Methods and systems for making a film made of dynamically vulcanized thermoplastic elastomeric material are provided herein. The subject methods and systems achieve dimensional stability of an elastic film by applying thermal treatment as part of the film making process and enhance the shrinkage of the film by intentionally with stretching the film while hot and freezing the film in the stretch. The systems and methods are useful in controlling shrinkage of DVA post film extrusion.

A medical balloon is provided for which the working surface may be identified during an interventional procedure with enhanced precision. Related methods of manufacturing such a balloon are also disclosed.

A process includes: supplying a main resin from outer and inner flow channel, to a joined flow channel at a predetermined supply velocity for a predetermined time; supplying a second resin from a middle flow channel to the joined flow channel simultaneously with the main resin at a predetermined supply velocity for a certain time within the predetermined time; and sliding a shut-off pin to bring the pin forefront to a predetermined position near an outlet of the inner flow channel, open to the joined flow channel, before the second resin is supplied, or during a time starting after a time from the start of the second resin supply and ending with the termination of the supply, so that the velocity of main resin supply from the inner flow channel to the joined flow channel is reduced to a predetermined level by adjusting the degree of aperture for the outlet.

A method of forming and filling a container. The method includes the steps of placing a preform in fluidic communication with an outlet of an injection device of a forming station and forming a container by expanding the preform during a forming step, wherein a forming liquid is injected into the preform through the outlet to expand the preform into the container. The forming liquid is a cleanable liquid. The method further includes a step of transferring the formed container to a concentrate filling station, separate from the forming station and a step of filling the concentrated liquid in the container already containing the cleanable liquid. The step of filling the concentrated liquid is performed in the concentrate filling station.

A formulation for producing a polymeric material including polypropylene, a chemical blowing agent, and optional components as described.

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 blow molding device of the invention includes a pair of blow cavity split molds (50A, 50B), a chuck member (80) that chucks a mouth portion (20) and conveys a preform (10A), a blow core mold (70) that includes a tubular portion (71) which surrounds circumferences of the mouth portion and a flange (25) and introduces blow air into the preform, and a pair of projecting members (60A, 60B) which have a halved ring shape and are provided detachably on each upper surface of the pair of blow cavity split molds. Each of the pair of projecting members includes an airtight sealing portion (61) which is in contact with a lower end face of the tubular portion of the blow core mold, and a positioning portion (62) which positions the flange of the preform.

A connection, and methods of making an using such a connection, the connection comprising a first layer; a second layer concentrically disposed about the first layer; and a laser-induced seal between portions of the first and second layers; wherein the laser-induced seal provides a fluid-tight engagement between the first and second layers. As to particular embodiments of the connection, the first layer can be incorporated into a first conduit and the second layer can be incorporated into a second conduit.

Disclosed is a processing unit for an electromagnetic processing of plastic parisons and including a series of processing modules, each including a hollow housing, a light emitting assembly and a dehydration circuit for preventing each hollow housing from moisture via a dehydrated fluid. The dehydration circuit extends outside the main body, where the circuit can be in fluid communication with a source of pressurized fluid, on which are disposed a fluid dehydration unit and fluid circulation unit for forcing the dehydrated fluid to feed the respective hollow housings.

The invention is an integrally blow-moulded bag-in-container and preform and a method for making it. The bag-in-container has an inner layer forming the bag and an outer layer forming the container, and a mouth fluidly connecting the volume defined by the bag to the atmosphere. The container further has at least one interface vent fluidly connecting the interface between inner and outer layers to the atmosphere, wherein the at least one vent runs parallel to the interface between inner and outer layers and opens to the atmosphere at a location adjacent to, and oriented coaxially with the bag-in-container's mouth. Processes for manufacturing a preform and a bag-in-container as defined above are defined too.
