Patent

CA 2742590

The invention encompasses blends of polymers including, for example, polylactic acid and polyethylene terephthalate and articles manufactured therefrom. In certain embodiments, the invention encompasses blends of polymers including, for example, polylactic acid and polyethylene terephthalate that are useful in packaging and have improved physical properties, such as flexibility, elongation and/ or deadfold. In addition, the polymer blends of the invention may be suitable for a number of applications, such as in the manufacture of disposable bottles, wraps, bags and other packaging materials or as coating materials.

L'invention porte sur des mélanges de polymères comprenant, par exemple, du poly(acide lactique) et du poly(téréphtalate d'éthylène) et sur des articles fabriqués à partir de ceux-ci. Dans certains modes de réalisation, l'invention porte sur des mélanges de polymères comprenant, par exemple, du poly(acide lactique) et du poly(téréphtalate d'éthylène) qui sont utiles dans l'emballage et qui ont des propriétés physiques améliorées, telles que la souplesse, l'allongement et/ou la permanence de la marque du pli. De plus, les mélanges de polymères de l'invention peuvent être appropriés pour un certain nombre d'applications, telles que dans la fabrication de bouteilles, emballages, sacs jetables et autres matières d'emballage ou comme matières de revêtement.
