Title
(EN) COMPOSTABLE LAMINATE STRUCTURE
(FR) STRUCTURE STRATIFIÉE COMPOSTABLE
Abstract
(EN) A compostable laminate for food wrap and method for making same. The wrap can include a first layer of paper material, a second layer of paper material, and a series of coatings between the paper materials. The coatings include a first flood coating having water and/or barrier properties, a second flood coating having water and/or oil barrier properties, and a third coating that only partially covers the second flood coating. None of the first, second and third coatings comprise a thermoplastic or polyolefin, and are made substantially from one or more biodegradable and/or compostable materials.
(FR) L’invention concerne un stratifié compostable pour film alimentaire et un procédé pour sa fabrication. Le film peut comprendre une première couche d’un matériau de type papier, une seconde couche d’un matériau de type papier et une série de revêtements entre les matériaux de type papier. Les revêtements comprennent un premier revêtement en pleine surface ayant des propriétés de barrière à l’eau et/ou à l’huile, un deuxième revêtement en pleine surface ayant des propriétés de barrière à l’eau et/ou à l’huile et un troisième revêtement qui ne recouvre que partiellement le deuxième revêtement en pleine surface. Aucun du premier, du deuxième et du troisième revêtement ne comprend un thermoplastique ou une polyoléfine, et ils sont constitués essentiellement d’un ou plusieurs matériaux biodégradables et/ou compostables.
