Abstract

Development of biopolymer films and coatings from protein, polysaccharide, and lipid materials has received increased interest in recent years. In the midst of rising concerns over solid packaging waste and dwindling petroleum reserves, the renewable and degradable nature of biopolymer fiilm ingredients make such fiilms particularly appealing for innovative uses in the fiield of packaging. However, unlike some proteins, few nonfood applications for wheat gluten have been developed. In 1990 world wheat production was 589 million metric tonnes, of which 12.6% was produced in the US. Industrial Uses of Agricultural Materials (June, 1993) reported consolidated sales for low density polyethylene (LDPE) at about 3.1 million metric tonnes for various food and nonfood packaging uses in the US in 1992. The total LDPE sales, agricultural uses and trash bags sales accounted for 770,000 metric tonnes in 1992. A 30% market penetration of wheat gluten polymer in agricultural mulches and trash bags would use around 230,000 metric tonnes of gluten in the US alone.
