The present invention relates to a haemostatic patch comprising a porous layer based on oxidized cellulose and a neutralized film based on chitosan, said film comprising a free face and a face fixed on one of the faces of the porous layer, and to the method of preparing said patch comprising the following steps: a) preparing a porous layer based on oxidized cellulose, b) preparing a film based on chitosan starting from an acidic aqueous solution of chitosan, c) fixing the film obtained in b) on one face of the porous layer, d) neutralizing the film obtained in b), where step c) can be carried out before or after step d), characterized in that: the neutralizing step d) comprises treatment of said film with a neutralizing composition comprising at least ethanol and ammonium hydroxide (NH.sub.4OH).

The inventive concept relates to a laminated film and a method of laminating films, and the disclosed laminated film includes at least two films sequentially stacked and bonded to each other, wherein each of the films may be each independently a gastric film or an enteric film.

A low-carbon insulative foam board includes an agricultural product mixed with petroleum-derived polymer foam. The foam board exhibits insulation, durability, and mechanical properties substantially similar to a foam board without the mixed agricultural product. In an embodiment, a polyisocyanurate board includes bubble walls carrying milled biomass, which displaces a portion of the polyisocyanurate.

Methods for making phenolic resins modified with one or more monosaccharides and methods for making composite products therewith are provided. In at least one specific embodiment, a method for making a composite product can include contacting a plurality of cellulosic sheets with a resin composition that includes a phenolic resin and a monosaccharide. The resin composition can include about 0.5 wt % to about 30 wt % of the monosaccharide, based on a combined weight of the phenolic resin and the monosaccharide. The method can also include at least partially curing the resin composition to produce a composite product.

The present invention is to provide a full-frame adhesive anti-fog film structure, comprising: an anti-fog film, which has a front side and a back side opposing the front side; and an adhesive, which is disposed at an edge of the back side and arranged along the edge so as to be frame-shaped. The anti-fog film of the present invention is attachable to a planar, cylindrical or spherical lens through the full frame-shaped adhesive so that not only can the anti-fog film be fully attached to the lens but the full attachment of film also prevents bubbles from forming between the two attached surfaces. Also, an airtight space is formed between the full-frame adhesive anti-fog film structure and the lens to stop heat transfer and prevent fog from being formed, so as to not only provide good vision to users but also reduce the chance that the user will fall prey to an accident if the user's view is blocked.

A method of making a sandwich-type composite panel having a cellulose-based core and a living hinge from a stack of material is provided. The stack includes first and second reinforced thermoplastic skins, first and second sheets of thermoplastic adhesive and a cellulose-based cellular core disposed between the sheets and the skins. A pressure is applied to the stack after heating the stack wherein the skins are bonded to the core by the sheets to form the composite panel. A portion of the composite panel is crushed at a predetermined location simultaneously with applying the pressure to locally compact and separate the cellular core at the predetermined location to form two side portions of the panel. The heated first skin stretches during the step of crushing while remaining intact between the two side portions. The skins bond together at the predetermined location to form the living hinge.

Provided is a laminated glazed unit having at least one first glass substrate and a second glass substrate, at least one functional film arranged between the two glass substrates, at least one first lamination interlayer film between the first glass substrate and the functional film, and at least one second lamination interlayer film between the second glass substrate and the functional film. The functional film has at least one layer of a transparent adhesive material, referred to as OCA, which is viscoelastic so as to be deformable in its thickness during the process for laminating the glazed unit.

This method includes the arrangement of a first sheet (22A) of porous material on a first face (18) of a base layer and of a second sheet (22B) of porous material of a second face (20) of the base layer before a heating step. Each sheet (22A, 22B) of porous material has a thickness of less than that of the formed layer (16). The sheets (22A, 22B) of porous material confine between them the molten polymeric material derived from the heat fusible polymer fibers during the heating step. The sheets (22A, 22B) of porous material are bound to the formed layer (16) after the step for building up the formed layer (16), in order to make up a first composite body (12A).

A laminate includes a core structure having a first surface and a second surface, the core structure including an elastic core layer and a plastic core layer, wherein the elastic core layer is one of a film, a plurality of strands, and a plurality of strips, and wherein the plastic core layer is one of a film layer, a plurality of strands, and a plurality of strips, the plastic core structure reinforcing the core layer in the machine direction, and a nonwoven first facing layer affixed to the first surface.

The present invention relates to a paper-based packaging material which is an eco-friendly alternative to plastic packaging. The packaging material of the present invention that is recyclable and reusable but also providing the necessary oxygen. moisture, aroma and grease barrier features to keep the freshness of food for prolonged periods like in the case of packaging those made from the fossil sources or even superseding them.
