LLDPE-based thermoshrinkable films

Polyolefin compositions and blown films obtained therefrom

Stretchable multilayer films in which at least one layer (A) thereof comprises a copolymer (I) of ethylene with one or more .alpha.-olefins CH.sub.2 .dbd.CHR, having a density of between 0.88 and 0.945 g/cm.sup.3, a melt index of from 0.1 to 10 g/10' and containing up to 20 mol % of .alpha.-olefin CH.sub.2 .dbd.CHR (LLDPE), and at least one layer (B) comprises a heterophasic polyolefin composition having:

Stretchable multilayer films

Stretchable multilayer films in which at least one layer comprises:

LLDPE-based stretchable multilayer films

Multi-layer heat-shrinkable films in which at least one layer (A) is based on a polyolefin composition comprising a propylene copolymer and having particular crystallinity characteristics, and at least one layer (B) comprises a linear compolymer of ethylene with one or more .alpha.-olefins (LLDPE). The films are characterized by an optimum balance of physicomechanical properties, processability and sealability at low temperatures.

Multilayer thermoshrinkable films

Polymeric compositions based on Linear Low Density Polyethylene (LLDPE) comprising: (A) from 75 to 95% by weight of an ethylene copolymer with an .alpha.-olefin CH.sub.2 =CHR, wherein R is an alkyl radical having from 1 to 10 carbon atoms, and (B) from 5 to 25% by weight of a copolymer of propylene with ethylene and an .alpha.-olefin CH.sub.2 =CHR.sup.I, wherein R.sup.I is an alkyl radical having from 2 to 10 carbon atoms. Copolymer (B) is characterised by a relatively high insolubility in xylene. The polymeric compositions of the invention are endowed with improved processability and improved mechanical properties with respect to the LLDPE of the conventional type.

Highly processable polymeric compositions based on LLDPE

Disclosed is a polymer composition of (A) a polyolefin composition consisting essentially of (i) a linear low density polyethylene and (ii) a copolymer of propylene with ethylene and/or a C.sub.4 -C.sub.8 .alpha.-olefin, where R is an alkyl radical having 2 to 10 carbon atoms and (B) a low density polyethylene.
