These 9 x 12 x 2" white expandable Tyvek® envelopes are built from 18 lb. olefin — a synthetic material that resists puncture, tearing, and moisture at a level paper envelopes cannot match. The 2-inch gusset allows the envelope to expand around thicker contents while maintaining a clean, sealed profile throughout transit.
The expandable format suits documents, soft goods, product samples, kitted parts, and multi-item orders. E-commerce fulfillment centers, healthcare distributors, and retail replenishment operations all benefit from the combination of flexible capacity and reliable protection for lightweight but damage-sensitive shipments.
Each envelope closes with a self-seal adhesive strip — no tape, heat, or equipment required. The white exterior accepts standard shipping labels without surface preparation. Cases contain 100 envelopes and ship via parcel carrier.
