FIELD: manufacturing technology.
SUBSTANCE: invention relates to the field of polymeric materials for packaging and relates to sealing film of heat-sealable polymer. On the first side (15) of sealing film (10), surface structures (14), maximum thickness (h2) of sealing film (10) is at least 10 % greater than minimum thickness (h1) of sealing film (10), and maximum lateral distribution (b1, b2) of surface structures (14) is less than 500 mcm, and slip additive in amount that provides index S of less than 5,000 is added to sealing film (10).
EFFECT: invention provides sealing film with improved heat-sealing properties and sliding property.
