These 9 1/2 x 12 1/2 inch flat Tyvek® envelopes are constructed from 14 lb spunbonded olefin, delivering puncture, tear, and moisture resistance that standard paper envelopes cannot match. The self-seal adhesive strip creates a secure, tamper-evident closure without moisture activation or additional tape, supporting fast throughput in high-volume mailing environments.
The white exterior keeps contents concealed and projects a clean, professional appearance suited to business correspondence, legal document distribution, marketing insert programs, and photo fulfillment. The interior footprint fits standard letter-size and legal-size documents flat, along with catalogs, promotional materials, and photos that must arrive undamaged.
Fabricated from DuPont™ Tyvek® spunbonded olefin, these envelopes resist the flex fatigue and edge damage common in transit handling. Each case contains 100 envelopes and ships via parcel carrier, making it practical to replenish inventory in quantities aligned to your mailing volume.
