Abstract:
The invention is directed to a blow molded article. The article comprises at least three layers wherein layer A comprises polymer, layer B comprises a foam composition comprising high density polyethylene having a quotient of melt strength and apparent viscosity>2 cN/k.Pa.s and layer C comprises polymer wherein the layer comprising the foam composition is enclosed between two layers A and C and wherein the melt strength is determined as described in ISO 16790:2005 and the apparent viscosity is determined as described in ISO 11443:2014 and wherein the foam composition is produced with a physically blowing agent.
