Expandable Self-Seal Envelopes 10x13

These envelopes measure 10 by 13 inches with a 2 inch expansion depth. They use a self-seal closure that requires no moisture or tape. The pack contains 100 kraft envelopes suited for shipping documents or bulky items.

Self-Seal Closure Limits

The adhesive strip bonds when the two flaps are pressed together. It is designed for single use and cannot be resealed once opened. Extreme heat or humidity may reduce adhesion reliability over time.

Capacity and Headroom

The 2 inch gusset accommodates thick catalogues, samples or multiple file folders. Standard flat mail fits easily but the envelope will not hold rigid objects thicker than the expansion depth. Overstuffing beyond the gusset limit risks seam failure.
