It can be used on amorphous raw materi- als such as cyclic-olefin-copolymers (COCs), cellulose triacetate (CTA), PMMA or polycarbonate, as well as semi-crystalline polymer films like PET, PP and PA. Higher dielectrics US researchers have found that biaxially oriented multi- layered films could have enhanced dielectric properties – making them potentially useful in high energy density film capacitors. The films, made of PET and a PVDF co-polymer, took advantage of the synergistic effects of microlayering and biaxial orientation, according to the researchers from the Center for Layered Polymeric Solutions at Case Western Reserve University in Cleveland, Ohio. Polymer film capacitors are attractive devices due to their low cost, simple construction, high operating voltages and long lifetimes. The major disadvantage of polymer film capacitors is their low energy density resulting from the low dielectric constant (K) of Lindauer machine direction) while it relaxes in the transverse polymers that are typically used as the insulating Dornier direction.

  • process feature | Water-cooled blown film eration of microcrystals – both reasons for haze – is restricted,” said the company. it also claims that the process can be used to make improved vacuum bags and thermoforming film, saying that conventional methods of cast and blown film have their downsides. While cast film techniques have quite good cooling, high producitivity and good tolerances, they can also have disadvantages, including: edge trims, high investment, restriction to axial orientation, high resin cost and curl. While blown film techniques can solve some of these – notably by cutting out edge trim and cutting invest- ment – they also have shortcomings: bad cooling, low productivity, radial orientation and low transparency are just a few. Plamex says that its iC technique combines the advantages of the two processes. “the film stays highly transparent and can be thermoformed to deep trays with rectangular shape and small loss of thickness in the lower edges,” says the company. Because different resins freeze at different tempera- tures, a curl in the direction of the resin that freezes at lower temperatures often occurs in asymmetrical layer combinations (such as PA/Pe). Using intensive cooling, as on the iC line, this process can be eliminated or even reversed – so that it curls towards the outer PA layer. this can help to make the bags easier to open. in principle the iC process is blown film extrusion modified by water cooling, which can banish edge cuts. the company claims that throughputs of up to 500kg/ hour are possible.The Aquarex PVC replacement Seven-layer productsline blows film One company, Melitek, has teamed up with W&h to Dr Collin of Germany also offers water-cooled blowndownwards and develop products. its meliflex range of polyolefin resins, film machinery, and has developed lines to make three-,quenches it based on tPe and tPO, was specifically developed for five- and seven-layer products that can compete withwith water pharmaceutical packaging and medical devices. it is plasticised PVC.instead of air ideal for medical applications as it is produced from the main application of its Bl 185/400 and Bl chemically inert raw materials. its film grades, meliflex 185/600 is within the medical field, for either infusion Xf, can be processed using either cast or blown film bags or secondary packaging. the lines can produce extrusion. heavy-walled bubbles up to 300 microns thick. layflat PP-based grades of the material, specially devel- widths of 30-500mm have been achieved to date, says oped for infusion bags, have been run on W&h’s the company.
