Recycled blends were prepared by mixing, extrusion and blow molding process using recycle of the waste air bag made of LDPE/ PA6/ LLDPE as base material and LDPE-g-MAH (maleic anhydride grafted low-density polyethylene) as compatibilizer. The mechanical, barrier, melt flow properties as well as fracture surface microstructure morphology of the blends of 3%, 8%,12%, and16% (mass fraction) compatibilizer were tested and analyzed. The results showed that LDPE-g-MAH addition significantly improved Nylon and polyethylene blends interface compatibility between the two phases; the blend with addition of 3% to 8% compatibilizer has better barrier properties; the mechanical properties of the blends with addition of 8% to 16% compatibilizer has been significantly improved.
