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 1):
A multilayer film comprising:\n an adhesive layer A having a thickness ranging from 7 to 50 \u03bcm and consisting of an extrudable hot-melt self-adhesive composition a which has a melt flow index (or MFI), measured for a temperature of 190\u00b0 C. and a total weight of 2.16 kg, ranging from 0.01 to 200 g/10 minutes and which comprises, on the basis of the total weight of said composition a:\n from 40% to 70% by weight of a composition al of styrene block copolymers comprising at least one elastomer block, said composition al consisting, on the basis of its total weight:\n of 30% to 90% by weight of at least one diblock copolymer chosen from the group comprising SI, SBI, SIB, SB, SEB and SEP, and \n of 10% to 70% by weight of at least one triblock copolymer chosen from the group comprising SIS, SIBS, SBS, SEBS and SEPS; \n the total content of styrene units of said composition al ranging from 10% to 40% by weight on the basis of the total weight of al; and \n \n from 30% to 60% by weight of one or more tackifying resins a2 having a softening temperature of between 5 and 140\u00b0 C.; \n a complexable thin layer B consisting of a thermoplastic b; and a heat-sealable and cleavable layer C; the layers B and C being linked to one another by the layer A; and said film being characterized in that the layer C consists of a composition c comprising, on the basis of the total weight of c, a content by weight of at least 95% of at least one linear copolyester C1 obtained by polycondensation of a composition m of monomers comprising:\n at least one diol (i), \n at least one compound (ii) chosen from terephthalic acid or a diester derivative thereof, optionally substituted with an alkyl radical, and \n at least one compound (iii) chosen from an aromatic or aliphatic dicarboxylic acid or a diester or anhydride derivative thereof; \n the amounts of the monomers (i), (ii) and (iii) used in the polycondensation being such that the softening temperature of C1 is below 190\u00b0 C.
