Common questions
Are these mailers UPS and FedEx compliant?
Yes. The 12" x 8.5" #2 size meets USPS, UPS, and FedEx dimensional weight requirements for cost-effective shipping. Always verify current carrier specifications for your specific service level.
What's the difference between heat-seal and standard mailers?
Heat-seal mailers feature a thermoplastic adhesive strip that bonds permanently when heated, creating a tamper-evident, secure closure. They're ideal for high-value items or brands requiring enhanced security compared to traditional peel-and-seal.
How much shock protection does the 3/16" bubble provide?
The 3/16" bubble lining offers adequate cushioning for lightweight fragile items like electronics, cosmetics, and jewelry during standard parcel handling. For heavier items or extreme fragility, consider pairing with additional void fill.
Can I recycle or compost these mailers?
The kraft paper exterior is fully recyclable. The bubble lining is polyethylene plastic and should be separated before recycling the paper component, or disposed of according to local plastic guidelines.
