Title
(EN) A MOULDABLE FIBROUS SHEET AND A PRODUCTION METHOD THEREOF
(FR) FEUILLE FIBREUSE MOULABLE ET SON PROCÉDÉ DE PRODUCTION
Abstract
(EN)
The present invention relates to a web of fibrous cellulosic material derived from wood pulp, said web being suitable for three-dimensional moulding to form a packaging product, wherein the web comprises >40wt% of soft wood chemical pulp and at least one strength enhancement agent, wherein the web has a grammage less than 400g/m2, and wherein the cellulose fibers of said soft wood chemical pulp comprise a fiber curl of >9%.
(FR)
La présente invention concerne une bande constituée d’un matériau cellulosique fibreux dérivé de pâte de bois, ladite bande étant appropriée pour un moulage tridimensionnel pour former un produit d’emballage, la bande comprenant plus de 40 % en poids de pâte chimique de bois tendre et au moins un agent de renforcement de résistance, la bande ayant un grammage inférieur à 400 g/m2, et les fibres de cellulose de ladite pulpe chimique de bois tendre comprenant une boucle de fibre de plus de 9 %.
