These 14 1/4 x 20 inch white self-seal padded mailers are a #7-size protective mailer built around interior fiber padding that expands during transit to absorb impact and shield contents from shock damage — eliminating the need for additional void fill or cushioning materials.

End flaps coated with natural rubber adhesive bond on contact without water activation or tape, delivering a secure close that holds through the full shipping process. The outer shell resists both moisture and puncture, providing a reliable barrier against handling abuse and environmental exposure in transit.

Sold in cases of 25 and parcel-friendly, these mailers are practical for e-commerce operations, retail distribution centers, and fulfillment facilities shipping flat or semi-rigid items such as apparel, documents, photos, and lightweight media on a regular basis.
