High escr glossy plastic containers

A multilayer plastic container having a wall structure comprising at least two layers, wherein one of said layers is configured to provide an internal layer having a internal wall surface and the other said layer is configured to provide an external layer having an external wall surface, one of said layers consisting essentially of a metallocene-produced medium density polyethylene (mMDPE) resin having a density within the range of 0.925-0.94 g/cm3 and a melt index, MI2, within the range of 0.5-2.5 g/10 min. and representing from 10-30 wt. % of the total weight of said plastic container, and the other said layers prepared from a high density polyethylene (HDPE) resin, said plastic container having an internal or external surface having a gloss of at least 40 as provided by the layer of medium density polyethylene and having an environmental stress crack resistance as measured by the time to rupture of at least 30 days.

A multilayer plastic container having a wall structure comprising an internal layer formed of a high density polyethylene (HDPE) resin having an internal wall surface and an external layer having an external wall surface formed of a metallocene-produced medium density polyethylene (mMDPE) resin having a density with the range of 0.925-0.94 g/Cm3 and a melt index, MI2, with the range of 0.5-2.5 g/10 min. and having a thickness of from 5-30% of the total thickness of said wall structure, said plastic container having an external surface having a gloss of at least 40 as provided by the external wall surface of said metallocene-produced medium density polyethylene and having an environmental stress crack resistance as measured by the time to rupture of at least 30 days.
