These #4 kraft self-seal padded mailers measure 9 1/2 x 14 1/2 inches and deliver built-in protection without requiring additional void fill. An internal fiber padding layer absorbs impact during handling and transit, while the moisture-resistant, puncture-resistant kraft outer shell guards contents against environmental exposure and rough handling.

The peel-and-seal closure uses a natural rubber adhesive that bonds to itself without water or heat activation, producing a tamper-resistant seal once closed. This makes them well-suited for e-commerce fulfillment, direct mail campaigns, retail distribution, and photo or document shipments where a secure, tool-free closure is a priority.

Each mailer is parcel-friendly and sold in packs of 25, making them practical for lower-volume shipping operations or supplemental stock alongside larger case quantities. Interior dimensions accommodate standard #4 size flat goods, literature, and lightweight packaged products.
