Abstract

There is disclosed a method of selectively increasing the hydrophilicity of a web, such as a plastic glucose electrochemical test strip. The web is corona arc treated, and a film of water is selectively applied to the web where a reduction of the effect of the initial corona treatment is desired. The water is then removed by drying.
