Compositions and methods for manufacturing starch-based compositions

Compositions and methods for manufacturing sheets having a starch-bound matrix reinforced with fibers and optionally including an inorganic mineral filler. Suitable mixtures for forming the sheets are prepared by mixing together water, unmodified and ungelatinized starch granules, an auxiliary water-dispersible organic polymer, fibers, and optionally an inorganic mineral filler in the correct proportions to form a sheet having desired properties. The mixtures are formed into sheets by passing them between one or more sets of heated rollers to form green sheets. The heated rollers cause the auxiliary polymer to form a skin on the outer surfaces of the sheet that prevents the starch granules from causing the sheet to adhere to the rollers upon gelation of the starch. The green sheets are passed between heated rollers to gelatinize the starch granules, and then to dry the sheet by removing a substantial portion of the water by evaporation. The starch and auxiliary polymer form the binding matrix of the sheets with the fibers and optional inorganic filler dispersed throughout the binding matrix. The starch-bound sheets can be cut, rolled, pressed, scored, perforated, folded, and glued to fashion articles from the sheets much like paper or paperboard. The sheets are particularly useful in the mass production of containers, such as food and beverage containers.

Sheets having a starch-based binding matrix

Compositions and methods for manufacturing sheets having a starch-bound matrix, optionally reinforced with fibers and optionally including an inorganic mineral filler. Suitable mixtures for forming the sheets are prepared by mixing together water, unmodified and ungelatinized starch granules, a cellulosic ether, optionally fibers, and optionally an inorganic mineral filler in the correct proportions to form a sheet having desired properties. The mixtures are formed into sheets by passing them between one or more sets of heated rollers to form green sheets. The heated rollers cause the cellulosic ether to form a skin on the outer surfaces of the sheet that prevents the starch granules from causing the sheet to adhere to the rollers upon gelation of the starch. The green sheets are passed between heated rollers to gelatinize the starch granules, and then to dry the sheet by removing a substantial portion of the water by evaporation.

Storage mildew-proof and moth-proof packaging hemp cloth and preparation method thereof

The invention provides storage mildew-proof and moth-proof packaging hemp cloth and a preparation method thereof. The hemp cloth comprises green harmless storage protective agent and is prepared by taking common packaging hemp cloth as a material and adding 0.01-10wt% of storage protective agent. The preparation method comprises the following steps of: dissolving the storage protective agent in a solvent to prepare a solution, then impregnating the hemp cloth in the protective agent solution, removing the solution after the hemp cloth sufficiently absorbs the solution, and drying; or dissolving the storage protective agent in the solvent, then uniformly spraying the protective agent solution on the hemp cloth and drying the hemp cloth after the hemp cloth sufficiently absorbs the protective agent solution to prepare the storage mildew-proof and moth-proof packaging hemp cloth. The storage hemp cloth is used for packaging tobaccos or crops, can realize the whole process dynamic and real-time protection of the tobaccos, the crops and the like in purchase, transport and storage processes, protect products from mildew and moths, effectively prevent the mildew and the moths from spreading between bags and prevent the tobaccos, the crops and the like which are soaked by rain water from mildewing. Besides, the invention has an important function for reducing environment pollution and hidden safety danger which are caused by common technologies.

Bamboo shoot clothing packaging box and production process thereof

The invention relates to a packaging box, in particular to a bamboo shoot clothing packaging box which is formed by adopting bamboo shoot clothing (commonly called bamboo shoot shells, bamboo shells and indocalamus shells) made of moso bamboos (phyllostachys pubescens), phyllostachys parvifolia, dendrocalamus latiflorus, phyllostachys praecox, fargesia utilis, overlord bamboos and the like as raw materials (give priority to the moso bamboos) and processing through the processes of raw material purchasing and storage, rinsing, harmless treatment (insect control, mildew prevention, fiber softening, color development and mercerization), washing, drying, flattening, cutting, gluing (glue spraying or blanching and gluing), collage (blanching and collage), polishing, laser printing, inspecting, warehousing and the like. The bamboo shoot clothing packaging box has the main characteristics of moisture absorption and mildew prevention, insect control and corrosion resistance, stain repellence and scale prevention, is an ideal preferred package of tea leaves, tobaccos, food, instruments, jewelry and other products and has very extensive purpose; meanwhile, the bamboo shoot clothing packaging box is fashionable and attractive in appearance, realizes low carbon and environmental protection, is durable and fully embodies the change of wastes into valuables; moreover, a new high-quality laying and decoration material and a processing technology can be provided for the packaging industry in China.

Compositions for manufacturing fiber-reinforced, starch-bound articles having a foamed cellular matrix

Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a fiber-reinforced, starch-bound cellular matrix. Suitable mixtures used to form the articles are prepared by first preparing a viscous preblended mixture comprising water, a gelatinized starch-based binder, and fibers having an average length greater than about 2 mm. The highly viscous preblended mixture effectively transfers the shearing forces of the mixer to the fibers. The final moldable mixture is then prepared by mixing into the preblended mixture the remaining starch-based binder, water, and other desired admixtures, e.g., mold-releasing agents, inorganic filler rheology-modifying agents, plasticizers, coating materials, and dispersants, in the correct proportions to form an article which has the desired performance criteria. The moldable mixtures are heated between molds at an elevated temperature and pressure to produce form-stable articles having a desired shape and a selectively controlled foamed structural matrix. The articles may be manufactured to have properties substantially similar to articles presently made from conventional materials like paper, paperboard, polystyrene, plastic, or other organic-based materials and have especial utility in the mass-production of containers, particularly food and beverage containers.
