Abstract:
The present invention relates to the use of a at least a part of a polymer layer comprising a composition (Co), the composition comprising a low density polyethylene (LDPE) produced in a tubular reactor which composition is free of additives as a thermoplastic surface of an extrusion coated structure comprising the polymer layer and a first substrate for preparing heat-sealed articles by heat-sealing of said thermoplastic surface with a second substrate; and The use of a at least a part of a polymer layer comprising a composition (Co), the composition comprising a low density polyethylene (LDPE) having —a melt flow rate (MFR) according to ISO 1133 (190° C., 2.16 kg) higher than 3.0 g/10 min; —a molecular weight distribution Mw/Mn which is greater than 10; and —a vinylidene content which is at least 15/100k C; which composition is free of additives as a thermoplastic surface of an extrusion coated structure comprising the polymer layer and a first substrate for preparing heat-sealed articles by heat-sealing of said thermoplastic surface with a second substrate.
