    摘要： The instant invention provides a method for improving the bubble stability of a polyethylene composition suitable for blown film extrusion process. The method for improving the bubble stability of a polyethylene composition suitable for blown film extrusion process comprises the steps of: (1) providing a polyethylene composition having a density in the range of 0.900 g/cm3 to 0.970 g/cm3 and an relaxation spectrum index (RSI) value in the range of 10 to 100; (2) oxygen tailoring said polyethylene composition; (3) thereby forming an oxygen tailored polyethylene composition, wherein the RSI value of the said oxygen tailored polyethylene composition increases from 10% to 300% of its initial value; (4) thereby improving the bubble stability of said polyethylene composition.

    摘要： The invention relates to a method for determining the thickness of multi-layer films (13) comprising layers consisting of various non-conductive materials. According to said method, the thickness of the multi-layer film (13) is measured by a first sensor (17) and a second sensor (16) and optionally additional sensors, whereby all the sensors take a measurement at the same location under the same conditions if possible. The first sensor (17) and the second (16) or additional sensors generate different measured values for layers of the multi-layer film (13) of the same thickness consisting of the same material (13). The measured signals of the sensors (16, 17) are fed to a computer (18), which determines the total thickness of the multi-layer film (13) and/or the thickness of the individual layers of the multi-layer film (13) from the different measured values of the first sensor (17) and the second (16) or additional sensors.

    摘要： The apparatus includes an extrusion die and further includes a main or primary extruder for the supply of material, such as low density polyethylene, to form the tubing for the manufacture of reclosable packages, bags or pouches. The apparatus further includes at least one secondary extruder, or co-extruder, for the extruding of each reclosable profile onto the tubing. The speed of the co-extruders is controlled so as to control the extrusion of the reclosable profiles.

    摘要： A conductive polyolefin film characterized by acceptable physicals, no pinholes, and a resistance through its thickness of less than about 100 ohms, preferably less than about 10 ohms, and a method for making the same. The film includes a structural polymeric material such as a polyolefin blended with conductive additives such as carbon filler to produce desired characteristics. The film may be surface treated to enhance its ability to bond to other materials. The process includes combining and blending a plurality of resins with different conductive carbon loaded polymers, drying the conductive resin mix to a selected moisture content, converting the conductive film resin into a fluidized solid, and forming a film. The film and method of the present invention provide films suitable for use in a range of applications, including as conductive media for electrodes in batteries and capacitors or in desalination/deionization systems. The film has an inherent property of Positive Temperature Coefficient Resistance that may be selected by selecting the ratio of structural material and conductive material, wherein the film increases in resistance at selectable voltages and limits current at a particular point, protecting batteries from short circuit, for example.
