Quality Park Advantage Flap Stik Tyvek Mailer 9 x 12 White 100/Box office furniture

Durable Tyvek Mailers for Document Shipping

Quality Park Advantage Flap Stik Tyvek Mailers use 14 lb DuPont Tyvek material that resists punctures, tears and moisture. The lightweight construction helps reduce shipping costs while protecting contents. Each white envelope measures 9 x 12 inches and includes a tamper indicating panel that reveals "OPENED" in red if the seal is broken. Sold in boxes of 100 for high-volume mailing needs.

Verify Envelope Dimensions and Closure Type

Confirm that the 9 x 12 inch size fits your documents without folding. The Flap-Stik self-adhesive closure requires no moisture to seal, so ensure your packing process accommodates this method. Check that the tamper evident feature meets your security requirements for sensitive shipments. The white surface accepts standard labels and postage.

Integrates Into Mailroom Workflows

These mailers replace traditional paper envelopes for heavy or valuable items that need extra durability. The self-sealing flap speeds up packing lines by eliminating tape or water-activated glue. Tamper evidence provides a visible security layer for confidential documents. The lightweight Tyvek material keeps dimensional weight charges low for carriers. Buyers needing padded cushioning or bubble lining should consider alternative mailers.
