Abstract

See full text

The present invention relates to an integrally blow-moulded bag-in-container (2) and preform(1, 1′) for blow-moulding the bag-in-container. An inner layer (11) and an outer layer (12) are used, wherein the preform forms a two-layer container upon blow-moulding, and wherein the obtained inner layer of said container releases from the thus obtained outer layer upon introduction of a gas at a point of interface (14) between the two layers. At least one of the inner and outer layers includes at least one additive allowing both inner and outer layers to reach their respective blow-moulding temperatures substantially simultaneously.
