  • Patent number: 6794540
    Abstract: A process for the preparation of sorbic acid by thermal cleavage of the polyester prepared from crotonaldehyde and ketene, in the presence of a solvent and of an amine as catalyst with simultaneous distillation out of the sorbic acid formed and of the solvent through a rectification column with reflux, wherein only the solvent rather than the distillate is used as reflux, leads to high yields of sorbic acid and to a reduced consumption of amine catalyst.

  • Patent number: 6749933
    Abstract: The invention relates to a packaging material made of a multilayer oriented polyolefin film, which comprises a base layer and at least one first outer layer, whereby the first outer layer is placed in contact with itself or in contact with the opposing surface of the film or in contact with the surface of another film. This first outer layer contains an additive which absorbs light within the wavelength range of a laser such that when the film is locally irradiated by the laser, the area of irradiation experiences an increase in temperature that causes the polyolefin of the first outer layer to soften or melt in the irradiated area and to bond to another layer when cooled.
