The present disclosure provides a multilayer film containing at least three layers, including (A) a core layer containing a high density polyethylene (HDPE) having a density from 0.940 g/cc to 0.980 g/cc; and (B) skin layers on opposite sides of the core layer. Each skin layer includes (i) a propylene/ethylene copolymer with from greater than 0 wt % to 5 wt % units derived from ethylene comonomer; (ii) from 3,000 to 3,500 ppm of a slip agent; and (iii) from 4,000 to 10,000 ppm of an antiblock agent.

Multilayer films containing a slip agent

Disclosed herein is a film comprising a layer that comprises a polyethylene composition comprising the reaction product of ethylene and optionally one or more alpha-olefin comonomers, wherein said polyethylene composition is characterized by the following properties: a melt index, I, measured according to ASTM D1238 (2.16 kg, 190 C), of from 0.5 to 10 g/10 min; a density (measured according to ASTM D792) of less than 0.935 g/cm; a melt flow ratio, I/I, wherein Iis measured according to ASTM D1238 (10 kg, 190 C) of from 6.0 to 7.5; a molecular weight distribution (Mw/Mn) of from 2.8 to 3.9; and a vinyl unsaturation of greater than 0.12 vinyls per one thousand carbon atoms, and a low density polyethylene.

Films having desirable mechanical properties and articles made therefrom

Embodiments relate to multilayer structures, multilayer films, and packages formed therefrom. As an example, a multilayer structure can include a multilayer structure comprising a polyolefin sealant layer, a coupling layer on the polyolefin sealant layer, where the coupling layer includes a polyolefin and a maleic anhydride grafted (MAH) polymer, where the total amount of MAH polymer is from 15 weight percent to 50 weight percent of a total weight percent of the coupling layer, where the polyolefin is selected from the group consisting of a high pressure low density polyethylene, a high density polyethylene, an ethylene acrylic acid copolymer, an ethylene(meth)acrylic acid copolymer, propylene based plastomers, ionomers or a combination thereof, and a barrier layer directly on the coupling layer.

Multilayer structures, multilayer films, and packages formed therefrom

The present invention relates to polyethylene films having a combination of high stiffness and good optics. The cast films have a first layer comprising a linear polyethylene having a density greater than 0.94 g/cmand a melt index less than or equal to 1.3 g/10 min together with a second layer comprising a linear polyethylene having a density greater than 0.94 g/cmand a melt index greater than or equal to 2.0 g/10 min. The second layer is an external layer of the film.
