Survivor® Tyvek Expansion Mailers - Self-Seal Envelopes - 10x13x1.5 - White - 100/Carton

These 10" x 13" x 1-1/2" expansion envelopes are designed to expand 1-1/2" to provide lightweight, cost-efficient shipping for bulky items. Made from 14 lb. DuPont Tyvek material, these envelopes resist punctures, tears, and moisture, ensuring your contents stay protected during transit. They are half the weight of heavy-duty paper envelopes, helping you save on postage with each mailing.

The tough, expandable design of these envelopes resists overstuffing, bad weather, and rough handling, guaranteeing that your items arrive intact. The Redi-Strip closure makes sealing these envelopes a breeze - simply peel and press for an instant seal. Additionally, the Redi-Strip feature provides peace of mind by addressing concerns about surface germs in the workplace.

Save time and reduce waste with every mailing using these envelopes. The peelable strip protects the adhesive from dust, ensuring a longer shelf life in storage. These large envelopes are versatile mailers suitable for a variety of thick enclosures, from paper to textiles. They open wide to accommodate binders, books, manuscripts, transcripts, and more.
