Abstract: Product made using a mass that includes natural polymers, wherein the product has at least a first product part connected by a hinge construction to a second product part, wherein the hinge construction has at least one flexible sheet element and at least one bridge portion made of the mass that includes natural polymers, wherein the hinge construction is designed such that, prior to a first time hinging, the at least one bridge portion forms a more rigid connection between the first and second product parts than the flexible sheet element and by hinging the bridge portion is severed, such that the first and second parts are substantially only connected by the at least one flexible sheet element.

Abstract: Product made using a mass comprising natural polymers, wherein the product comprises at least a first and a second product part, connected by a hinge construction, wherein the hinge construction comprises at least one flexible sheet element and one bridge portion made of said mass comprising natural polymers, wherein the hinge construction is designed such that, prior to a first time hinging, the at least one bridge portion forms a more rigid connection between the first and second product part than the flexible sheet element and by hinging said bridge portion is severed, such that the first and second part are substantially only connected by the or each flexible strip.

Abstract: A method for manufacturing sustainable products with a blown, foam structure, wherein a mass comprising at least natural polymers such as starch is passed under pressure into a mold cavity (4) or through a mold die, and the mass is heated in the mold in a manner such as to stabilize the foamed structure to form the product, wherein the method comprises prefoaming of the mass prior to injection in the mold. Preferably, the prefoamed mass is kept under pressure until insertion in the mold. The invention further relates to an apparatus to be used in said method.

Abstract: Method for coating a product having a wall formed by at least a portion having at least partly a cell structure, preferably at least partly an open cell structure, wherein a foil or foil laminate is pressure formed over at least a part of at least one side of said wall, said foil or at least one layer of said laminate forming a coating of said part of the wall.

Abstract: A method for manufacturing sustainable products with a blown, foam structure, wherein a mass comprising at least natural polymers such as starch is passed under pressure into a mould cavity (4) or through a mould die, and the mass is heated in the mould in a manner such as to stabilize the foamed structure to form the product, wherein the method comprises prefoaming of the mass prior to injection in the mould. Preferably, the prefoamed mass is kept under pressure until insertion in the mould. The invention further relates to an apparatus to be used in said method.

Abstract: An apparatus for injection molding products from a mass including at least natural mono or polymers, provided with at least one mold cavity (2) and a deaeration channel (10) at least partly surrounding the mold cavity (2), wherein, between the deaeration channel and the mold cavity an overflow (8) space is provided which, on the one side, is in communication with the deaeration channel and, on the other side, with the mold cavity (2).

Abstract: A holder for information carriers provided with an orientation surface and at least one engaging element integrated in the orientation surface for engaging the information carrier, wherein the holder is manufactured from a material produced on the basis of starch, such as Paperfoam®. A device provided with such a holder and at least one leaf part, while the at least one leaf part and the at least one holder are attached to each other.

Abstract: A method for manufacturing products with a coating, wherein from at least one mass comprising at least natural polymers, a base product is manufactured, while to at least one part of the product, a coating is applied, a coating being used having a surface tension which is approximately equal to or preferably lower than the surface tension of a portion of the mass, at least of the or each relevant part of the base product to which the coating is applied.

Abstract: A method for manufacturing products, wherein a mass, comprising at least natural polymers such as starch, is brought into or through a mold and the mass in the mold is heated, such that this involves at least cross-linkage of the natural polymers, while of at least one first part of the product, the material composition is influenced such that the material properties of the relevant first part deviate from the material properties of parts adjoining said part.

Abstract: The invention relates to a method for manufacturing molded bodies having a blown, foamy structure, wherein a mass (S) comprising a suspension of at least starch, starch derivatives or mixtures thereof in water, is pressurized in or through a mold (23) and the mass (S) heated in the mold (23) in a manner such as to give rise to at least cross-linking of the starch, the starch derivatives or the mixture thereof wherein the mass (S) in the mold (23) is brought at least to the baking temperature, wherein the suspension is at least partially prepared from vegetable material which has not been subjected to an artificial drying step and which, calculated on the dry substance, contains at least 50 wt. % of starch, said vegetable material at least being ground to particles of a suspendable size. The invention further relates to the use of ground vegetable material, which vegetable material has not been subjected to an artificial drying step and, calculated on the dry substance, contains at least 50 wt.

Abstract: A method for manufacturing products with a blown foamy structure, starting from a mass comprising at least natural polymers such as starch and fibers, in particular natural fibers, wherein the mass (M, S) is passed under pressure into or through a mould (23, 63) and the mass (M, S) is heated in the mould (23, 63) in a manner such as to give rise to gelatinization and cross-linking of the natural polymers, with the fibers extending through the product, while the mass prior to the introduction into the mould has temperature which is below the gelatinization temperature and in the mould is brought at least to the baking temperature.

Abstract: A method for manufacturing biodegradable products with a blown foamy structure, wherein a mass comprising at least natural polymers such as starch is passed under pressure into or through a mould and the mass is heated in the mould in a manner such as to give rise to at least cross-linking of natural polymers, while the mass prior to the introduction into the mould has a temperature which is below the gelatinization temperature and in the mould is brought at least to the baking temperature.
