Abstract
(EN)
The purpose of the present invention is to provide: release paper which includes a sealing layer comprising a biomass-derived resin and/or a biodegradable resin and which, despite this, is equal in releasability to conventional release papers including a layer of a fossil-fuel-derived polyolefin; and a pressure-sensitive adhesive sheet, a label base paper, and a label all including the release paper. The present invention provides release paper 10 which comprises: a paper base 11; one or two sealing layers 12 disposed on one or both surfaces of the paper base 11 and each comprising a biomass-derived resin and/or a biodegradable resin; and a release layer 13 disposed on at least one of the sealing layers 12.

Le but de la présente invention est de fournir : un papier anti-adhésif qui comprend une couche d'étanchéité comprenant une résine dérivée de biomasse et/ou une résine biodégradable et qui, en dépit de cela, est égale en termes de capacité de libération à des papiers anti-adhésifs classiques comprenant une couche d'une polyoléfine dérivée de combustible fossile ; et une feuille adhésive sensible à la pression, un papier de base d'étiquette et une étiquette comprenant tous le papier anti-adhésif. À cet effet, la présente invention concerne un papier anti-adhésif (10) qui comprend : une base de papier (11) ; une ou deux couches d'étanchéité (12) disposées sur une surface ou sur les deux surfaces de la base de papier (11) et comprenant chacune une résine dérivée de biomasse et/ou une résine biodégradable ; et une couche anti-adhésive (13) disposée sur au moins l'une des couches d'étanchéité (12).
