Common questions
Are these mailers UPS/FedEx approved?
Yes. The 8" 4" dimensions meet USPS Priority Mail, UPS Ground, and FedEx standard envelope specifications. The self-sealed closure is carrier-compliant. Verify weight limits with your carrier (typically <1 lb for dimensional rate optimization).
What is the bubble cell size and how much shock protection does it provide?
The 3/16" bubble lining offers medium-duty cushioning, ideal for non-fragile or semi-fragile items (jewelry, small electronics, documents). For extremely fragile goods, consider our larger bubble or multi-layer options.
Can I use these for heavy or sharp items?
No. These mailers are designed for lightweight, non-sharp items under 1 lb. Heavy goods or items with sharp edges require rigid boxes. The kraft exterior provides tear resistance but is not puncture-proof.
Is the kraft exterior printable for branding?
Yes. The smooth recycled kraft surface accepts custom printing (flexo, digital, or pre-printed labels). Contact sales for volume print specifications and turnaround times.
