| 20120009370 | MULTILAYER HEAT SEALANT STRUCTURES, PACKAGES AND METHODS OF MAKING THE SAME - The embodiments of the present invention relate to multilayer thermoplastic structures having improved sealability and tearability. More specifically, the present invention relates to a multilayer heat sealant structure having at least three layers that may be coextrusion coated or otherwise laminated to a substrate, such as metallized polymeric material, foil, or other substrates. | 01-12-2012 |
| 20110274919 | High Release Nip Roll Assembly - Disclosed herein is a high release nip roll assembly comprising a nip roll with a covering comprising a high release material. The release properties of the nip roll material can permit intermittent contact without the coating adhering to the surface of the roller and wrapping the nip. Also disclosed is a high release nip roll belt made of a high release material on the top and bottom surfaces of the belt. The belt can be positioned at each end of a nip roll so that areas of the nip roll typically vulnerable to molten thermoplastic material contact are protected by a belt. Also disclosed is a belt making apparatus. Also disclosed is a frame assembly for moving a belt longitudinally along a nip roll. Also disclosed is a rope guide assembly for threading a belt in relation to a nip roll and at least at least one belt roller. Also disclosed is a jig for joining a leading section of a belt and a trailing section of a belt. | 11-10-2011 |
| 20100272938 | Hydraulically-Formed Nonwoven Sheet with Microfibers - In a first embodiment, a hydraulically-formed nonwoven sheet, a package comprising such sheet, a method of packaging a medical device using a package with such sheet and a method of manufacturing such sheet are provided. This nonwoven sheet comprises first and second non-cellulosic polymeric fibers. The first non-cellulosic polymeric fibers have an average diameter less than about 3.5 micron, an average cut length less than about 3 millimeters and an average aspect ratio of about 400 to about 2000; the second non-cellulosic polymeric fibers have an average diameter greater than about 3.5 micron and an average aspect ratio of about 400 to about 1000. In a second embodiment, a hydraulically-formed nonwoven sheet is provided. This nonwoven sheet comprises binding material, non-cellulosic polymeric fibers and cellulosic based materials. The non-cellulosic polymeric fibers have an average diameter less than about 3.5 micron, an average cut length less than about 3 millimeters and an average aspect ratio of about 400 to about 2000. The second nonwoven sheet has a bacterial filtration efficiency of at least about 98%. | 10-28-2010 |
