Common questions
Will these mailers protect against bending and creasing?

How do the peel-and-seal closures perform in high-volume operations?
The self-adhesive seal is engineered for reliability and consistency across high-volume packing. The pull-tab tear strip enables customers to open mailers cleanly without damaging contents, enhancing unboxing experience.
Can I reduce postage costs by using these mailers?
Absolutely. The lightweight.028 kraft chipboard keeps per-unit weight low, reducing dimensional and actual postage rates compared to heavier alternatives while maintaining full puncture and bend protection.
