Abstract: The present invention provides a resin composition containing a polyolefin resin (A), a metal soap (B), a saponified product (C), and a hydrotalcite compound and/or a hydrotalcite solid solution (D). The resin composition shows superior long-run formability (surface smoothness, suppression of fish eye, pigment dispersibility), suppressive effect on die build-up and superior transparency and gas barrier property when added to a regrind layer during formation of a laminate having the regrind layer. Therefore, the composition is highly useful as an additive for collected materials (regrind) for forming various laminates.
