Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
72 words
A shrink film made by stretching in two planar directions a homogeneous composition comprising: (1) about 7-80% Very-Low-Density polyethylene, as defined in the specification, having a melt index of at least 2 g/10 min.; (2) about 93-20% of a linear copolymer of ethylene with one or more α -olefin, having only one crystallite melting region; and (3) 0-15% in weight of vinyl acetate or acrylate in a vinyl acetate or acrylate-based copolymer.
Claim 2
Dependent Claim
38 words
A film according to claim 1, wherein the Very-Low-Density Polyethylene is a copolymer of ethylene with an α-olefin, having a density of less than about 0.90 g/cm³ and a melt index (1900°C/2.16 kg) of at least 5g/10 min.
Claim 3
Dependent Claim
11 words
A film according to claim 2, wherein the α-olefin is butene.
Claim 4
Dependent Claim
27 words
A film according to any one of claims 1 to 3, wherein the linear copolymer of ethylene with the α-olefin is a copolymer of ethylene with 1-octene.
Claim 5
Dependent Claim
17 words
A film according to claim 4, wherein the copolymer of ethylene with 1-octene is a DOWLEX polymer.
Claim 6
Dependent Claim
26 words
A self adhesive film, according to any one of claims 1 to 5, comprising about 0% to about 7% by weight of vinyl acetate or acrylate.
Claim 7
Dependent Claim
22 words
A film according to any one of claims 1 to 6, wherein the vinyl acetate or acrylate-based copolymer is an ethylene copolymer.
Claim 8
Dependent Claim
20 words
A film according to claim 1, which is stretched in two linear directions up to 8 times in each direction.
Claim 9
Dependent Claim
22 words
A film according to any one of claims 1 to 8, essentially as described and illustrated, with particular reference to the examples.
Claim 10
Dependent Claim
22 words
A label which is particularly suitable for labelling deformable articles, comprising a film according to any one of claims 1 to 9.
Claim 11
Independent Claim
39 words
A method of labelling an article, comprising providing a label made of a film according to any one of claims 1 to 9, and causing this label to adhere to the article to be labelled by a shrink-and-cling action.
