摘要： In one aspect, the invention provides a substantially exfoliated nanocomposite material including starch and hydrophobically modified layered silicate clay. In another aspect, the invention provides packaging made from material including the substantially exfoliated nanocomposite material described above. The nanocomposite material has improved mechanical and rheological properties and reduced sensitivity to moisture in that the rates of moisture update and/or loss are reduced. In another aspect, the invention provides a process for preparing the substantially exfoliated nanocomposite material described above, including a step of mixing the starch in the form of an aqueous gel with the hydrophobic clay in a melt mixing device. In a further aspect, the invention provides a process for preparing the substantially exfoliated nanocomposite material, including the steps of mixing the starch with the hydrophobic clay to form a masterbatch (hereinafter “the masterbatch process”) and mixing the masterbatch with further starch.

摘要： A blister package consists of a backing sheet (16) of cardboard, paper or plastic adhered to a blister (17) in which at least one or both of the backing sheet and the blister is made from a transparent water soluble thermoformable polymer composition. A tooth brush, cleaning utensil or garden utensil enclosed in the water soluble packaging material can be opened by placing it under running water. The packaging material is a starch or modified starch based polymer by direct contact with water, and that biodegrades in waste water. The preferred starch is a high amylose maize starch. The starch can also be derived from wheat, potato, rice, oats, arrowroot and pea sources. The backing sheet is adhered to water and applying the backing sheet with the use of a press plate (24).

摘要： 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.
