Provided are multilayer structures and articles comprising same. The multilayer structure comprises: a biaxially-oriented polyethylene film comprising a skin layer with a matte surface and a core, the core comprising one or more core layers; a sealant film; and an adhesive adhering the sealant film to the matte surface of the skin layer of the biaxially-oriented polyethylene film. The multilayer structure can exhibit an enhanced adhesive bonding force in comparison to other multilayer structures.

The present disclosure is concerned with a method of forming a seal with a polyethylene based film structure. The polyethylene based film structure has at least one layer formed with an oriented polyethylene having a predetermined melting temperature (T). A conductive heat sealing device provides heat to form the seal, where a first sealing bar of the conductive heat sealing device operates at a first operating temperature of at least 10 degrees Celsius (° C.) below the Tof the oriented polyethylene in the polyethylene based film structure and a second sealing bar of the conductive heat sealing device operates at a second operating temperature of at least 15° C. higher than the operating temperature of the first sealing bar. The seal formed with the polyethylene based film structure retains at least 99 percent of its original surface area prior to forming the seal.

Polyethylene pouch and the fabrication method thereof

A biaxially-oriented polyethylene (BOPE) multilayer film comprises a skin layer with a matte surface and a core, the skin layer with a matte surface comprising, in weight percent (wt %) based upon the weight of the skin layer: (1) from 20 to 80 wt % of an ethylene-based polymer, and (2) from 80 to 20 wt % of a propylene-based polymer; each of the ethylene-based polymer and the propylene-based polymer having a storage modulus, with a difference between the storage modulus of the ethylene-based polymer and the propylene-based polymer of greater than 40 megaPascals (MPa) at 110&#xb0; C., and greater than 18 MPa at 120&#xb0; C.

Biaxially-oriented polyethylene multilayer film with a matte surface

A multilayer film () having excellent mechanical strength and transparency comprise a core layer (), at least two skin layers, and at least two sub-skin layers disposed between the core layer () and the two skin layers. The core layer () comprises at least 60 wt. % linear low density polyethylene (LLDPE). The sub-skin layers comprise at least 60 wt. % low density polyethylene (LDPE). The skin layers comprise at least 80 wt. % of LLDPE wherein the LLDPE comprises C6 LLDPE, C8 LLDPE, or combinations thereof, and each skin layer has a thickness of less than 25% of the overall thickness of the multilayer film (). The multilayer film () comprises at least 0.1 wt. % ultraviolet stabilizer.
