CA 2629802

The aim of the invention is to provide shaped bodies based on gelatin which have a high mechanical strength and are sufficiently flexible. For this purpose, the shaped bodies are produced based on a cross-linked, gelatinous material. The invention is characterized in that the shaped body is drawn in such a manner that at least part of the gelatin molecules is oriented in a preferred direction and the material comprises a softener.

Selon l'invention, grâce à l'amélioration des taux d'étirage, des cylindres creux présentant une diamètre interne encore plus petit peuvent être produits, cela pouvant être très avantageux pour d'autres utilisations. Lors de l'utilisation du procédé de l'invention, il est possible de produire des petits tuyaux extrêmement fins et présentant un diamètre de l'ordre de 150 µm. Une telle valeur ne peut pas être obtenue sans étirage du petit tuyau.
