Common questions
What is the bubble cell size and coverage?
These mailers feature 3/16" high slip bubble cells that provide optimal shock absorption for lightweight to moderately fragile items. The bubble lining covers the interior surface to distribute impact force and protect contents during standard shipping conditions.
Are these mailers UPS and FedEx compliant?
Yes. The kraft paper construction and heat-seal closure meet carrier requirements for domestic and international shipping. Heat-sealed seams create secure, uniform closures that pass carrier inspections without additional tape.
Can I heat seal, tape, or staple these mailers?
Absolutely. The kraft paper exterior accepts all three closure methods. Heat sealing is fastest for high-volume operations, while taping and stapling offer flexibility for lower volumes or mixed operations.
How much weight can these mailers protect?
The 3/16" bubble lining effectively protects items up to approximately 5-8 pounds depending on fragility. For heavier or more delicate goods, consider upgrading to a larger size or thicker bubble specification. The kraft exterior and bubble cushioning work together to provide shock resistance.
