Abstract: A polyolefin film for use as a sterilization wrap material which includes a film with a thickness of from about 0.005 mm to about 0.2 mm and having a plurality of discontinuous thinned regions. The thinned regions constitute at least about 25 percent of the surface area of the film. The thickness and area of the thinned regions are adapted to permit the passage of steam and water vapor through the film during steam sterilization. The film is made by a method which involves extruding a molten polyolefin film at a first temperature and passing the molten film through a nip. The nip includes an anvil roll and a pattern roll. The anvil roll has a smooth surface and the surface of the pattern roll is maintained at a temperature which is at least about 150.degree. C. lower than the first temperature and is selected to prevent sticking of the film to either roll.

Abstract: An improved method is disclosed for the fusing, joining or seaming of cellulosic materials. The method utilizes a hydroxide solution of selected organometallic compounds or metal oxides to rapidly crosslink opposing, overlapping cellulosic surfaces to provide secure seams. In particular, the invention is directed to the production, either on-line or off-line, of tubular cellulosic casings for the manufacture of sausages and sausage-like products. The seams according to this invention have such high shear strength that extremely narrow bond widths are possible. The narrowness of the bond site eliminates or minimizes striping or discoloration of the finished product.

The laminate also may have pigments if desired. Such laminates are useful for garments.

Abstract: A lightweight structurally sound casket formed preferably of a sandwich construction using a core of an open cell or honeycomb patterned material and fluid resistant surface elements. The casket is comprised of a body containment portion and a lid portion, each of which has the sandwich construction as the main structural element. The open cell material is structurally enhanced by being sandwiched between first and second stabilizing surface elements in both the body containment portion and the lid portion. In addition to the stabilizing surface elements, an aesthetically pleasing material is adhered to the outer portions of the body containment section and lid so that the casket has an attractive appearance. The body containment portion is constructed from rectangular pieces of the open cell material and stabilizing surface elements by folding the same into a box-like configuration.

Abstract: A joint-sealing strip is made of soft foam material, with an impregnation leading to delayed recovery. In order to obtain a simple structure combined with an advantageous design especially with respect to technical handling, the impregnation varies over the width of the joint-sealing strip, namely in a marginal longitudinal area. A strengthened impregnation is made preferably extending over the total thickness in the marginal longitudinal area, in such a manner that upon release of the recovery, a profile rising toward a longitudinal center line of the joint-sealing strip is obtained.

Abstract: A novel fibrous non-woven composite is provided that comprises as a first component substantially continuous coarse spun-bonded filaments of a thermoplastic polymer which exhibit molecular orientation, and as a second component fine discontinuous melt-blown microfibers of a thermoplastic polymer. The fibrous components are well admixed through their placement following their formation on the same equipment to form an integrated non-woven deposition in the absence of a discrete phase boundary between substantially homogeneous concentrations of the components, and are subsequently thermally bonded to form a unitary structure. The continuous coarse spun-bonded filaments provide good strength for a supporting function throughout the non-woven composite, and the fine discontinuous melt-blown microfibers perform an uninterrupted filtration and/or moisture transport function throughout the non-woven composite. The resulting product is useful in diaper, medical, and clothing applications.
