FIELD: chemistry.
SUBSTANCE: polymer containing from 80.0 to 99.0 wt % of polymer links formed from ethylene and 1.0 to 20.0 wt % of polymer layers, formed from one or more C3-C20-α-olefin comonomers, is suitable for the production of films in the process of forming a tubular film when the degree of the bulge (BUR) of 3.0 to 8.0, and the ratio for the length of the neck (NHR) of 2.0 to 12.0. In addition, the ethylene-based polymer has a local maximum of the loss angle for the complex modulus, G*, equal to 2.50×104 up to 1.00×106Pa, and the local minimum of the loss angle with the complex modulus, G*, equal to 1.00×104 up to 3.00×104 Pa.
EFFECT: films have excellent shrinkage and tear characteristics.
