The present invention relates to an integrally blow-moulded bag-in-container (2) having an integrally blow-moulded bag-in-container wherein the same polymer is in contact on either side of the interface between the inner (11) and outer layers (12). It also concerns a preform (1, 1′) for blow-moulding a bag-in-container, having 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 between the two layers. The inner and outer layers are of the same material.

A method of reducing static charge of a plastic container is provided. The method includes providing a PECVD coating of SiCOH, SiO.sub.x or SiOH to an external support surface of the container. The PECVD coating reduces static charge of the container compared to a reference container that is essentially identical to the container except that the reference container is uncoated.

The present invention relates to a device for coating containers with a barrier layer having at least one plasma chamber, which encloses at least one treatment space, in which at least one container with a container interior can be inserted and can be positioned on the treatment space, wherein a gas lance is provided which can be introduced into the container interior and which further acts as microwave antenna, with the plasma chamber being designed to be capable at least of partial evacuation and being designed to fill the container interior at least partially with a plasma and a process gas. The device is designed such that the container can be preheated by means of a plasma, more particularly by means of a microwave plasma, using a noble gas which can be introduced into the container interior through the gas lance.

The present invention provides a delaminatable container capable of inhibiting reduction in aroma constituents of contents. According to the present invention, provided is the delaminatable container comprising an outer layer and an inner layer and having an inner bag which is composed of the inner layer and configured to contract with a decrease in the contents. The inner layer comprises, as an innermost layer, an inner EVOH layer composed of EVOH resin, and the EVOH resin contained in the inner EVOH layer has an ethylene content of equal to or less than 34 mol %.
