Multi-layer containers

An extruded blow-molded multi-layer container comprising:

• an inner layer including a high density polyethylene polymer exhibiting:
• a melt flow index ranging between 2-12 g/10 min at 190° C./21.6 Kg,
• a yield strength ranging between 23-28 MPa when stretched at 50 mm/min, at 23° C.,
• an elongation ranging between 500-700%,
• an outer layer including 70%-90% by weight of a high density polyethylene polymer exhibiting:
• a melt flow index ranging between 2-12 g/10 min at 190° C./21.6 Kg,
• a yield strength ranging between 23-28 MPa when stretched at 50 mm/min, at 23° C.,
• a barrier layer disposed between the inner layer and the outer layer, the barrier layer including:
• 78-92% by weight of a homopolymer or copolymer of ethylene,
• 3-10% by weight of a polyamide homopolymer,
• 5-10% by weight of maleic anhydride grafted polyethylene (MAgPE).
