These 10 x 13 inch Tamper Evident Tyvek® Envelopes are built from 14 lb spunbonded olefin — the same DuPont Tyvek® material used in demanding protective applications — delivering puncture, tear, and moisture resistance that standard paper mailers cannot match. The result is a mailer that protects contents through the full handling cycle without adding significant weight.
The tamper-evident closure sets these apart for sensitive shipments: once the seal is broken, the word "OPENED" appears permanently in red on the flap, creating an irreversible indicator of tampering. This makes them a dependable choice for healthcare distribution, legal and financial document handling, chain-of-custody fulfillment, and any program where recipient accountability must be documented.
The interior accommodates letter-size documents, flat media, and protective inserts with room to spare. Each case contains 100 envelopes and ships via parcel carrier.
