METHOD FOR THE PRODUCTION OF BIOLOGICALLY-DEGRADABLE PACKAGINGS MADE FROM BIAXIALLY-DRAWN FILMS

摘要

The invention relates to a method for the plastic shaping of a biaxially-drawn film, comprising at least one base layer, containing at least one polymer (I), made from at least one hydroxycarboxylic acid and >/= 0.2 wt. %, based on the weight of the layer, of a thermoplastic polymer (II), different from polymer (I). Said film is plastically moulded by application of pneumatic and/or mechanical forces.
