Abstract

L'invention concerne un matériau de base et un procédé permettant d'emballer hermétiquement des déchets fumants et malodorants pour stocker des couches-culottes usées, des excréments d'animaux de compagnie, des détritus, ainsi que d'autres déchets fumants et malodorants, pour une période donnée, jusqu'à ce que ces déchets soient mis au rebut, sans qu'une odeur incommodante puisse régner. Le matériau de base comprend un matériau de base d'emballage (10) ainsi qu'une couche adhésive ou collante (11) qui est formée sur le matériau de base d'emballage (10). Le matériau de base d'emballage (10) et la couche adhésive (11) permettent de faire barrière aux gaz, et le déchet fumant et malodorant (2) est entouré par le matériau de base d'emballage (10) et emballé de manière hermétique par la couche adhésive (11). Pour stocker le déchet fumant et malodorant, par exemple une couche-culotte usée, jusqu'à une date de ramassage d'ordures, l'on emballe ce déchet au moyen du matériau de base d'emballage, et cet emballage est fermé hermétiquement par la couche adhésive qui est formée sur le matériau de base d'emballage. Ainsi, le matériau de base peut être formé de manière à constituer une barrière aux gaz qui ne permet pas de fuite d'odeur, dans la mesure où le déchet fumant et malodorant est entouré d'un emballage hermétique.
