Integral two layer preform, process and apparatus for the production thereof, process for producing a blow-moulded bag-in container, and bag-in-container thus produced |
摘要 |
The invention is an integral two-layer preform (1) for the production of integrally blow-moulded bag-in-containers (2). The preform has an inner layer (11) and an outer layer (12), 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. |
