Claims

1. A COMPOSITION CONSISTING ESSENTIALLY OF (1) A DERIVATIVE OF AN AMYLACEOUS MATERIAL SELECTED FROM THE GROUP CONSISTING OF AMYLACEOUS (A) ETHERS, (B) ESTERS, (C) MIXED ETHER-ESTERS, (D) MIXED ETHERS AND (E) ANY COMBINATION OF (A), (B), (C), AND (D), (2) A PLASTICIZER FOR SAID DERIVATIVE, AND (3) WATER, THE AMOUNT OF WATER BEING 1%-20% BY WEIGHT OF SAID DERIVATIVE ON A BONEDRY BASIS, THE AMOUNT OF PLASTICIZER BEING AT LEAST ABOUT 3% BY WEIGHT OF SAID DERIVATIVE, SAID PLASTICIZER BEING SELECTED FROM THE GROUP CONSISTING OF WATER-SOLUBLE AND WATER-MISCIBLE PLASTICIZERS, SAID COMPOSITION BEING FURTHER CHARACTERIZED BY BEING WATER-SOLUBLE AND BY FLOWING UNDER HEAT AND PRESSURE TO FORM ARTICLES WHICH ARE HEAT-SEALABLE.
