Double bubble process for manufacturing orientated cellulose films

This application relates to producing biaxially stretched tubular cellulose films for the food industry. In particular, the biaxial stretching is obtained by using rollers to stretch the casings longitudinally and to use increased air pressure inside the films to radially stretch the casings. The ob...

Beschreibung
Zusammenfassung:	This application relates to producing biaxially stretched tubular cellulose films for the food industry. In particular, the biaxial stretching is obtained by using rollers to stretch the casings longitudinally and to use increased air pressure inside the films to radially stretch the casings. The obtained product may also be cut to provide longitudinal strips for the production of smaller tubular films.
