White bubble lined poly mailers combine a puncture-resistant poly outer shell with a 5/16" bubble lining, delivering substantially more cushioning and abrasion resistance than standard single-ply poly mailers of comparable size.

The 9 1/2 x 14 1/2 inch interior accommodates documents, soft goods, apparel, flat merchandise, and lightweight packaged products — making these mailers a practical choice for e-commerce fulfillment, retail distribution, subscription box operations, and catalog-order shipping.

Each mailer features a peel-and-seal strip that creates a tamper-evident closure without tape or additional supplies. The lightweight poly construction keeps package weight low relative to equivalent corrugated alternatives. Sold in cases of 50 mailers.
