The invention is an integrally blow-moulded bag-in-container obtainable by blow-moulding an injection moulded multi-layer preform. The bag-in-container includes an inner layer forming the bag and an outer layer forming the container, and a single opening, the mouth, fluidly connecting the volume defined by the bag to the atmosphere. The container further includes at least one interface vent fluidly connecting the interface between inner and outer layers to the atmosphere, wherein the bag is anchored to the outer layer at at least one point remote from the single opening and interface vent. The invention also relates to a process and a mould for the production of the blow-moulded bag-in-container.

A parison for being blow molded into a medical balloon for a catheter includes a first tubular layer having a functional modification and a second tubular layer adapted for bonding with the first tubular layer to form the blow molded balloon. Related methods are disclosed.

A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

[Problem] To provide: a method of producing molded article having conductive circuit, whereby a molded article having a conductive circuit following a three-dimensional curved surface can be easily obtained even using blow molding; and a preform having a conductive circuit, used to obtain said molded article having a conductive circuit.

A method to produce a container made of a plastic composition having an inner coating with a higher mechanical stability and/or a better adhesion to the container, includes preparing a plastic composition with at least one base polymer material and at least a first additive comprising globe-like particles having a hardness on the Mohs scale of at least 4,and extrusion blow molding of a container. The globe-like particles, which located on the inner surface of the container, increase the surface area and the hardness of the inner surface of the container. The method also includes applying the at least one metal layer of the inner coating onto the inner surface of the container, wherein the applied metal layer bonds to the globe-like particles of the first additive located on the inner surface of the container.

A balloon in which a rupture in a circumferential direction can be prevented from occurring, and a method of manufacturing the same is disclosed. The balloon is configured to be arranged on a medical catheter, and includes a dilatable cylindrical portion formed with a birefringent polymer material. A ratio of the number of orientation distributions, calculated by dividing the number of orientation distributions of the cylindrical portion in a circumferential direction by the number of orientation distributions of the cylindrical portion in an axial direction, is less than 2.
