CONTAI fy EUS ANH TRANSPORTATION Industrial Tapes Find N e w Uses in V a r i e d Fields One of the newer applications of industrial adhesive tapes is for packaging chemicals. The tape is applied around the joint of the lid with the jar, can, bottle, or other container. Thus, Merck & Co. seals off glass containers containing liquid vitamins, using a tape with brilliant white enamel effect, both utilitarian and pleasing to the eye. This and other applications of such tapes were demonstrated before a group of technical and business journal editors at the plant of Industrial Tape Corp., subsidiary of Johnson & Johnson, New Brunswick, N. J., on May 17. Company officials said that there are eight basic uses for such tapes, which are made usually of paper, cloth, cellophane, or vinyl films: masking, holding, sealing, packaging, stenciling, protecting, reinforcing, and identification. One of the largest consumers is the automobile manufacturing industry, where industrial and kraft paper are used to mask chromium trim, window glass, and headlights in the spray-painting process. Tape manufacturers were not aware of the great potentialities of this use until a few years ago when they received repeatedly larger orders for such tapes from the Hudson Motor Co. and finally learned of the masking use. One of the key factors in such a tape is the adhesive. In some instances a "quick stick" action is wanted, whereas in other uses permanency of adhesive powers is the main consideration. The chief raw materials of the adhesives are natural raw rubber, a resin, and solvent such as toluene. About %r/r of the toluene is recovered for re-use while perhaps l.5c/c is absorbed into the adhesive. The adhesives are applied on large sheets of paper, cloth, cellophane, or other parent material, then cut, usually by multi-knives into industrial tape. Much of the machinery is automatic. As to the application by Merck & Co., it was explained that some powders or granules in containers cake or deteriorate if exposed to air. Sealing with industrial tape keeps the moisture out by making the containers airtight. The tape is easily and quickly applied either by hand or a taping machine. It adheres instantly and securely on contact with the metal tops of containers and conforms to the contours of the ridges on the containers, without waves or wrinkles. Containers are easilyopened by removing the tape and can be resealed with the same tape after partial removal of contents. With a choice of several bright colors, the attractiveness of the package can be enhanced to suit the taste of the packer and consumer. The majority of uses of industrial tape are of a temporary nature, such as for holding interior equipment of a refrigerator during shipping, though several uses VOLUME

are permanent, such as fastening mirrors to metal shells in women's vanity cases. An unusual use during World War II was in lining the various passages in a battleship with luminescent tape so that the crew could find its way around when blacked out in hostile waters. Esso O r d e r s Supertankers Negotiations for construction of six supertankers with a volume capacity of 230,000 barrels each were completed recently by the Esso Shipping Co., affiliate of Standard Oil Co. (N. J.). The new ships will bring to 18 the number of such vessels contracted for in the U. S. in a little more than three years. The six tankers will be built by the Newport News Shipbuilding and Dry Dock Co., Newport News, Va., and are expected to be completed by the beginning of 1953. The first of the vessels is scheduled for delivery in August 1952. Each of the new tankers will have a haulage capacity about 75% greater than the T-2 type tankers built during the war. The sixe additional tankers will have a service speed of about 16 knots and a deadweight of 26,800 tons. Each will be 628 feet over-all in length and have 82 feet 6 inches of molded beam, 42 feet 6 inches of molded depth to the upper deck, and normal complement will be about 48. The tankers will be of single deck type with steel welded and riveted construction. Each will have a single screw driven by a high pressure-geared steam turbine capable of developing 12,500 shaft hp. at 112 r.p.m. Fiber t o Replace Restricted Steel S t r a p p i n g Restrictions placed on the use of steel strapping on packages weighing less than 90 pounds by National Production Authority's Order M-59 make A. J. Gerrard & Co.'s new Fiberstrap one of the timeliest new products on today's markets, according to company spokesmen. This new strapping stands a pull of 275 pounds, retains its original tensile strength and ductility under normal conditions, and provides uniform tension. The strap has a soft, smooth surface that is nonabrasive and nonadhesive and can be safely applied around units that are vulnerable to other types of strapping. Uniform, reinforcing tensioning of Fiberstrap with the Steelbinder tool makes an adhesive surface unnecessary. Fiberstrap is produced in standard 8 / 4 inch width, 0.040-inch thick. It is available in 25-pound coils, 1750 feet long. C 1
