    Abstract: A polymeric web exhibiting a soft and silky tactile impression on at least one side thereof is disclosed. The silky feeling side of the web exhibits a pattern of discrete hair-like fibrils, each of the hair-like fibrils being a protruded extension of the web surface and having a side wall defining an open proximal portion and a closed distal portion. The hair-like fibrils exhibit a maximum lateral cross-sectional diameter of between 2 and 5 mils, and an aspect ratio from 1 to 3. Methods and apparatus for making the polymeric web utilize a three-dimensional forming structure having a plurality of protrusions being generally columnar forms having an average aspect ratio of at least about 1.

    Abstract: For heat-setting tubular articles (such as can bodies) of an at least partly biaxially oriented crystallizable polymer, preferably a saturated linear polyester such as polyethylene terephthalate, e.g. for thermally processable food containers, a tube of the polymer is fitted over a mandrel and clamped at its ends to the mandrel at a temperature below the glass transition temperature of the polymer. The tube is then heated, e.g. by inserting a heater 28 into the interior of the mandrel, above the temperature to which it is to be heat-set (at least 60.degree. C. above for PET) whereupon it shrinks into contact with the mandrel but is restrained from axial or further radial shrinkage. The tube and mandrel are cooled to below the heat-set temperature and the tube may then be cut into can body sections by knives engaging in circumferential grooves. Contact between the tube and mandrel is released, e.g. by forcing compressed air out through small holes in the mandrel surface to allow the tube and mandrel to be separated. Tubular bodies with one closed end can be heat-set on a mandrel with a correspondingly shaped end.

    Abstract: A method is disclosed for reducing post-molding shrinkage of a hollow oriented polyethylene terephthalate container; the method including the steps of:(1) bringing a polyethylene terephthalate parison to orientation temperature,(2) blow molding the parison to provide a biaxially oriented container with larger dimensions than desired in the final container,(3) heating the blow molded container for a time and temperature sufficient to shrink the container to the desired size whereby substantially all the time-temperature dependent shrinkage is accomplished.

    Abstract: Process for making transparent hollow bodies of terephthalate of polyethyleneglycol in which a preform is made, the preform is cooled rapidly to a temperature at least equal to the crystallization temperature, and is then rapidly expanded to obtain bi-orientation and solidification prior to substantial crystallization of the material. The preform can also be axially stretched during the operation. The apparatus for preforming the process includes a rotatable turret with mandrels, which operates to slightly expand the material on a mandrel.

    Abstract: Polypropylene resin compositions are provided that are useful in the production of biaxially oriented polypropylene films (BOPPs). The resins of the present invention are blends of high crystalline (low solubles) polypropylene homopolymer and an ethylene/propylene random copolymer (RCP). These blends can be used to replace standard high solubles BOPP grade polypropylene homopolymers. In addition, the use of high crystalline polypropylene homopolymers in the blends imparts improved stiffness to the finished films while maintaining good processability of the blends.
