Abstract
A laminate and a coated web suitable for use as containers exhibiting a static decay of at least 90% in less than 2 seconds while measured at +/-5,000 volts, at 10% relative humidity and 24 hours conditioning is disclosed. The laminate and coated web comprise a paper substrate or a synthetic fiber substrate, a first coating on at least one surface of said paper substrate comprising synthetic hectorite clay and optionally a second coating comprising an organic or inorganic pigment applied over at least one of said coatings. These laminates are useful as antistatic coated paper containers.
