摘要： 1) Multilayer film comprising: an adhesive layer A consisting of a self-adhesive, thermo-fusible extrudable composition; a complexable thin layer B; and a thermosealable and breakable layer C of a linear copolymer C1 obtained by polycondensation of a composition of monomers comprising at least one diol (i), at least one compound (ii) selected from terephthalic acid or one of the diester derivatives thereof, and at least one compound (iii) selected from an aromatic or aliphatic carboxylic diacid or one of the diester or anhydride derivatives thereof; the quantities of monomers (i), (ii) and (iii) used in the polycondensation being such that the softening temperature of C1 is less than 190 °C. 2) Method for producing said multilayer film by co-extrusion blow moulding, at a temperature between 150 °C and 200 °C. 3) Reclosable package comprising a PET container and a lid consisting of said multilayer film, the thermosealable and breakable layer (C) of which is thermosealed on said container.
