Provided is a resin composition comprising a starch and a polyvinyl alcohol, which is excellent in the breaking strength and breaking elongation at a low temperature, and at the same time, has the good gas barrier property. The resin composition comprises modified starch and polyvinyl alcohol, and where in a cross section photograph by a transmission electron microscope, a cross-sectional area of each of particles of the polyvinyl alcohol dispersed is calculated, and a cross-sectional shape of each of the particles of the polyvinyl alcohol is postulated to be circular based on the cross-sectional area, the particles of the polyvinyl alcohol have a conversion particle diameter of 50 to 300 nm, and the conversion particle diameter has a dispersity of 3.0 or less.

There is provided a multilayer film comprising a starch layer and at least one other layer. The multilayer film has excellent barrier properties. The starch layer comprises a modified starch having a degree of substitution less than 1.5. Suitable other layers include polyolefins. The multilayer film finds use in packaging, particularly in packaging foodstuffs.

The present document discloses a method of determining thickness of a wet film, in particular of microfibrillated cellulose. The method comprises conveying said film (20) in a wet state on a conveyor (10) having a conveyor width, the wet film having a film width which is less than the conveyor width, providing a laser projection (1511) across a film edge, acquiring a series of images, each depicting an area of the conveyor, wherein the laser projection, a portion of the film and a portion of an exposed conveyor surface are visible, and using at least some of said images to determine at least one of a film thickness and a film thickness distribution across the film width. The document also discloses a method of forming a film, in particular a microfibrillated cellulose film, and a device for producing such film.

An apparatus for applying a cellulose-based annular body to a perimeter flange of a container includes a supporting unit and an operating unit. The supporting unit has a seat to receive a body of the container and is surrounded by an annular portion on which the annular body and the flange rest, such that the annular body is interposed between the annular portion and the flange. A heating device heat the annular body. The supporting unit includes an annular recess, surrounding the annular portion, to at least partly house an annular end bead of the flange. The apparatus includes a forming device, movable along a respective axis of movement between a far position and an engaging position. In the engaging position, the forming device engages and deforms the annular bead pushing said annular bead into the annular recess.

The present disclosure relates to a solid hair cosmetic composition comprising—based on the total weight of the cosmetic composition—0.1 to 40.0% by weight of at least one polysaccharide, at least one polysaccharide being starch from corn, rice, potato or tapioca; modified starch; hydroxypropyl starch phosphate or a dextrin, and optionally: 10.0 to 60.0% by weight of at least one polyhydric alcohol, 0.1 to 15.0% by weight of at least one cationic surfactant, and 0.1 to 15.0% by weight of at least one saturated or unsaturated, branched or unbranched C.sub.8-C.sub.30 alcohol and/or a saturated or unsaturated, branched or unbranched C.sub.8-C.sub.30 carboxylic acid and/or a salt of a saturated or unsaturated, branched or unbranched C.sub.8-C.sub.30 carboxylic acid, as well as production and application methods and uses thereof.

An example method of forming a biodegradable component includes extruding a mixture of biodegradable material and water through a die. The method further includes dividing the extruded mixture to form a plurality of biodegradable pellets. The method further includes forming the plurality of biodegradable pellets into a component. The water acts as a binding agent to bind the plurality of biodegradable pellets to one another.

The present invention relates to two-dimensional and three-dimensional shaped parts and composite materials made of popcorn and synthetic and/or natural binding agents which are cured in automatic moulding machines or similar pressing installations by means of radio wave technology or microwaves. By means of these technologies, light-weight, two-dimensional and three-dimensional shaped parts and composite materials can be produced for packaging, as interior and exterior parts (for example in automobile and mobile-home construction), shock absorbers, space-dividing elements, furniture, consumer goods, for the building trade of for heat insulation.

A method for producing a thermoplastic resin composition, including: melt-kneading a mixture containing a polyester resin (A), a starch material (B), and water; and dewatering the melt-kneaded mixture to reduce a water content to 5% by weight or less. The mixture contains 25 to 55 parts by weight of the water per 100 parts by weight of a solid content of the starch material (B). A film containing a thermoplastic resin composition containing a biodegradable polyester resin (A) and a starch material (B), wherein the starch material (B) has a number-average particle diameter of 3 μm or less.

The invention relates to a method for producing a biodegradable thermoplastic starch-based article intended to come into contact with foodstuffs. In this method, the semi-crystalline starch granules are transformed into a homogeneous and almost amorphous material, called thermoplastic starch, by the addition of plasticizers at high temperatures and under shear. Thermoplastic starch is modified with organic acid during melt processing to prevent the retrogradation of starch. Moreover, cellulose derivatives are used as the reinforcement filler of thermoplastic starch. The article is produced using hot-pressing and then coating by immersion in a waterproofing solution.
