Common questions
What's the difference between 3/16" bubble and other cell sizes?
3/16" bubble provides an optimal balance of cushioning and lightweight design. It absorbs shock from drops and impacts while keeping mailer weight low, critical for keeping postage and UPS Ground rates down. Larger bubbles offer less protection per square inch; smaller bubbles add unnecessary weight.
Are these mailers UPS and USPS eligible?
Yes. The white self-seal design meets USPS Priority Mail and flat-rate eligibility standards. The lightweight paper exterior keeps dimensional weight minimal, reducing UPS Ground surcharges. Confirm size limits with your carrier for your specific service.
How much coverage does one case provide?
One case of 25 mailers covers 25 individual shipments. For high-volume operations, calculate monthly usage and order in multiples, bulk orders often qualify for volume discounts.
Can I use these for branded shipping without adding labels?
The white paper exterior accepts printed labels, barcodes, and branded messaging without additional cost. Many e-commerce businesses print directly onto white mailers for a premium, cohesive unboxing experience.
