Abstract
The invention is directed to coextruded tapes, films, yarns and the likes of polylactic acid (PLA) and methods of preparation thereof. The present invention is directed to an extruded tape, film or yarn comprising a first phase, in particular a first layer, based on PLA and a second phase, in particular a second layer, also based on PLA, but having different sealing properties, wherein the peak melt temperature or seal initiation temperature of the second layer is lower than the peak melt temperature and/or the melt seal initiation temperature of the first layer, or wherein the Vicat softening point of the second layer is lower than the Vicat softening point of the first layer.
Claims16
A tape, film or yarn comprising a first layer and a second layer, both based on PLA, wherein said second layer is coextruded on said first layer, wherein the seal initiation temperature and/or peak melt temperature of said second layer is lower than the seal initiation temperature and/or the peak melt temperature of said first layer.
A tape, film or yarn comprising a first layer and a second layer, both based on PLA, wherein said second layer is coextruded on said first layer, wherein the Vicat softening point of said second layer is lower than the Vicat softening point of said first layer.
