1 PROCESS ECONOMICS PROGRAM SRI INTERNATIONAL Abstract Process Economics Program Report No. 159A SPECIALTY PLASTIC FILMS (September 1988) Menlo Park, California This report covers the technologies and economics for the production of specialty plastic films. Investment and production costs are presented for manufacturing the following specialty films: Agricultural films--eva and PVC Microporous films--pp and PET Fluoropolymer films--fep and PFA a Polycarbonate film (PC) Polyimide film (PI). The report also reviews the current status of the plastic film industry. PEP 85 JJLM

3 I I For detailed marketing data and information, the reader is referred to one of the SRI programs specializing in marketing research. The Chemical Economics Handbook Program covers most major chemicals and chemical products produced in the United States and the World Petrochemicals Program covers major hydrocarbons and their derivatives on a worldwide basis. In addition, the SRI Directory of Chemical Procfucefs services provide detailed lists of chemical producers by company, product, and plant for the United States and Western Europe. I I
