  • Patent number: 6436521
    Abstract: Ionomer present in a polyethylene resin from about 1 to 40% by weight of the resin produces superior extruded foam sheet products that approach the pore size and resiliency of foams prepared from chemical blowing agents. The results can be achieved at normal extrusion rates and on standard extrusion foaming equipment. Tear strength is improved so that collapsible foam packaging products can be produced in which the foam body is cut through except for a surface thereof that remains intact to provide a hinge or joint about which the cut foam bodies can be pivoted.

  • Patent number: 6284346
    Abstract: An improved closed-cell foam sheet stock and method for producing constant force characteristics in elastomer cushions. A closed cell foam is formed as a corrugated cardboard with regular cavities and support elements between two surface sheets. The resulting stock material possesses similar flexibility to foam stock but with an elongated force curve. A method for modifying this or other corrugated elastomers for efficient constant force curves is further provided where alternating support members are conjoined or buttressed to fold in controlled sigmoid shape under load. The resulting collapsible truss or space frame structure produces a cushion with improved cushioning, load distribution, shock absorption and resistance from lateral collapse while folding uniformly and efficiently to a smooth, compact and comfortable support under full compression.

  • Patent number: 6238770
    Abstract: A plastic tier sheet is provided for use in layered and stacked arrangements of bottles and similar packages to assist in shipping and handling the bottles and similar packages. The plastic tier sheet includes a center panel and edge flanges extending along edges of the center panel and connected to the center panel by living hinges formed by scoring the plastic sheet along its edges. The edge flanges are bonded to the center panel using the material of the tier sheet, such as by sonic spot welding. The edge flanges are secured tight against the center panel, such that there are no gaps to collect debris or unsanitary manner, but the sonic welded spots are spaced apart to minimize the number of spots required. The plastic tier sheet is characteristically formed without use of separate bonding materials or fasteners, such that there is low risk of parts or pieces falling into the bottles and similar packages being transported.

  • Patent number: 6110564
    Abstract: A humidifier pad with multiple layers of slit and expanded paper laminated together. At least one, and in some preferred embodiments, up to half of the paper layers comprise substantially nonwicking paper and the remaining layers comprise highly absorbent wicking paper. Wick type humidifier pads are particularly useful in humidifiers wherein the lower portion of the pad is submerged in a reservoir of water. The upper portion of the pad, exposed to a flow of air to be humidified, is supplied with water due to the high rate of capillary rise featured by the wicking paper layers. Including non-wicking layers wetted by the wicking layers provide an output capacity comparable to conventionally constructed pads which include all wicking paper layers and an attendant saving of the cost of materials.

  • Patent number: 5998007
    Abstract: A multidirectionally stretch-crazed microencapsulated polymer film having a matrix material and microcapsules which are formed in the matrix material in the form of crazes which are filled with an encapsulated substance (30, 30a) and oriented at least in two mutually intersecting directions X and Y. The filled crazes form a net-like structure. The microencapsulated film is produced by stretching the original film under a controlled rate of stretching in two intersecting directions in an environment of a surface-active substance with or, if necessary, without a material to be encapsulated. When stretching is discontinued, the crazes are closed and encapsulate the material.

  • Patent number: H1955
    Abstract: Films, made of polyethylenes and fillers, and articles made therefrom greater WVTR than previously available films based on conventional Ziegler-Natta based polyethylenes. The polyethylenes are produced in a metallocene-catalyzed production process. The films may be made by a cast film process, and may be made in widely varying filler content, generally polyethylene to filler ratios of 30/70 to 70/30. The metallocene based polyethylenes when combined with filler also permit the extrusion of thinner films leading to lighter weight and softer films. The m-polyethylenes utilized for making such films typically have a Composition Distribution Breadth Index above 50%, a Mw/Mn below 3, and a Mz/Mw below 2.
