Multilayer films

A multilayer stretch film comprising from 3 to 15 layers, said stretch film comprising:

• 1) a first skin layer comprising an ethylene interpolymer product having a melt index of from 2.5 to 4.5 dg/minute, wherein melt index is measured according to ASTM D 1238 (2.16 kg load and 190° C.) and a density of from 0.905 to 0.914 g/cc, wherein density is measured according to ASTM D792;
• wherein said ethylene interpolymer product comprises:
• (I) a first ethylene interpolymer;
• (II) a second ethylene interpolymer, and;
• (III) optionally a third ethylene interpolymer;
• wherein said first ethylene interpolymer is produced using a single site catalyst formulation comprising a component (i) defined by the formula:
• (LA)aM(Pl)b(Q)n
• wherein LA is selected from the group consisting of unsubstituted cyclopentadienyl, substituted cyclopentadienyl, unsubstituted indenyl, substituted indenyl, unsubstituted fluorenyl and substituted fluorenyl;
• M is a metal selected from the group consisting of titanium, hafnium, and zirconium;
• Pl is a phosphinimine ligand;
• Q is independently selected from the group consisting of a hydrogen atom, a halogen atom, a C1-10 hydrocarbyl radical, a C1-10 alkoxy radical and a C5-10 aryl oxide radical;
• wherein each of said hydrocarbyl, alkoxy, and aryl oxide radicals may be unsubstituted or further substituted by a halogen atom, a C1-18 alkyl radical, a C1-8 alkoxy radical, a C6-10 aryl or aryloxy radical, an amido radical which is unsubstituted or substituted by up to two C1-8 alkyl radicals or a phosphido radical which is unsubstituted or substituted by up to two C1-8 alkyl radicals;
• wherein a is 1;
• b is 1;
• n is 1 or 2;
• and (a+b+n) is equivalent to the valence of the metal M, and;
• wherein said second ethylene interpolymer is produced using a first in-line Ziegler-Natta catalyst formulation;
• wherein said third ethylene interpolymer is produced using said first in-line Ziegler-Natta catalyst formulation or a second in-line Ziegler-Natta catalyst formulation, and;
• wherein said ethylene interpolymer product has a Dilution Index, Yd, greater than 0;
• and
• 2) at least one core layer comprising a linear ethylene copolymer having a density of from 0.905 to 0.935 g/cc and a melt index of from 2 to 6 dg/minute;
• wherein said multilayer stretch film has a total thickness of from 0.4 to 2.5 mils;
• haze of less than 5% and gloss of greater than 70%.
