McCormick Department of Industrial Hygiene and Toxicology The B. F. Goodrich Company Akron, Ohio Subject: B.A.I. Approval of Geon Resin 101 EP De~r Pr. McCormick: I would like to congratulate you on the speed with which you obtained acceptance of Geon Resin 20CK20 for food packaging applications. As you no doubt know, we have been trying to do the same thing on our Geon Resin 101 EP, but so far have not received ap proval. I think that we were incorrect in attempting to handle this matter direct, and that we should have asked you to make the contacts in the first place. Now I am wondering whether you would be willing to carry on from here and attempt to get Geon Resin 101 EP accepted. Enclosed with this letter are copies of all of the cor respondence which has gone on heretofore on this subject. CDS/sc ^Attachments Very truly vours, Clyde D.

In answer to your specific question, the glue used is an ani mal glue. We should have specified the type of glue in our earlier let ter, and want to thank you for your patience and cooperation in this matter. CDS/sc c by sc Yours very truly, Clyde D.

Please furnish this office with more definite information about the glue which is vised as an emulsifier in producing the resin. We are particularly interested in knowing whether it is synthetic or is of animal, fish or vegetable origin. The benzoyl peroxide does not appear to be objectionable. Very truly yours, c by sc R. M.

Department of Agriculture Washington 25, D. C. Attention: Dr. R, M. Mehurin, Chief Laboratory Section Meat Inspection Division Your Reference: YLY- Dear Dr. Mehurin: This will acknowledge your letter of August 31, 1951 written in response to our letter of August 22, 1951. In writing the original letter outlining the composi tion of Geon Resin 101 EP, the statement was made that the addi tives in Geon 101 EP were the same as those in Geon Resin 202. In making the statement, the writer was under the impression that you knew the additives used in Geon Resin 202. The additives used in producing the polyvinyl chloride, Geon Resin 101 EP and the vinyl chloride-vinylidene chloride co polymer, Geon Resin 202 are a benzoyl peroxide type catalyst and glue as an emulsifier. These additives are substantially removed by washing in the final processing of the resins. We regret this oversight in our first letter, and hope that the above information will enable you to complete your records. CDS/sc c by sc Yours very truly, Clyde D.

Address reply to "Chief of Bur. of Animal Industry And refer to August 31, 1951 YLY Mr. Clyde D. Segner B. F. Goodrich Chemical Company Rose Building 2060 East Ninth Street Cleveland 15, Ohio Dear Mr. Segnerr This refers to your letter of August 22 in which you furnish us with a statement of the composition of your Geon Resin ICQ. EP. You state that the composition of Geon Resin ICQ. EP is a polyvinyl chlor ide plus the same additives that are used in your Geon Resin 202. Our records indicate that Geon Resin 202 is a copolymer of vinyl chloride and vinylidene chloride but we have no- record of ary additives in this resin. We would appreciate receiving, from you, information concerning the exact composition of your Geon Resin ICQ. EP and also whether or not our records are correct concerning the present composition of the Geon Resin 202. Very truly yours, c by sc R. M. MEHURIN (signed) R. M.

Mehurin, Chief Laboratory Section, Meat Inspection Div'n United States Department of Agriculture Agricultural Research Administration Bureau of Animal Industry Washington 25, D. C. Dear Mr. Mehurin: We understand that you have been requested to approve a packaging material that will contain Geon Resir 101 EP. We are therefore listing belov the facts concerning Geon Resin 101 EP which we believe to be pertinent to your decision. Geon 1(31 EP is a polyvinyl chloride with no monomers other than vinyl chloride used in its manufacture. The additives, used to control polymerization of Geon Resin 101 EP, are exactly the same as those used in Geon Resin 202, which has already been reported to you and approved by you. The additives used in Geon Id EP are in smaller proportions than in the Geon 202. A comparison of control tests on percent ash content will further confirm this point. The average % ash of Geon 101 EP is .028%, The average % ash of Geon Resin 202 is .053%. The figures listed are average production data over the same 4-month production period. Lead or lead-containing materials are not used in Geon Resin Id EP. Furthermore, no lead equipment is used. Stainless steel equipment is used in the manufacture of Geon Resin Id EP. Any microscopic traces of lead in Geon Resir 101 EP can come only through contamination. The following data indicates the lead analysis on 23 samples of Geon Resin Id EP, as determined by Spectro-Chemical Research Laboratories, Incorporated, 3313 West Lawrence Avenue, Chicago, Illinois.
