Abstract

L'invention est relative à un matériel pour enveloppements sous forme d'un objet de forme poreux dont une surface est entièrement recouverte d'une feuille plastique, caractérisé en ce que l'objet de forme poreux est formé de cellulose régénérée et comprend une poudre, des fibres et/ou des fibrides en matière plasique susceptible d'être soudée ou scellée, dans une proportion d'au moins 3 % en poids, et en ce qu'une feuille présentant une surface susceptible d'être soudée ou scellée est fixée sur cet objet de forme poreux, par soudure ou scellement Elle concerne également un procédé pour la fabrication de ce matériel.The invention relates to a material for wraps in the form of a porous shaped object whose surface is entirely covered with a plastic sheet, characterized in that the porous shaped object is formed of regenerated cellulose and comprises a powder , fibers and / or fibrids of plastic material capable of being welded or sealed, in an amount of at least 3% by weight, and in that a sheet having a surface capable of being welded or sealed is attached on this porous shaped object, by welding or sealing. It also relates to a process for the manufacture of this material.
