As a molded article that has gas barrier properties even if a gas barrier layer is not provided and that also has molding stability and biodegradability, there is proposed a molded article containing an aliphatic polyester-based resin (A) and a polyvinyl alcohol-based resin (B) as main component resins, wherein the molded article has a resin phase-separated structure having a continuous phase including the aliphatic polyester-based resin (A) as a main component, and a ribbon-like dispersed phase including the polyvinyl alcohol-based resin (B) as a main component.

A recyclable, cold-sealing packaging having at least a first film and a cold-sealing compound and a print. The film is formed from a largely unmixed polyolefin, is stretched monoaxially in the machine direction and has at least two layers. At least one layer has an inorganic filler to create cavities in the layer.

Water-soluble unit dose article comprising a laundry or automatic dishwashing detergent and a method of making.

A multi-layer polymer film comprising at least one middle layer A, the polymeric constituents of which are soluble in aqueous solution, and at least one substantially water-impermeable covering layer B or C arranged above and/or below the at least one middle layer A, wherein the layers A, B and C independently of each other in each case comprise at least one thermoplastic polymer and at least one of the covering layers B and C comprises at least one polyhydroxyalkanoate. Processes for the production of the multi-layer polymer film according to the invention and its use for the production of molded parts, films or bags are furthermore presented and described.

The resin composition of the present invention comprises 40 to 98 parts by mass of a modified starch (A), 2 to 60 parts by mass of a polyvinyl alcohol (B) having a degree of saponification of 75.0 mol % or more, and optionally a clay (C), wherein the total content of the (A), (B) and (C) is 100 parts by mass, and the peak temperature of tan in measurement of dynamic viscoelasticity in a range of 20 C. to 150 C. is 128 C. or lower.

This disclosure describes hydrogel three-dimensional printing kits, methods of three-dimensional printing hydrogels, and hydrogel three-dimensional printing systems. In one example, a hydrogel three-dimensional printing kit can include a particulate build material and an aqueous agent. The particulate build material can include from about 90 wt % to 100 wt % of a mixture of a powdered polyhydroxylated swellable polymer dry blended with powdered water-soluble crosslinker that is reactive with hydroxyl groups of the polyhydroxylated swellable polymer to crosslink the polyhydroxylated swellable polymer. The aqueous agent can include water and an organic co-solvent, and the aqueous agent may not include the crosslinker.

The invention is directed to a method for producing an upgraded polymer product from recycled polyvinyl butyral, to a polymer product obtainable by said method, to a construction material comprising such polymer product, and to a use of an extruder vacuum pump. The method of the invention comprises feeding a polymer feed stream to an extruder, wherein said polymer feed stream comprises a recycled polyvinyl butyral; melting said polymer feed stream in the extruder to produce polymer melt and passing said polymer melt through one or more degassing zones connected to a vacuum pump; measuring the melt flow index of the polymer product,
wherein the vacuum pump is operated at a pressure that is controlled by the measured melt flow index of the polymer product.
