Abstract
For recyclability in a high value circular recycling material stream, a fluid-tight collapsible polyolefin container comprises a container body () formed of a container laminate () that is folded to a container-like body and fixed by sealing overlapping edge regions () or by butt welding adjacent edges and optionally coated with a sheathing () of polypropylene to form the container body (), said container body () being provided at one open end with a container head formed from polypropylene. The container laminate () is a laminate having at least three layers, an inner polypropylene layer () and an outer propylene layer () and a barrier layer () sandwiched between the outer polypropylene layer () and the inner polypropylene layer (), wherein the barrier layer () comprises at least one polyolefin comprising oriented barrier foil like a monolayer foil () or a coextruded foil (with layers) or a laminate thereof and wherein at least 70% by weight, preferably at least 90% by weight of all polymers of the container are made of polypropylene homopolymer and/or copolymer.
