Common questions
Are these envelopes waterproof and moisture-resistant?
Yes. Tyvek® olefin material provides moisture and liquid protection, safeguarding contents from humidity, water damage, and environmental contaminants during shipping and storage.
Do these envelopes meet postal carrier requirements?
Yes. These self-seal flat Tyvek® envelopes comply with USPS, UPS, and FedEx shipping standards. Available in both plain and First Class printed border versions for carrier compliance.
How much stronger are these than paper mailers?
Tyvek® envelopes are ten times stronger than traditional paper envelopes. The 14 lb. olefin construction provides exceptional puncture and tear resistance, significantly reducing damage claims and product loss.
Can I use these for side-loading or flat-loading?
These are flat-loading envelopes with a single-flap design and self-seal closure. The 20" x 15" dimensions accommodate most documents, certificates, and smaller rigid items while maintaining a professional appearance.
