Common questions
Are these mailers UPS and USPS compliant?
Yes. The 9.5" x 14.5" size qualifies as USPS Priority Mail #4 and fits standard UPS ground shipping dimensions, making them ideal for multi-carrier fulfillment operations without surcharges.
What level of shock protection does the 3/16" bubble provide?
The 3/16" high-slip bubble lining provides adequate cushioning for lightweight fragile items (electronics under 1 lb, cosmetics, jewelry). For heavier or extremely fragile goods, consider pairing with foam inserts or upgrading to thicker bubble mailers.
Can I apply a shipping label directly to the white exterior?
Yes. The smooth white paper exterior accepts thermal and inkjet labels without issues. The peel-and-stick closure keeps the label area clean and unobstructed for optimal barcode scanning.
What's the coverage cost per mailer in bulk?
At 25 mailers per case, you get per-unit economy pricing versus individual purchases. These self-seal mailers eliminate tape waste, reducing fulfillment labor and material costs compared to traditional padded envelopes.
