Common questions
Do I need tape or additional adhesive to seal these mailers?
No. The integrated peel-and-seal closure provides a complete, tamper-evident seal without tape, glue, or stiffeners. Simply peel back the strip and press to seal, use for fast-paced fulfillment operations.
Will these mailers work with standard postage and shipping carrier automation?
Yes. These mailers are designed to meet USPS, UPS, and FedEx specifications for flat mail processing. The.012 chipboard construction provides the rigidity needed for automated sorting without additional preparation.
How much postage can I save compared to padded alternatives?
The lightweight chipboard construction weighs significantly less than padded or bubble-lined mailers, reducing dimensional weight charges. For high-volume shippers, the cumulative postage savings translate to substantial quarterly cost reductions.
Can I load documents from the side like a traditional envelope?
Yes. The side-loading design allows you to insert and retrieve documents without tilting or forcing items through a top opening. This speeds up packing, reduces product damage, and improves the unboxing experience for recipients.
