    摘要: A process for filling and self-sealing containers with molten materials is provided. The process comprises filling a container with a molten material and covering the surface of the molten material which is still at elevated temperature after filling with an insert consisting of a plastic film and a plastic disk. The plastic film faces the molten material and is larger than the plastic disk. The diameter of the plastic disk is slightly smaller than the internal diameter of said container.

    摘要: The invention relates to thermoplastic compositions that contain reactive isocyanate groups and that are suitable for use as desiccants for packaging moisture-sensitive goods, especially for polyurethane hotmelt adhesives that are cross-linked upon exposure to moisture. The compositions are formed by the reaction of hydroxy- or amino-containing polyols, including sugars, with an excess of polyisocyanates, and admixing the resulting product with polyurethane catalysts.
