  • Method for the production of biologically-degradable packagings made from biaxially-drawn films
    Patent number: 7128969
    Abstract: 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.

    Assignee: Trespaphan GmbH
    Inventors: Detlef Busch, Marlies Rosenbaum, Manfred Rosenbaum
  • Method for producing biodegradable packing from biaxially drawn film
    Publication number: 20050098928
    Abstract: The invention relates to a method for producing a plastically moulded, biaxially drawn PLA film. According to said method, a biaxially drawn PLA film is heated to a high temperature and is plastically moulded by a pneumatic or mechanical force, or by a combination of pneumatic and mechanical force. The invention also relates to packaging produced from biaxially drawn, plastically moulded PLA film of this type and to a method for producing said packaging and the use thereof.
