Disclosed is a composition comprising a blend of 1 wt. per cent to 20 wt. per cent poly-lactic acid and polyethylene terephthalate, wherein the composition has an intrinsic viscosity of greater than 0.7 dl/g to about 1.5 dl/g, and at least one of an axial Young's modulus of at least 210000 psi and a radial Young's modulus of at least 410000 psi; and wherein the poly-lactic acid has a number average molecular weight (MW) of 50,000- 110,000. Also disclosed is a packing material and consumer product comprising the composition and a method for making a consumer packaging by blow-moulding the polymer blend.
