14 1/2 x 18 1/2 Envelopes

JAM Paper bubble mailers in this size use 80 lb kraft exteriors with built-in padding and peel & seal closures, adding cushioning for merchandise, documents, accessories, samples, and other lightweight items that need more protection than a standard envelope. These bubble mailers are available in white and brown kraft.

Bubble lining helps absorb minor impact and surface contact during handling, while the kraft exterior provides a sturdy mailing surface for labels and shipping information. Peel & seal closures make package preparation faster and help keep contents contained through delivery. The lightweight padded design is useful for offices, retailers, online sellers, fulfillment teams, and personal shipping.

Oversized bubble mailers work well for small products, accessories, promotional items, documents, gifts, and ecommerce orders. Kraft padded envelopes give businesses a practical option for protective shipping without moving to a box for every order. The combination of cushioning, kraft paper, and self-sealing closure supports efficient packing and reliable presentation.
