Abstract
Method of making a multilayer protective covering such as a surgical glove, finger cot or condom. Mold with a first layer is dipped into a gas-releasing solution which comprises a release agent, a blowing agent, and/or a coagulant. The mold is then dipped into a layer-forming solution to form a second layer. Heat is applied and gas forms between the layers, separating the layers. An antimicrobial solution may replace gas between the layers.
