Can Tyvek® envelopes be used on automatic insertion and addressing/barcoding equipment? Will they need any special equipment for either of these processes?

DuPont™ Tyvek® Envelopes run smoothly and efficiently on most standard automatic envelope insertion and inkjet addressing equipment.

Automatic Insertion
Tyvek® envelopes are readily processed on most standard inserters made by major manufacturers. The secret to a smooth insertion process, just as with other envelopes, is using an envelope that meets the design requirements of the equipment manufacturer. Key design parameters are flap dimensions, flap taper, throat design and enclosure clearance.
Envelope types should be an open-side booklet or diagonal seam, both with remoistenable gum.

Many envelope users don't realize that automatic insertion of Tyvek® envelopes can speed up their process. If your customers are hand inserting Tyvek® envelopes with pressure-sensitive closures, they could eliminate a very time-intensive process by switching to automatic insertion and water-activated gum closures. Ask your Tyvek® envelope manufacturer for further information.

Inkjet Addressing/Barcoding
Tyvek® envelopes are compatible with most inkjet addressing/barcoding systems. In fact, a wide variety of oil- and solvent-based inks provide high-performance inkjet addressing/barcoding on Tyvek® envelopes. For companies using water-based inks, minor line adaptations will provide satisfactory results on most systems.

Some of these modifications may include draft-mode printing, which requires less ink; extended feed intervals, which provide more time for the ink to dry; supplemental driers; and extended exit.
