Common questions
Are these mailers UPS and USPS compliant for flat-rate shipping?
Yes. At 8.5" x 14.5", these mailers are USPS Priority Mail compliant and can be used for UPS Ground and USPS services. Always verify dimensional weight pricing with your carrier.
What level of shock protection does 3/16" bubble provide?
3/16" bubble offers robust cushioning suitable for most fragile items including electronics, small glassware, and lightweight ceramics. For extremely heavy or delicate items, consider using additional internal padding.
How secure is the peel-and-seal closure against tampering?
The self-adhesive closure creates a tamper-evident seal that shows obvious signs of opening. Once sealed, the mailer cannot be reopened without visible damage, providing security assurance for e-commerce customers.
Can these mailers withstand moisture during shipping?
Yes. The 2 mil polyethylene exterior is moisture-resistant and protects contents from rain, humidity, and spills. However, they are not waterproof, for submersion protection, use additional waterproof barriers.
