Durable Tyvek expansion mailers

Quality Park R4202 envelopes use DuPont Tyvek to protect bulky documents and items that are not too heavy. The material resists rips, tears and punctures while remaining water-resistant and moisture-resistant. Each mailer replaces costly boxes or cartons for everyday shipping needs.

Flap-Stik peel-and-seal closure

The open-end design features a convenient Flap-Stik strip for fast sealing without tape or moisture. Simply peel the liner and press to close, saving time in busy mailrooms. White colour gives a clean, professional appearance for business correspondence.

25-count box for regular-weight loads

A box of 25 envelopes suits offices that mail moderate volumes of expanded contents. Tyvek strength handles typical document bundles but is not rated for heavy or sharp-edged loads. Buyers needing higher capacity or reinforced seams should consider heavy-duty alternatives.

Questions about this item

How do I seal the 10 x 13 Tyvek envelope using the Flap-Stik closure?

Peel the protective strip from the flap, press the adhesive firmly along the entire length, and hold for a few seconds to activate the bond.

Will the DuPont Tyvek material degrade if the envelopes are stored for a long time?

Tyvek resists moisture and does not become brittle under normal indoor storage, so the envelopes remain usable for years.

At what point does the 1 1/2 inch expansion gusset reach its limit when packing bulky documents?

The gusset expands to 1 1/2 inches; overfilling beyond that depth stresses the seams and prevents the Flap-Stik from sealing securely.
