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&#x3e;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.

Foamed blow molded article

The invention is directed to HDPE having a quotient of melt strength according to ISO 16790:2005 and apparent viscosity according to ISO 11443:2014 (melt strength/apparent viscosity)&#x3e;2 cN/k&#xb7;Pa&#xb7;s and &#x2264;30 cN/k&#xb7;Pa&#xb7;s. In a preferred embodiment, HDPE with an Ml in the range between &#x2265;0.1 and &#x2264;10 a density in the range between &#x2265;935 and &#x2264;970 kg/ma gel fraction less than 5% and an elasticity (ratio of G'/G&#x2033; at 0.1 rad/sec) between &#x2265;0.6 and &#x2264;10 is obtained by chain branching HDPE with an Ml in the range between &#x2265;10 and &#x2264;100 a density in the range between &#x2265;935 and &#x2264;970 kg/mand an elasticity (ratio of G&#x2032;/G&#x2033; at 0.1 rad/sec) between &#x2265;0.01 and &#x2264;0.2.
