  • Patent number: 7419570
    Abstract: The present invention discloses a process and a method providing a high bulk tissue which is both strong and soft. Specifically, it has been discovered that certain low pressure printing technologies may be used to deliver a bonding material to the surface of a high bulk paper web such as an uncreped, through-dried web. The bonding material may be applied to the web either before, during or after the web is softened with a mechanical straining process which will decrease the web bulk by no more than 20% of the initial bulk in order to increase the web softness. The web may be softened by any of a variety of mechanical straining processes such as, for instance, microcreping, microstraining, rush transfer, or other low-compressive softening methods. The cured bonding material on the web may not only increase the bulk of the web when dry and wet, but also increase the wet resiliency and the wet strength of the web.

  • Publication number: 20080163992
    Abstract: The invention provides a low density paperboard material and associated method for use in producing an insulated container, and is especially well-suited for making cups. The paperboard material comprises a paperboard web including wood fibers and expanded microspheres, and has a relatively low density ranging from about 6 to about 10 lb/3 MSF/mil, a relatively high caliper ranging from about 24 to about 35 mil, and an internal bond strength of at least about 80×10?3 ft-lbf., preferably at least 100×10?3 lft-lbf. For applications such as cups the material is also coated on one or both sides with a barrier coating, preferably low density polyethylene, to limit liquid penetration into the web. The low density paperboard material of the invention is convertible for manufacture of containers, particularly cups, and exhibits insulative properties comparable to higher cost materials conventionally used to make cups.

  • Patent number: 7306699
    Abstract: A method for application of compositions onto non-woven webs, such as paper webs, and to products made from the process. In general, the method includes applying a composition to a non-woven web using a non-impact printer, such as an ink jet printer. The composition is applied, in one embodiment, as droplets that remain as discrete shapes on the substrate. In this manner, treated areas and untreated areas are formed on the web. Through this process, the water absorption and control properties of the web can be adjusted as desired while simultaneously treating the web with a composition that improves the physical properties of the web, improves the chemical properties of the web and/or can provide a benefit to a user if transferred from the web.

  • Patent number: 7182837
    Abstract: A process and method which ‘locks in’ three-dimensional texturing added to a paper web by virtue of an adhesive material which is printed onto the surface of the web is generally disclosed. The adhesive may be applied to the web either before, during, or after the web is molded to increase the surface texture. The adhesive may be applied at relatively low pressure so as to preserve surface texture without significant deformation of the web. The cured adhesive material inhibits the web from reassuming a two-dimensional state or may contribute additional texture by rising above the surface of the web. This process may not only increase the bulk of the web when dry and wet, but also increase the wet resiliency, the wet strength, and the tactile properties of the web.
