T c writer attended subject meeting to audit conferences on ? plastics, particularly tne two syizpojj^ on Plastics n Packaging; anot .er > nip of papers on Plastics in Agriculture was also attended. Reviews of these sessions are attached. 2. i_s quite obvious -3- ail areas of t.^e plastics industry growing rapidly and ar:e a promising future for same yuan n ccue. Whereas all . .anefaccuring is expected to grow afi. flat- -;eraye annual rate of 4.17. for the next ten years, plastic* wrowt is expected j average 15.1Z. The dollar value of 7 las tics in packaging 1j expected to double by 1970 to about rl.^ billion; fILl-S arc c.-.e largest single cutlet. 3. T e paper of greatest interest - "FDA Status of PVC Compounds" added little to t..e writer's knowledge in this area; it did ndicate that presently available stabilizers acceptable to FDA ptc- adequate for present purposes (processing temperatures of 3^C-j30*F) and will preserve physical c;aracteristics of PVC lor brief tin at 4u0I. liscoloration is not prevented at t: is temperature. He jjjc.cz could be aace on date of promulgation if FDA regulation perszUtiag dialkyl tin stabilizers. 4 From the point of view of the writer all papers were well presented in that uses were well covered and good attempts :^ade to sstbpM jment and future markets.
