  • Patent number: 10435841
    Abstract: The present invention provides a pulp product (e.g., paper) comprising cellulose and nanocellulose, wherein the nanocellulose is derived from the cellulose in a mechanical and/or chemical step that is separate from the main pulping process. The pulping process may be thermomechanical pulping or hydrothermal-mechanical pulping, for example. The pulp product is stronger and smoother with the presence of the nanocellulose. The nanocellulose further can function as a retention aid, for a step of forming the pulp product (e.g., in a paper machine). Other embodiments provide a corrugated medium pulp composition comprising cellulose pulp and nanocellulose, wherein the nanocellulose includes cellulose nanofibrils and/or cellulose nanocrystals and the nanocellulose may be hydrophobic. The nanocellulose improves the strength properties of the corrugated medium. In some embodiments, the cellulose pulp is a GreenBox+® pulp and the nanocellulose is derived from the AVAP® process.

  • Patent number: 10428460
    Abstract: A porous body is placed in a rectangular parallelepipedal casing made of a stainless steel to prepare a mold form. A CNF-containing slurry is charged into the mold form, and another porous body is placed on the CNF-containing slurry. If the CNF-containing slurry are enwrapped in a nylon mesh, leakage of the CNF-containing slurry from a gap between the mold form and the porous body or clogging of the porous bodies can be inhibited. The upper and lower porous bodies are heated while applying a load to the CNF-containing slurry for a desired period of time to effect hot pressing, thereby obtaining a desired molded product. This provides a method for molding CNFs which enables a CNF molded product having a three-dimensional configuration to be obtained at a high productivity, and the CNF molded product obtained by the method for molding CNFs.

  • Patent number: 10383358
    Abstract: A rolling paper is formed according to a modified conventional paper-making process. The end product is infused with cannabinoids from an oil extract from the cannabis plant. Since paper-making is highly water intensive and the cannabinoid containing cannabis extract is an oil that is ordinarily immiscible in the water, an emulsifier is used to allow the cannabinoids to evenly disperse in the making of the paper. The addition of the cannabinoids and the emulsifier is done prior to the drying of the paper. Preferably, the emulsifier and cannabinoids are added during the sizing step of the paper-making. Preferably the emulsifier is a starch-like carbohydrate, a modified starch, more preferably hydroxy-propyl-methyl-cellulose. The cannabinoid containing cannabis extract can be added at the pulping, web-forming step and/or preferably at the sizing step of paper-making.

  • Patent number: 10344431
    Abstract: The invention relates to a security sheet or document having enhanced watermark(s). In one exemplary embodiment, the inventive security sheet or document is a single-ply paper that is made up of a paper layer including one or more watermarks, and a micro-optic security device (e.g., a patch or thread) that at least partially covers an upper or face portion of the watermark(s). The overlying patch or thread increases the durability of the watermark(s), thereby allowing for the watermark(s) as well as reduced fiber density areas therein to be made larger, and for the reduced fiber density areas to be made thinner. In a preferred embodiment, the micro-optic security device projects synthetic image(s) that coordinate or link in with the watermark design(s). In a more preferred embodiment, the micro-optic security device offers a machine detectable/readable feature in the form of enhanced IR-brightness, especially when measured in transmission.
