Richard P. Carter (Johns-Manville) to Harry B. Rhodes (Union Carbide) Enclosing McCrone Report on Tremolite Migration from Food Wrapping Papers (1973)

Cover letter dated September 21, 1973 from Johns-Manville's Director of Government Relations to Union Carbide, enclosing a April 17, 1973 report by Walter C. McCrone Associates on whether tremolite migrates from talc-filled food wrapping papers (Cyclo-Fil and Cyclo-Sorb) to food. The letter says the wet-roller tests were unreliable because of contamination but that no tremolite was found in meat samples. The report concludes that no significant migration occurred at the filler levels examined.
