Embodiments of the present disclosure are directed to laminates comprising a uniaxially oriented first multilayer film comprising ethylene-based polymer, wherein the uniaxially oriented first multilayer film has a ratio of percent elongation at break in the cross direction to percent elongation at break in the machine direction of at least 2 to 1; a biaxially oriented second multilayer film adhered to the uniaxially oriented first multilayer film and comprising an ethylene-based polymer, wherein the biaxially oriented second multilayer film has a ratio of percent elongation at break in the machine direction to percent elongation at break in the cross direction of at least 2 to 1; and a third film adhered to the biaxially oriented second multilayer film such that the biaxially oriented second multilayer film is disposed between the uniaxially oriented first multilayer film and the third film, wherein the third film comprises an ethylene-based polymer.

The present invention concerns a film (), which contains at least one inner layer () and two outer layers () enclosing at least one inner layer () where the, at least one, inner layer () contains a polymer A in a quantity from 70 to 100 wt. %, preferably 80 to 99 wt. % and especially preferably from 90 to 99 wt. %, relative to the total weight of the inner layer (), which is characterized by special interesting properties, where the outer layers () contain a mixture of polymer A and a polymer B, where polymer B is selected from the group consisting of low-density polyethylenes, said film () having a thickness from 30 to 70 &#x3bc;m, preferably 35 to 60 &#x3bc;m and especially 40 to 55 and an elastic restoring capacity of more than 95% at an elongation of 55%. The present invention also concerns a process for the production of a film, the use of the wealth. As a stretch-sleeve up film and articles provided with the oil of the invention, such as packaging. The present disclosure is directed to a stretch-sleeve film and articles including the stretch-sleeve film. The stretch-sleeve film includes at least three layers including two skin layers and a core layer. The core layer includes at least 75 wt % of an ethylene/a-olefin copolymer (A) characterized by (i) a density from 0.890 g/cc to 0.920 g/cc; (ii) a Mw/Mn from 2.0 to 4.0; (iii) a ZSVR less than 6.0; and (iv) a CDC from 85 to 150. At least one skin layer includes a polymeric material selected from the ethylene/a-olefin copolymer (A), a low density polyethylene, a medium density polyethylene, and combinations thereof. The stretch-sleeve film has an elastic recovery at 55% stretch of at least 95%.
