Heavy Duty Mailing Envelopes

Heavy Duty Mailing Envelopes – Open Side Mailers

Choose these heavy-duty 32# tan/brown kraft envelopes when your documents must be protected at all costs. Designed for multipurpose use, they offer an attractive vellum finish that looks professional. There is no window to protect envelope content privacy, and a large flap with an open side offers style and superior function. You can order these USA made envelopes in quantities suitable for your mailing projects.

Maximum Protection

Ramp up the level of protection you get from a mailing envelope with 32# kraft envelopes made from sturdy Roptex. With its large 10” x 13” measurements, there’s room inside this windowless envelope for storing reports, brochures, manuscripts, photos, and other documents. The vellum finish provides a nice feel to the touch for those doing the mailing and for recipients.

Wide Flap with Remoistening Seal

The open side offers a wide flap that also serves as part of the strong envelope wall. A remoistening seal helps keep contents secure during the mailing process.
