摘要： The invention relates to a method for the online monitoring of film quality during a production process for a plastic film, in particular a blown film or a continuously cast film, in which method the film material (1) is fed out of an outlet device (40) that is designed as a melt lug (4) by a transport device (10). The film material (1) cools on or in front of the transport device (10) and the film material (1) solidifies in front of or on the transport device (10).

摘要： Method of making a balloon catheter includes melt-extruding a thermoplastic polymeric material into a tube, cooling the extruded tube, placing the extruded tube within a capture member and biaxially orienting the polymeric material of the extruded tube while simultaneously tapering at least a section of the extruded tube by radially expanding the extruded tube with pressurized media in the tube lumen and axially expanding the extruded tube with an external load applied on at least one end of the tube as an external heat supply traverses longitudinally from a first end to a second end of the extruded tube in the capture member, wherein an overall axial load on the tubing is varied as at least a section of the tube is heated. The method includes cooling the expanded tube to form a tapered biaxially oriented nonporous thermoplastic polymer tubular member and sealingly securing a balloon proximate a distal end of the tubular member.

摘要： A microporous battery separator is provided having a first co-extruded multilayered portion and a second co-extruded multilayered portion. The two portions are bonded together. In a preferred embodiment, the battery separator has two substantially identical multilayered portions bonded together face-to-face. Each of the two multilayered portions has at least one strength layer and at least one shutdown layer. Methods for making the battery separators are also provided. Preferably, a tubular multilayered film is extruded, and collapsed onto itself to form a multilayered battery separator precursor. The precursor is then bonded and annealed before it is stretched to form a microporous multilayer battery separator.

摘要： One or more implementations of a multi-layered bag with reinforced seals include an outer layer or bag and an inner layer or bag positioned within the outer layer or bag. The multi-layered bag further includes a draw tape positioned near the opening of the multi-layered bag. The draw tape can allow a user to at least partially close the multi-layered bag by drawing the layers of the bag together. The multi-layered bag further includes one or more tape seals that bond the draw tape to layers of the bag. The tape seals can be reinforced and include at least seven plies bonded together. One or more implementations further include methods of forming multi-layered bags with reinforced seals.
