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.

Multilayer structures with enhanced adhesive bonding force and articles comprising the same

A process comprises (i) providing an isocyanate component A that is a reaction product of an aliphatic polyisocyanate, an aromatic polyisocyanate, an aliphatic polyester polyol, and a polyether polyol; (ii) providing a polyol component B comprising an aliphatic polyester polyol and a polyether polyol; (iii) mixing A and B to form a solventless adhesive (SLA) composition component A and component B each comprises an aliphatic polyester polyol having a viscosity from 800 to 6000 mPa·s at 25° C. and a hydroxyl number from 60 to 180 mg KOH/g; the SLA composition has (a) an initial viscosity at 40° C. from 500 to 1600 mPa·s, (b) an increasing viscosity ratio from 100% to 112% of the initial viscosity after the SLA composition stands at 40° C. for 10 min, and (c) an end viscosity at 40° C. from 120% to 210% of the initial viscosity at 40 min after forming the SLA composition.
