Mail-Well Inc. introduced a new safety-window envelope, the Visulope. The new product is in response to numerous customer inquiries for envelope products that consumers will feel more secure in opening. The Visulope is designed to allow the visual detection of unusual substances within an envelope by allowing mail handlers and recipients to look through windows that wrap around the bottom of the envelope. In addition to putting into immediate production the Visulope envelope and beginning production of a separate line of safety-oriented products, called Tamper-Evident Envelopes, Mail-Well is also looking into incorporating existing biological technologies into new envelope products, including the Contamination Alert Envelope and the Antibacterial Envelope.
