Value Brand Expansion Poly Mailers 11x13x2 White PK100

11 x 13 inch expansion mailers for high-volume

These white poly mailers measure 11 inches by 13 inches with a 2 inch expansion gusset, providing extra depth for bulky items such as clothing or boxed goods. The pack contains 100 units, making it suitable for businesses that dispatch large quantities of orders daily. The self-sealing closure speeds up packing workflows without the need for tape or heat equipment. A built-in tear strip allows recipients to open the package cleanly without damaging the contents.

Thin 0.003 inch poly construction keeps weight

The mailers use a lightweight poly material just 0.003 inches thick, which adds minimal mass to shipments and helps control dimensional-weight pricing. Because the film is flexible and non-rigid, it conforms to irregular shapes and reduces the risk of corner damage during transit. The smooth white surface accepts handwritten labels or printed shipping stickers without smudging. No pre-printed address lines are present, so the full face is available for custom branding or carrier barcodes.

Self-seal adhesive and tear strip simplify

Each mailer features a permanent self-sealing strip that creates a tamper-evident bond once pressed, eliminating the expense and time of separate tape rolls. The integrated tear strip runs along the opening edge, giving end users a controlled way to access contents without scissors or knives. These two features together reduce packing labour and improve the unboxing experience for customers. The pack of 100 units arrives ready to use with no additional accessories or software required.
