Zoro Select B833 Bubble Lined Poly Mailers 8 1/2 x 12 in White PK100

Ready-to-Ship Mailers for High-Volume Fulfillment

The Zoro Select B833 bubble-lined poly mailers arrive in a pack of 100, giving e-commerce teams a ready supply of self-sealing white envelopes. Each mailer measures 8 1/2 by 12 inches on the outside with an 8 7/8 by 10 3/4 inch usable area, sized for documents, apparel or small accessories. The 3/16 inch bubble lining cushions contents without adding bulk, and the peel-and-seal closure secures shipments without tape. No tear strip or pre-printed address lines keep the exterior clean for custom labels.

Consistent Protection Across Repeated Packing Cycles

The 0.188 inch material thickness maintains its cushioning feel whether you pack ten orders or the full hundred in a single shift. Bubble cells retain air through repeated handling, so the fiftieth parcel receives the same impact resistance as the first. Self-sealing adhesive stays tacky in typical warehouse temperatures, eliminating the need to re-press or reinforce flaps during busy periods. White poly surface resists scuffs and moisture, keeping barcodes readable from pickup to delivery.

Fixed Usable Dimensions Define What Fits

The 8 7/8 by 10 3/4 inch internal space is the single specification that determines whether your product ships without folding or crushing. Items larger than this footprint require a bigger mailer; smaller items may shift unless you add void fill. Pack quantity of 100 suits operations that process steady daily volume but may exceed the needs of occasional shippers.
