Multilayer structures having improved recyclability

A method for making a recycled structure, the method comprising:

• converting a multilayer structure into flakes, the multilayer structure comprising
• a first layer comprising, based on the total weight of the first layer:
• from 90 wt. % to 99.5 wt. % of an ethylene/alpha-olefin interpolymer having a density of from 0.945 g/cc to 0.970 g/cc, and
• from 0.5 wt. % to 10 wt. % of a compatibilizer, the compatibilizer comprising an anhydride and/or carboxylic acid functionalized ethylene/alpha-olefin elastomer having a density of from 0.850 g/cc to 0.910 g/cc and a melt viscosity of greater than 200,000 cP, when measured at 177° C.;
• and
• a barrier layer comprising a polyamide, an ethylene vinyl alcohol, or combinations thereof;
• and
• forming the flakes into the recycled structure.

A method of producing a recycled bottle comprising:

• compounding an ethylene/alpha-olefin interpolymer having a density of from 0.945 g/cc to 0.970 g/cc;
• an anhydride and/or carboxylic acid functionalized ethylene/alpha-olefin elastomer having a density of from 0.850 g/cc to 0.910 g/cc and a melt viscosity of greater than 200,000 cP, when measured at 177° C.;
• and a polyamide to produce a blend;
• and
• blow-molding the blend into a bottle.
