For recyclability in a high value circular recycling material stream, a fluid-tight collapsible polyolefin container comprises a container body (5) formed of a container laminate (1) that is folded to a container-like body, sealed in the overlapping edge regions (2, 3) and coated with a sheathing (4) of polyolefin material to form the container body (5), said container body (5) being provided at one open end with a container head formed from polyolefin material. The container laminate (1) is a laminate having at least three layers, an inner polyolefin layer (6) and an outer polyolefin layer (8) and a barrier layer (7) sandwiched between the outer polyolefin layer (8) and the inner polyolefin layer (6), wherein the barrier layer (7) comprises at least one polyolefin comprising barrier foil like a monolayer foil (71) or a coextruded foil (72 with layers 72a, 72b) or a laminate thereof and wherein at least 90% of all polymers of the container are made of polyolefin of the same kind.
A fluid-tight collapsible polyolefin container that comprises a container body formed of a container laminate, said container laminate being folded to a container-like body and sealed in the overlapping edge regions, said container-like body having an outer surface coated with a sheathing of polyolefin material to form the container body, said container body being provided at one open end with a shoulder/head formed from polyolefin material, wherein said container laminate is a laminate having at least three layers, an inner polyolefin layer and an outer polyolefin layer and a barrier layer sandwiched between the outer polyolefin layer and the inner polyolefin layer, wherein the barrier layer comprises at least one, optionally coextruded, polyolefin comprising oriented barrier foil and wherein at least 90% by weight of the container are made of polyolefin of the same kind.
