Eric Industries Inc., a plastic envelope manufacturer, has introduced Anthrax Evident Mailers, tamperproof plastic envelopes with windows that provide recipients with a view of enclosed contents before opening.
According to Eric, Dallas, the envelopes are sealed on three sides with a thermal seal. On the open end of the envelope, there is a barrier zipper lock and a tamper permanent adhesive with a release liner, which Eric said prevents dangerous contaminants from exiting or entering the envelope.
Some major users of Eric's plastic envelopes include the U.S. government, Pitney Bowes, Washington Mutual and Boeing Corp.
