Patent Name Toughness-Elastic Material Patent Applicant Innograd AG Principal Applicant Address Zruger, Switzerland Inventor Rolf Mueller; Application for Patent of Frederico Inniebner (patent) No. 200480000502.9 Date of Application 2004.03. 26 Certification Date Approval Notice No. 1697840 Auditing Notice Day 2005.11.16 Manual CD-ROM D0546 Main Classification Code C08B31/00 Classification Code C08B31/00; C08L3/02 Classification Original Application No. Priority Item 2003.3.28 DE 10314418.8; 2003.6.18 DE 10 32 787 0.2 Abstract The present invention relates to a starch-based tough-elastic material which on the one hand has a high impact toughness at low humidity and on the other hand also has a high elastic modulus at high humidity and within a wide humidity range. It also has high stretchability, and also because its performance profile is suitable for use as a molding element, such as foils, films, fibers, injection molded articles, in particular edible films, for packaging of active ingredients, chemicals, fragrances, and spices. Use, as well as high quality replacements for gelatin in soft and hard capsules. A transparent tough-elastic material can be obtained and adjusted to achieve its solubility or swelling or decomposition in water, or still intact. Sovereignty items 1. A starch-based toughness-elastic material characterized by said ductile-elastic material with a relative humidity of RH, RFz transitioning from brittle to ductile, at room temperature, at <33% relative humidity (RH). The lower RFz is preferably <26, more preferably <20, most preferably <15, and at 85%, the elastic modulus E is expressed in MPa as >0.1. Preferably> 0.5, more preferably> 1.0, most preferably> 3, generally <50.
