Abstract
The invention is an integral two-layer preform () for the production of integrally blow-moulded bag-in-containers (). The preform has an inner layer () and an outer layer (), wherein the preform forms a two layer container upon blow-moulding, and wherein the thus obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface of the two layers. The melting temperature of the inner layer is greater than or equal to the melting temperature of the outer layer.
