  • Patent number: 6953148
    Abstract: A bag comprises an upper chamber and a lower chamber. The upper chamber comprises an inlet end defining an inlet opening. The lower chamber defines a lower chamber interior volume less than the upper chamber interior volume. A strainer is between the bottom end of the upper chamber and the top end of the lower chamber. The strainer places the upper chamber interior volume in fluid communication with the lower chamber interior volume. The bag wall may define an outlet port. A filter patch may be attached to the bag wall to cover the outlet port. The filter patch may be adapted to entrap airborne particles having a diameter of one micron or greater carried by air passing from the bag interior volume through the filter patch. The bag may be useful in enhancing the detectability of and in reducing the exposure to contaminants that may be present in mail deposited in the bags.

  • Publication number: 20050158517
    Abstract: A laminate for use as a floor underlayment material includes a film disposed on at least one surface of an expanded foam web. The foam web includes a plurality of ribs projecting from one surface of the web in a length direction thereof so as to define a corrugated surface. The film is disposed on the surface of the foam web opposite the corrugated surface. The film is preferably formed from a high density polymer so as to enhance the moisture barrier properties of the laminate. When installed between a subfloor and finish flooring, the laminate defines channels which enable moisture emanating from the subfloor to be directed out from the flooring system.

  • Patent number: 6895732
    Abstract: A packaging apparatus includes a pair of rolls forming a nip through which two web portions are passed with an item to be packaged between the web portions. The rolls include resiliently compliant roll portions that deform to accommodate the thickness of the item, and the roll portions press the web portions to seal them together in peripheral regions surrounding the item and to center the item between the webs in the thickness direction. The apparatus also includes side seal devices that traverse inwardly toward the item to seal the webs together close to the item's opposite side edges to prevent the item from laterally shifting. The web portions may have cohesive disposed on their facing surfaces such that the web portions adhere to each other with pressure but tend not to adhere to the packaged item or other surfaces.

  • Patent number: 6887912
    Abstract: An expanded cellular ethylenic polymer product is provided from an irradiated, noncross-linked linear ethylenic polymer. Linear ethylenic polymers can be irradiated at ambient conditions sufficient to introduce branching in the polymer in the absence of detectable cross-linking as indicated by the absence of gels. The irradiated linear ethylenic polymer is compatible with highly branched low density polyethylene and, when mixed therewith, produces a resin having a single broad based melting temperature range as determined by direct scanning calorimetry, which indicates that the polymers in the mixture have similar crystallization behavior suitable for producing low density foams by extrusion foaming. The linear polymers can be obtained from recycled shrink wrap film. Low densities of from 0.7 to less than 4 pcf can be achieved. The foams typically have improved tear resistance as compared to previous products prepared from low density polyethylene, at comparable low densities.

  • Patent number: 6820835
    Abstract: A device for rotating a web material roll supported on a reel shaft having a pair of ends. The rotating device includes a female drive member coupled to one end of the reel shaft and defining an opening having a non-circular perimeter, such as a square opening. Also included is a male drive device having a rotatably powered drive shaft having an end that is congruent to the non-circular perimeter of the opening in the female drive member. The non-circular perimeter allows the reel shaft, and web material roll, to be positively rotated during unwinding. A telescoping assembly of the male drive device is capable of extending the drive shaft into the opening so as to allow co-rotation of the shaft and female member. An optional roll supporting cart may be employed to rotatably support the web material roll when aligning the male and female drive members.

  • Publication number: 20040229030
    Abstract: There is provided a multi-layered foamed article. The foam article has a layer of foam material on either side of an inner peel layer disposed roughly in the middle of the foam. The portion of the foam in closest proximity to the peel layer is subjected to the greatest amount of heat during extrusion forming mostly large open cell foam. The foam near the surface of the multiplayer foam article is cooled by the atmosphere or contact with cooling surfaces and comprises mostly small closed-cell foam. There is also provided a method for making a multi-layer foamed article by co-extruding an inner peel layer sandwiched between two expanded layers of a foam material. Each of the expanded foam layers on either side of the peel layer of the article is easily peeled or stripped from the peel inner layer and the multi-layer article is converted into a foamed article with absorbing characteristics on one side and non-absorbing characteristics on the other side.
