Recyclable laminate

A mechanically recyclable multi-layer laminate comprising:

• (A) at least one first film substrate layer;
• (B) at least one second film substrate layer;
• and
• (C) at least one layer of a polyolefin-based laminating adhesive composition;
• wherein the polyolefin-based laminating adhesive composition for use in producing a mechanically recyclable material includes a mixture of:
• (a) from 40 weight percent to 90 weight percent of (i) at least one saturated polyolefin polyol, and (ii) an optional saturated fatty dimer polyol;
• (b) from 10 weight percent to 30 weight percent of at least one aliphatic multi-functional isocyanate compound,;
• and
• (a)(i), (a)(ii), and (b) amount to 100 weight percent of the composition;
• wherein the adhesive composition layer is disposed on the surface of at least one of the layers of the at least one first film substrate layer, component (A), and the at least one second film substrate layer, component (B), for binding layers (A) and (B) together;
• and
• wherein the at least one first film substrate layer is bonded to the at least one second film substrate layer via the adhesive composition layer.
