| abstract |
The invention concerns a packaging film comprising a base film partly coated on one of its surfaces, called internal surface, with a self-sealing composition, said film capable of being wound without anti-adhesive treatment of the other surface, called external surface. The invention is characterised in that said self-sealing composition is free of allergenic proteins as those contained in natural rubber and comprises a polychloroprene, optionally modified, in particular at least 30 % by dry weight and preferably less than 10 %. The invention also concerns the package itself, in particular a package for sterilising packaging of products requiring sterilisation. The invention further concerns the method for making said sheet. |
