FIELD: technological processes.
SUBSTANCE: invention relates to low-density polyethylene for coating by extrusion. Polyethylene has density of 0.910–0.924 g/cm3, determined according to ISO 1183 at 23 °C, longitudinal hardening value at 150 °C and stretching rate of 1 s-1 4.2–10, Mw/Mn ratio 18–30, Mw values of 230,000–400,000 g/mol. Also disclosed are articles containing polyethylene.
EFFECT: obtaining low-density polyethylene with high value of longitudinal hardening and wide molecular-weight distribution without using peroxides with preservation of good organoleptic properties.
