Abstract:
Disclosed is a composite wood component having upper and lower surface layers and a core layer; a first glueline layer; a second glueline layer; and an overlay layer.
Abstract:
The present invention is directed to monolayer, bi-layer, and multilayer films made from fruit, vegetable or a combination thereof, which films have the thinness, strength, flexibility, and crispness to serve as alternates or substitutes for seaweed-based films such as nori, while providing the nutrition and flavor of fruits and vegetables. The films are useful for wrapping around a multiplicity of foods, and can be used to provide wrapped foods, including for example, fruit and vegetable wrapped sushi and onigiri.
Abstract:
A method of using a water-based boron-containing suspension as a source of boron additive is disclosed. The method includes adding the suspension into a mixing or reaction zone during the preparation of starch-based adhesives. The suspension includes a boron compound and at least on suspension aid.
Abstract:
Articles containing cellulose materials and treated with a chemical additive are disclosed. In accordance with the present invention, at least a portion of the cellulose containing the article is modified to include a first moiety. A chemical additive, such as softener or a humectant, is then chosen that includes a second moiety. When the chemical additive is applied to the article, the second moiety on the chemical additive forms a chemical linkage with the first moiety on the cellulose material. In this manner, the chemical additive becomes bonded to the cellulose material alleviating problems associated with retention. In one embodiment, the present invention is directed to the formation of tissue products, such as facial tissue, bath tissue and paper towels.
Abstract:
An aqueous adhesive composition with good release properties. A preferred embodiment comprises sodium lauryl sulfate and a modified tapioca dextrin.
Abstract:
A method for not only preserving cellulose material from deterioration and from fire, but also for producing plywood, chip and particle board with an inexpensive and environmentally acceptable adhesive is described. The cellulose material is processed by spraying, immersing or being subjected to vacuum and pressure application in two steps. One step processes the cellulose material with a sodium silicate preservative solution. Another step processes the cellulose material with a gaseous carbon dioxide. Pressure application, moreover, can be varied in a range not to exceed 250 psi to improve product quality. Moistened cellulose material, treated in the foregoing manner, is coated with a comminuted protein, e.g. soybean meal, and pressed into a cellulose product, typically plywood and chip board.
Abstract:
There is described a label comprising a self supporting sheet of a biopolymer (preferably cellulose (e.g. regenerated cellulose), cellulose acetate and/or PLA) said sheet being substantially transparent to visible light when uncoated characterised in that the sheet comprises: (a) a first coating on at least one surface thereof to aid printability thereon; (b) a second coating comprising an adhesive dispersible in an aqueous medium; and (c) optionally a third coating to modify water permeability through the sheet. The labels are to be applied to articles such as glass containers. Preferred labels are wet glue cellulose labels for example where the first coating also comprises a copolymer of vinyl chloride and vinyl acetate to aid water permeability and hence rapid drying of the label on an article.
Abstract:
A method of disposing of a biodegradable plastic comprises the step of exposing the biodegradable plastic to a hot alkaline solution. The biodegradable plastic is a polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units wherein the first randomly repeating monomer unit has the structure: wherein R is H or a C1-2 alkyl, and n is 1 or 2; and the second randomly repeating monomer unit has the structure: wherein R is a C3-19 alkyl or a C3-19 alkenyl. At least 50% of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit.
Abstract:
The invention relates to a method of producing a laminated packaging material (10) including a core layer (16) of paper or paperboard and a barrier layer (14) applied on one side of the core layer. The invention also relates to a laminated packaging material (10) produced according to the method, as well as a packaging container (50) which is produced from the laminated packaging material (10).
Abstract:
A biodegradable molded plastic obtained by molding a mixture comprising the following ingredients: (A) 98 to 59 wt.% biodegradable plastic, (B) 1 to 40 wt.% dry powder of fibers swelling in water, and (C) 1 to 40 wt.% fertilizer powder (provided that the sum of (B) and (C) is 2 to 41 % by weight). In the composition, the biodegradable plastic has improved biodegradability and the rate of biodegradation can be controlled.
