Common questions

What makes Tyvek® envelopes better than standard paper mailers?
Tyvek® olefin is 10 times stronger than paper, providing resistance to punctures, tears, and moisture. This reduces product damage, insurance claims, and shipping delays, lowering your total cost of ownership despite slightly higher unit cost.
Are these envelopes USPS and UPS compliant?
Yes. Tyvek® envelopes meet USPS, UPS, FedEx, and international postal standards. The self-seal closure is recognized by all major carriers as a secure, compliant sealing method.
Can the green color impact my branding or tracking?
The vibrant green actually enhances visibility in sorting facilities and reduces misrouted packages. Many customers use colored Tyvek® mailers as a branding touchpoint that differentiates premium shipments and improves customer unboxing experience.
How does the self-seal closure work, and do I need additional materials?
Simply insert contents, pull back the Redi-Strip tab, and press the adhesive flap sealed. No tape, glue, or additional supplies needed. This saves labor time and eliminates over-sealing that delays mail processing.
