COEXTRUDED FILM SUITABLE FOR THERMAL LAMINATION ON PRINTED PLASTIC BACKING, APTED TO ALLOW THE MANUFACTURE, WITH NO GLUE, OF A MULTILAYER FLEXIBLE LAMINATED FILM HAVING AN INTERNAL COATING

摘要

A description is given of a flexible thermally laminated multilayer film ready for use (10), particularly suitable for being used as closure film (top) of food container trays, said multilayer film being formed by a coextruded film (4) bonded to a plastic backing film (3), preferably a biaxially oriented film having preferably a print (5), characterised in that said coextruded film (1) has a side (1) with sticky or adhesive properties such as to enable it to be thermally laminated on said plastic film without the use of glues, said bonding being obtained through the effect of the heat and of the pressure.
