Abstract:
A multilayer film: an adhesive layer A: an extrudable hot-melt self-adhesive composition; a complexable thin layer B; and a heat-sealable and cleavable layer C of a linear copolyester C1 obtained by polycondensation of a composition of monomers:          at least one diol (i), at least one compound (ii) chosen from terephthalic acid or a diester derivative and at least one compound (iii) chosen from an aromatic or aliphatic dicarboxylic acid or a diester or anhydride derivative;   the amounts of the monomers (i), (ii) and (iii) used in the polycondensation such that the softening temperature of C1 is below 190° C. A process for producing the multilayer film by co-extrusion blow-molding. A resealable packaging comprising a PET-based receptacle and a seal of said multilayer film, the heat-sealable and cleavable layer (C) of which is heat-sealed on the receptacle.

Claim (Index 13):
The production process as claimed in  claim 11 , characterized in that it comprises:\n (i) the introduction, into separate extruders, of constituent compositions and materials of the layers A, B, C, and where appropriate D and E, in the form of granules having a size of between 1 and 10 mm, then (ii) the conversion by heating of said granules to the viscous liquid state, then (iii) the passing of the corresponding streams through an extrusion head comprising a set of coplanar and concentric annular dies, each brought to a temperature below 200\u00b0 C., so as to form a tubular bubble comprising several layers, in which the order of the layers corresponds to that desired for the final film, then (iv) the radial expansion and the drawing of the bubble, then (v) the cooling of said bubble.
