Description

These self-seal expandable Tyvek® envelopes measure 12 x 16 x 2" and are constructed from 18 lb. olefin material — the same spunbonded polyolefin used in DuPont Tyvek® products. That construction delivers puncture, tear, and moisture resistance that standard paper envelopes cannot match, while the peel-and-strip adhesive closure eliminates the need for tape or sealing equipment.

The 2-inch gusset accommodates documents, catalogs, soft goods, product samples, and other moderately thick contents without compromising envelope-style handling. These envelopes are rated for First Class mail compatibility, making them practical for publishers, retailers, healthcare distributors, and direct-mail operations that need a durable, postage-eligible format for outgoing shipments.

Envelopes are sold in cases of 100. Interior dimensions are 16" L x 12" W with a 2" expandable gusset depth. Cases ship via parcel carrier.
