ABSTRACT:
Alcoholyzed ethylene-vinyl acetate resins and unplasticized, thermoplastic packaging films constituted thereof which are suitable as food wraps, particularly for the packaging of fresh red meat. The alcoholyzed resin is prepared from an ethylene-vinyl acetate copolymer containing from about 9 to 45 weight percent combined vinyl acetate and having a melt index of from about 0.1 to 70 g/10 min., the alcoholyzed resin containing from about 5 to 20 weight percent residual vinyl acetate and having a melt index of from about 0.1 to 100 g/10 min. Preferred films prepared from these alcoholyzed resins exhibit oxygen transmission rates in excess of about 350 cc/100 sq.in./24 hr./atm. at 23.degree. C, carbon dioxide transmission rates in excess of about 1000 cc/100 sq.in/24 hr./atm. at 23.degree. C, and moisture vapor transmission rates of from about 10 to 50 g/100 sq.in./24 hr. at 100.degree. F and 90% relative humidity (R.H.), essential characteristics of the thermoplastic films for wrapping cuts of fresh red meat.
