Common questions
Are these envelopes waterproof and moisture-resistant?
Yes. Tyvek® material is inherently waterproof and moisture-resistant, protecting contents from water damage, humidity, and environmental exposure during transit. This is critical for pharmaceutical, electronics, and document shipments.
How do the self-seal closures perform in high-volume operations?
The pressure-sensitive adhesive strip is pre-applied and requires only firm pressure to seal, no water or equipment needed. Users can seal 100+ envelopes per hour by hand, reducing labor costs compared to tape-sealed alternatives.
What is the weight capacity and how does this compare to paper mailers?
These 7 1/2" x 10 1/2" envelopes support documents and lightweight items up to several pounds. At 10x stronger than paper, they reduce damage claims and customer returns while meeting USPS size/weight specifications for First Class Mail.
Are these envelopes compliant with USPS and shipping carrier requirements?
Yes. Available in plain white or with First Class Mail printed borders for USPS compliance. The 7 1/2" x 10 1/2" dimension meets USPS flat-size requirements, reducing postage costs versus oversized alternatives.
