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.
La présente invention concerne une caisse-outre (2) moulée par soufflage d'un seul tenant et une préforme (1, 1') pour mouler par soufflage la caisse-outre. Une couche interne (11) et une couche externe (12) sont utilisées, la préforme formant une caisse à deux couches après moulage par soufflage, et la couche interne obtenue de ladite caisse se séparant de la couche externe ainsi obtenue lors de l'introduction d'un gaz à un point d'interface (14) entre les deux couches. Au moins une des couches interne et externe comprend au moins un additif permettant aux deux couches interne et externe d'atteindre leurs températures de moulage par soufflage respectives de manière sensiblement simultanée.
