Kraft Corrugated Mailers: Sizes, Bundles and Closures

Choose a kraft corrugated mailer by your packed item’s dimensions, the closure you need and the number of mailers in each bundle. Compare eight sizes below, then check the exact product’s current price and availability.

Fold-and-tuck is not an adhesive sealing strip. ML883K is a fold-and-tuck mailer. If your order requires peel-and-seal adhesive, confirm that feature on the exact product before buying. A historical “self-seal” URL does not establish an adhesive closure.

All eight original products below are sold in bundles of 50. Dimensions are listed length × width × depth; check the product’s dimension convention and usable space before ordering. Prices are linked directly to the live products rather than copied into this guide.

Plan quantities for six other mailer sizes

The Mailer Order Planner covers six additional kraft corrugated sizes, including 12 × 9 × 2 and 12 × 9 × 4 inches. Choose a size, follow the quantity prompt and review the bundle count, total mailers and current pricing before adding to cart. ML883K is not one of those six sizes; use its exact product and shipping links above for the 8 × 8 × 3 inch option.

Before placing your order

1. Measure the packed item. Include cushioning, inserts and any protruding parts. A close nominal dimension alone does not establish fit.
2. Check the closure. A tuck flap and a peel-and-seal adhesive strip are different features. Confirm the exact assembly and sealing method for your SKU.
3. Count bundles, not individual mailers. For these eight products, order 1 bundle for 50 mailers, 2 for 100 or 5 for 250.
4. Compare the delivered total. Product subtotal, shipping and tax are separate. Use a destination-specific estimate for ML883K, or request a quote for a larger or mixed order.

Common buying questions

Is the 8 × 8 × 3 mailer self-sealing?

The original ML883K listing specifies fold-and-tuck corrugated construction. Do not treat that as a promise of peel-and-stick adhesive. Check the exact product if adhesive closure is required.

Can I buy a single mailer?

These eight listings are sold in bundles of 50, not individually. A product quantity of 1 means one complete bundle.

Is shipping included in the displayed product price?

Do not assume it is included. The ML883K estimator shows product subtotal and ZIP-based shipping separately. The final delivery address and cart determine checkout charges.

What if none of these sizes fits?

Use the Mailer Size Chart, browse mailer boxes, or compare the six sizes in the Planner. For larger quantities or mixed SKUs, request a bulk quote.
