Title (EN) PACKAGING MATERIALS
(FR) MATÉRIAUX D'EMBALLAGE
Abstract: front page image
(EN)A biodegradable packaging material and methods of manufacturing the same are provided in which a biodegradable substrate and a biodegradable polymer film are laminated together without the use of an adhesive interlayer. The film may be made of material that is soluble in water or which swells when exposed to moisture and is biodegradable. Off-line methods employing preformed substrates and films are disclosed as well as on-line methods in which the film is formed on a liner prior to the laminating process or is extruded onto the substrate.
(FR)L'invention concerne un matériau d'emballage biodégradable, et des procédés permettant de produire ce matériau, consistant à assembler par stratification un substrat biodégradable et une pellicule polymère biodégradable sans utiliser de couche adhésive intermédiaire. La pellicule peut être produite dans un matériau soluble dans l'eau ou gonflant lorsqu'il est exposé à l'humidité, et qui est biodégradable. L'invention concerne également des procédés hors ligne comprenant l'utilisation de substrats et de pellicules préformés, ainsi que des procédés hors ligne consistant à former la pellicule sur une feuille couverture avant l'opération de stratification, ou à extruder la pellicule sur le substrat.
