellulosic fiber-based liner bonded to a respective one of the planar faces of the core portion and having a liner grammage lower than the core grammage, the material being flexible along a plane defined by the at least one liner.

A method for making a slip resistant mat can include assembling parts with predetermined geometries to form a mold that can be used for making slip resistant mats that have channels to account for moisture between the mat and the floor. The unique geometries of the parts which form the mold can be manufactured efficiently and with reduced costs. The mold of this invention can be used to make slip resistant mats with channels that can both dissipate water and offer a high degree of mat to floor surface contact.

A honeycomb structure element including an at least partially closed honeycomb structure, which is formed by joining at least two structured layers having honeycomb cells that are open on one side. A method for manufacturing a honeycomb structure element including forming an at least partially closed honeycomb structure by joining at least two structured layers having honeycomb cells that are pen on one side.

An air permeable sun shading fabric for provision of shade while allowing air to permeate the fabric includes a panel that is flexible and comprises a plurality of layers. The plurality of layers comprises an inner layer and an outer layer. Each of the layers has a plurality of openings. The openings are consistently sized and equally spaced, thus defining a band around each of the openings. The opening and a respective one of the bands define a unit. The openings of each of the layers are positioned in rows that are parallel. Each of the rows is offset by one half of the unit from adjacent rows. The layers are mutually coupled, such that each of the pluralities of openings is offset from the pluralities of openings positioned in adjacent layers.

A honeycomb structure element including an at least partially closed honeycomb structure, which is formed by joining at least two structured layers having honeycomb cells that are open on one side. A method for manufacturing a honeycomb structure element including forming an at least partially closed honeycomb structure by joining at least two structured layers having honeycomb cells that are open on one side.

A composite panel includes a honeycomb core sandwiched by a pair of skins that are attached directly to the core with no separate adhesive layer. The skins are impregnated with a resin material that is unevenly distributed between first and second surfaces, and direct contact is established between the surfaces with the greater resin distribution and the core, reducing weight and eliminating the manufacturing step of incorporating an adhesive layer therebetween.
