Common questions
Are these mailers UPS and FedEx approved?
Yes. The 3/16" bubble lining meets carrier requirements for proper cushioning, and the #4 size is recognized across all major shipping platforms. The white paper exterior and self-seal design comply with standard mailability regulations.
How much bubble coverage do I get per mailer?
Each mailer features 3/16" high slip-bubble lining that provides full perimeter protection. This thickness is engineered to absorb moderate shock while keeping mailer weight low, critical for controlling dimensional weight charges on platforms like UPS.
Can I reuse these mailers or are they single-use?
These are designed as single-use mailers. Once the peel-and-stick strip is applied and sealed, the tamper-evident closure cannot be reliably reused. For cost optimization, buy in bulk (cases of 100) to reduce per-unit cost on high-volume shipments.
What products should I avoid shipping in these mailers?
Avoid heavy items (over 5 lbs), extremely fragile glassware without secondary packaging, or items requiring climate control. For those scenarios, upgrade to thicker bubble mailers or corrugated boxes. The #4 size works best for lightweight, moderately delicate goods.
