Abstract: A packaging laminate (10) comprising a core layer (11) and a gas barrier layer (14) of moisture- and liquid-sensitive barrier polymer, e.g. a copolymer of ethylene and vinyl alcohol (EVOH). The packaging laminate (10) preferably has outer liquid-tight coatings (12 and 13) of thermoplastic in order to make for sealing of the packaging laminate by thermosealing. In order to impart increased moisture and liquid protection to the moisture- and liquid-sensitive barrier layer (14), the packaging laminate (10) has a layer (16) of mineral filled polyolefin between the barrier layer (14) and the outer, liquid-tight coating (13) on the one side of the core layer (11). A packaging container produced from the packaging laminate (10) makes for the storage of a packed liquid food, such as juice, wine, cooling oil etc., with so-called extended shelf life.

Abstract: A plastic tube is prefabricated for producing gas-filled filling bodies. The tube comprises an upper film and a lower film which are connected together in superposed relationship along both of their longitudinal edges. The upper film is divided in its center by a longitudinal cut, thus forming upstanding flaps on both sides of the cut. The films are also subdivided into individual pockets by weld seams extending in the transverse direction of the tube at a spacing from each other. The tube can be filled by introducing a filling gas under the film flaps, the open ends of the pockets being closed after they have been inflated in that way.

Abstract: The present invention relates to a catheter device having a dilatation balloon formed from a polymeric material crosslinked by moisture through —Si—O—Si—linkages, and to a method of making the same. The polymeric material is formed by reacting at least one organofunctional hydrolyzable silane with at least one polymer. The crosslinked polymeric structure is ideal for forming more resilient and durable catheter balloons. In particular, the catheter balloons have excellent abrasion resistance.

Abstract: A method for making a crystallized bottleneck of a polyester beer bottle is provided. The bottleneck has no machined screw threads and a length of 0.5-35 mm. To manufacture the crystallized bottleneck, an uncrystallized blank of the bottle is placed in an air-condition environment and a crystallizer is preheated before crystallization. A bunker is loaded with the uncrystallized blank, which is delivered to a blank horse's head via a conveyor belt. A bottleneck portion of uncrystallized bottle blank is then sent into a crystallizer to heat it at high temperature and crystallize it via an arbor transmission chain. The polyester bottle blank having a crystallized bottleneck portion is discharged through output blank horse's head and delivered to another conveyor belt to cool and shape it.

The conductive member shows very stable conductivity in the volume resistivity range of 105 to 1012 ?·cm, the conductivity of which is less dependent on the voltage applied and varies only slightly during continuous energization and upon changes in environmental factors such as temperature and humidity.

Abstract: A method for producing a polymeric film resistant to degradation during sterilization such as gamma irradiation is presented. The method includes the steps of minimizing the number of free radicals formed during sterilization through use of an inert gas and a reactant scavenger within a sterilization pouch, which reactant scavenger may be acid adsorbents which scavenge the acid by-products formed during irradiation. The films retain physical and mechanical properties with long-term storage. The films are particularly amenable for use as packaging laminates in pharmaceutical, food, semiconductor and medical device industries.
