    The invention relates to the manufacture of packaging films based on polyolefins, in particular to a composition for application to a polypropylene film.
    The purpose of the invention is to increase the strength of the weld.
    The strength of the welds is determined at low pressure. In this case, the strength of the welds is defined as the force required to separate the materials produced under certain conditions (0.35 N / cm, 0.5 s and at
    tables temperature) welded ggaa. Strength is also measured by Newtons (H); it refers to a 5 m wide sample. EXAMPLE 3. H1 linear statistical copolymer 96 wt.% Ethylene
