Greater protection for products packed in tin cans has been achieved t h r o u g h the development of synthetic rubber sealing compounds, the research division of American Can Co. announced recently. One type of synthetic rubber unaffected by solvents is now used for the compound in cans for cleaners, insecticides, and fire extinguisher fluids: a synthetic rubber with a molecular structure which resists the softening action of fats and oils is used for meat, fish, and edible oils; another type, resistant to high temperatures and pressures, is selected for fruit and vegetables which must undergo processing. Because of the advantages offered b y the widely varying properties of t h e several types of synthetic rubber, it i s unlikely that natural rubber will ever regain its prewar importance in metal container manufacture, in the opinion of the company's scientists. While most people have been opening tin cans for years without realizing they contain a sealing compound, because it cannot be seen unless the end s e a m s are opened, it nevertheless performs the very necessary function of closing t h e last possible microscopic opening between the ends and the body of a can.

Production of glass containers in August totaled 9.5 million gross, according t o the Bureau of the Census, Department of Commerce. This total was 7 % greater than output in July but was 1 1 % below t he 10.7 million gross produced in August. 1946. Production of wide m o u t h containers increased 3 3 % over July while narrow neck containers showed a 5 % dcîcline from July, accounted for principally by decreases of 4 7 % and 3 6 % for returnable and nonreturnable beer bottles.

Nu-Chromseal tape, developed by Pittsburgh Plate Glass Co., 632 Duquesne Way, Pittsburgh, Pa., is being m a d e available in three thicknesses. It is not affected by gasoline, oil, or water and may be used where required baking teniperatures run as high as 375°. I t is described as adhesive on both sides, clean t o handle, and high in dielectric values. I n addition to aircraft applications it is recommended^ for boat and conta;ne? sealing.
