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.
