Abstract

L'invention concerne un sachet d'emballage (10) constitué d'un film d'emballage souple, contenant des produits, tels que des produits pharmaceutiques ou médicamenteux, des produits cosmétiques ou des compléments alimentaires et présentant une aide (18) à la déchirure permettant d'ouvrir le sachet (10) à la main. Le sachet (10) selon l'invention présente comme aide à l'ouverture une surface (23, 25) qui adhère bien et ne glisse pas dans au moins une zone de surface voisine de l'aide (18) à la déchirure. Cette mesure permet une ouverture aisée du sachet même pour des personnes ayant des difficultés au niveau des mains et des doigts, par exemple des personnes âgées souffrant d'arthrose, de rhumatisme, de goutte ou d'autres maladies limitant la mobilité et le fonctionnement des membres.
