  • Patent number: 6936209
    Abstract: Stretched polymeric films can be used in a variety of applications, including optical applications. The stretching conditions and shape of the stretching tracks in a stretching apparatus can determine or influence film properties. Take-away systems can be used to receive the film after stretching. The configuration of the take-away system can, in at least some instances, influence final film properties.

  • Publication number: 20040265575
    Abstract: A simultaneously biaxially stretched polypropylene film having unique properties is disclosed. The properties result from the unique method of making the film and include: a tensile elongation to break in the first stretch direction of at least 110%; a tensile volumetric energy to break in the first stretch direction of at least 18,000 in-lb/in3; and, a variability in film thickness along the first stretch direction, as measured by the standard deviation relative to the average, of less than 10%.

  • Patent number: 6617007
    Abstract: A method and apparatus of forming coreless rolls of pressure sensitive adhesive tape involves the use of a mandrel assembly having a specific circumferential tape supporting segment thereon for winding tape. The circumferential tape supporting segment has a tape engaging surface portion that, in a radial orientation, is compressible yet sufficiently stiff to support the tape as it is successively wound about the mandrel to form a tape roll, and that is sufficiently pliant to permit ready axial removal of a wound tape roll from the shaft. The innermost wrap of pressure sensitive adhesive tape about the mandrel is masked by an adhesive liner. That liner is formed from one portion of a liner/tab segment which had been applied to the tape previously, and prior to winding, the tape is severed, and the remainder of that liner/tab forms an end tab on the outermost end of the previously formed coreless tape roll.

  • Publication number: 20020098372
    Abstract: A method of biaxially stretching a polymeric film along an overbias stretch profile. The method comprises the steps of: ) imparting a sufficiently high temperature to the film to allow a significant amount of biaxial stretch; and b) biaxial tenter stretching the film to a final first direction stretch parameter and a final second direction stretch parameter, wherein at least 75% of the final first direction stretch parameter is attained before no more than 50% of the final second direction stretch parameter is attained, and wherein the final first direction stretch parameter is no greater than the final second direction stretch parameter.

  • Patent number: 6303067
    Abstract: A method of biaxially stretching a polymeric film according to an overbias or overstretch stretch profile to a final first direction stretch parameter and a final second direction stretch parameter to provide a film having uniform properties. First, a sufficiently high temperature is imparted to the film to allow a significant amount of biaxial stretch. The film is then biaxially tenter stretched to a peak first direction stretch parameter that is at least 1.3 times the final first direction stretch parameter wherein the final first direction stretch parameter is no larger than the final second direction stretch parameter. Finally, the film is retracted in the first direction from the peak first direction stretch parameter to the final first direction stretch parameter to produce a film having uniformity of properties in the first direction.
