Systems and methods are disclosed that include generating a plasma treatment and applying the plasma treatment to end contact surfaces of a first profile and a second profile in a sterile environment, manipulating at least one of the first profile and the second profile to force contact between the end contact surface of the first profile and the end contact surface of the second profile to permanently connect, join, or weld the end contact surfaces of the first profile and the second profile together, thereby forming a sterile connection between the first profile and a second profile.

A multi-lumen article includes at least two profiles including at least two lumen, wherein the at least two profiles include a first profile and a second profile, the first profile including a first end and a first lumen, wherein the first lumen provides a fluid flow in a first path; and the second profile including a second end and a second lumen, wherein the second lumen provides a fluid flow in a distinct path different than the first path, wherein at least one profile comprises a polymeric material, wherein the first end and the second end are coincidently bonded without a bonding material at an interface at the first end and the second end.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

The invention relates to a ski boot with an element in shell form, which at least partially consists of a plastics compound material, wherein the compound material comprises a mixture of caprolactam polyamide and ionomers, and to a method for the production thereof, such that cations and anions of the ionomers form ion bonds, wherein elastic components of the compound material form a physical network that is soluble between 60° C. and 100° C., and so the element in shell form of the ski boot that at least partially consists of the compound material can undergo thermoforming below 100° C.

A laminated foam sheet having a polyethylene resin foam layer and an antistatic polyethylene layer laminated on one or both sides thereof is produced by coextruding melts for respective layers, wherein the melt for the antistatic layer contains a polyethylene resin, an ionomer resin antistatic agent and a specific amount of volatile plasticizer blend containing an alcohol and a saturated hydrocarbon or a dialkyl ether. The antistatic layer of the obtained laminated foam sheet has specific morphology.

The present invention relates to a method for recycling an intermediate film for laminated glass, comprising a step of separating a layer comprising an A layer and a layer comprising a B layer from the intermediate film for laminated glass (1) comprising at least the A layer and the B layer.

A method for producing a containing system for a liquid dispenser having a dimensionally stable outer container and a collapsible inner container, in the form of a pouch, arranged within the outer container. The method includes starting from the outer container, at least one layer of a pouch material being applied to an inner wall of the outer container. For this purpose, the pouch material is applied in the form of a liquid or powder to the inner wall, where, after solidifying or fusing, it forms a ply of a wall, of the inner container. The ply detaches from the inner wall of the outer container when the inner container collapses.

A method for joining incompatible materials is provided that includes the steps of welding a first component formed of a thermoplastic material and a second component of a porous material to one another to form a subassembly and optionally molding a third component around the subassembly. The method enables the incompatible first component and the third component to be joined to one another, such as to form an electrolyte battery flow frame around an ion exchange material and/or microporous separator material in order to form a separator for an electrolyte flow battery.
