    摘要： A method of making a microporous laminate sheet having a first film layer and a second layer. The first film layer includes a pore initiator and is bonded to the second layer in order to form a laminate sheet. The laminate sheet is then stretched using at least one CD intermeshing stretcher and at least one MDO stretching unit. Methods of making a microporous film is well as a microporous film laminate are also provided, along with an apparatus for stretching a film or laminate.

    摘要： An apparatus for producing a thermoplastic film having low-birefringent, low stress and at least one polished surface for optical media applications as well as low stress film for non-optical applications using a continuous extrusion process. The apparatus consists of a novel calendering roll in a calendering roll stack wherein, at least one roll consists of an inner steel shell, a resilient covering over the inner steel roll and a multi-layer metal sleeve outer covering of at least two layers. The metal sleeve preferably consists of three layers. The inner layer of the multi-layer outer sleeve is preferably nickel, the intermediate layer is preferably copper and the outer layer is preferably chrome with a highly polished surface. The film produced by the process has a retardation value (birefringence times thickness) of less than about 100 nanometers and a surface roughness of less than about 4 microinches. The process is a continuous extrusion process for producing such film or sheet and does not require any further finishing operations.

    摘要： Recycling polyolefin material, e.g. biaxially oriented polypropylene film, coated with a chlorine-containing polymer, such as polyvinylidene chloride homopolymer and/or copolymer, and having a primer therebetween. First, a caustic solution is formulated containing from about 0.1 wt. % to about 50 wt. % caustic, and from about 0.05 wt. % to about 1.0 wt. % of a wetting agent. The formulated caustic solution is heated to a temperature from about 25.degree. C. to about 140.degree. C. The polyolefin material is soaked in the heated caustic solution until the material is separable from the chlorine-containing polymer. After separating the polyolefin material from the chlorine-containing polymer, the material is reprocessed into desired product by extrusion, molding or other product forming process.
