Selluloosahydraattiin pohjautuva tasomainen tai letkun muotoinen kalvo

摘要

The film containing an optionally fibre-reinforced support material based on cellulose hydrate is preferably employed as a tubular synthetic sausage casing (sausage skin). Its support material essentially comprises a mixture of cellulose hydrate and alginic acid and/or alginate. The alginate is in particular the ammonium, alkali metal or alkaline earth metal salt of alginic acid. …A process for the production of the film by the viscose process is also described in which a mixture of alkaline viscose solution and a soluble salt of alginic acid is coagulated by means of an acidic precipitation liquid.
