Common questions
Are these Tyvek® envelopes USPS and FedEx compliant?
Yes. These self-seal flat mailers meet USPS First Class Mail standards and are approved for FedEx and UPS shipping. Available with optional First Class printed borders for carrier recognition.
How much stronger are Tyvek® envelopes compared to paper?
14 lb. olefin Tyvek® material is 10 times stronger than standard paper envelopes. This tear and puncture resistance significantly reduces damage claims and returns.
Can these envelopes be used for moisture-sensitive items?
Absolutely. Tyvek® provides excellent moisture barrier properties, protecting documents and sensitive materials from water damage during transit and storage.
Do I need tape with the self-seal closure?
No. The pre-applied Redi-Strip adhesive eliminates tape requirements, saving labor time and reducing packaging material costs while ensuring secure, professional closures.
