Common questions
Are these envelopes USPS First Class Mail compliant?
Yes. The 10 x 13 x 1 1/2" dimensions meet USPS First Class Mail specifications for padded mailers, reducing postage costs compared to Priority Mail and ensuring on-time delivery for lightweight shipments.
How much stronger is Tyvek® than paper mailers?
Tyvek® 18 lb. olefin is 10 times stronger than paper envelopes in tear and puncture resistance. This durability reduces damage claims, customer returns, and replacement costs across your shipping operations.
Do I need additional tape or adhesive with the self-seal closure?
No. The integrated Redi-Strip self-seal closure provides secure, tamper-evident sealing without tape, glue, or additional labor. Simply peel and press for fast, consistent closure every time.
What items fit in the 1 1/2 inch expandable cavity?
The expandable sidewalls accommodate documents up to 1/2 inch, padded samples, small circuit boards, fabric swatches, jewelry, photos, and soft components up to the 1 1/2 inch depth, eliminating the need for rigid boxes and reducing dimensional weight charges.
