Mailers & Envelopes

SELECTION EXPERT ADVICE

Rigid vs Flexible Mailers
MORE INFO
Corrugated mailer boxes provide structure and protection for items that cannot be bent or compressed in transit. Poly and padded mailers work well for soft goods, clothing, and flexible items where keeping the shipment lightweight is the primary cost driver.
Built-In Protection Levels
MORE INFO
Bubble-lined mailers add a cushioning layer for fragile or delicate items without requiring additional packing materials inside the package. For documents and flat goods that do not need padding, flat and paper mailers are the more cost-effective choice.
Closure Type and Packing Speed
MORE INFO
Peel-and-seal closures reduce packing time significantly on high-volume fulfillment lines. For operations processing hundreds of orders per shift, the closure method on your mailer has a real cumulative impact on throughput and labor cost over the course of a workday.

Buying path

Buy Mailers & Envelopes by the specs that change the order

Use filters, product titles, and product pages to compare size, material, pack count, case quantity, and fit before ordering.

Compare

Use filters and product titles to narrow by the specs that affect fit.

Confirm

Open the product page before ordering a case so you can check quantity, unit, and limits.

Reorder

Save the SKU or product link for repeat purchasing and support questions.

Larger orders

For pallet, recurring, or mixed-SKU needs, send support the details before placing a large order.

What to check first

  • Usable inside size
  • Padding or material
  • Closure type
  • Case quantity
Common wrong-order risk: Forgetting item thickness. A mailer that fits flat dimensions can still be too tight once the product is packed.
