  • Publication number: 20090035593
    Abstract: Coextruded films provide cross directional zoned multiple components side-by-side to one another. Systems and methods relate to coextruding such films. During coextrusion, a first polymer conjoins with a second polymer while a temperature differential is maintained between the first and second polymers. This temperature differential is selected to reduce a difference between the viscosities of the first and second polymers making the viscosity of the first polymer close enough to the viscosity of the second polymer to avoid separation upon coextrusion. Further, the films may form a layer in subsequent lamination to other material layers.

  • Patent number: 7108908
    Abstract: The present invention discloses a multi-layered stretched resin film which comprises a base layer (A) containing 40 to 90 wt % of a polyolefinic resin and 10 to 60 wt % of an inorganic fine powder or an organic filler; and an amorphous resin-containing layer (B) provided on at least one side of such base layer (A), and containing 0 to 85 wt % of a polyolefinic resin and 15 to 100 wt % of an amorphous resin; where the amorphous resin-containing layer (B) has a porosity of 5% or below. Such multi-layered stretched resin film is successfully exempt from being waved or curled due to vehicle contained in offset printing ink during offset printing, and can thus ensure excellent printability.

  • Patent number: 7090916
    Abstract: The present invention provides a paper product for use in sterilizing an area. The paper product contains at least one paper sheet or pellet containing one or more dry chemical materials, one or more dry deliquescent materials, or mixtures thereof. The dry chemical materials are either inactive antimicrobial or biocidal chemical materials or are capable of reacting with another chemical material to produce one or more active antimicrobial or biocidal chemical materials. When the paper product is placed in an atmosphere containing water vapor, the deliquescent material(s) attracts water and dissolves, thereby either hydrating and rendering active the inactive antimicrobial or biocidal chemical material(s), or providing a medium in which the chemical materials will react to produce one or more active antimicrobial or biocidal chemical materials.
