These 10 1/2 x 16 inch #5 white self-seal padded mailers combine a moisture-resistant, puncture-resistant outer shell with interior fiber-fill cushioning that expands under handling pressure to absorb shock in transit. The peel-and-seal closure uses a natural rubber adhesive that bonds to itself, creating a tamper-resistant seal without tape or additional fasteners.

These mailers are well suited to e-commerce fulfillment, warehouse distribution, retail replenishment, and direct-to-consumer shipping operations. They accommodate flat or semi-rigid items — books, documents, photos, soft goods, and light electronics — that benefit from lightweight padding without added bulk or supplemental cushioning material.

The white exterior presents a clean, professional appearance appropriate for customer-facing shipments. Each case contains 25 mailers and ships via parcel carrier.
