2up W-2 Double Window Envelope (Self Seal & Tamper Evident)

Tamper-evident closure for standard 2-up W-2 mailings

DWENVSTE pairs a self-seal flap with tamper-evident cuts, so it fits any traditional 2-up W-2 recipient form while giving payroll staff proof an envelope wasn’t reopened after sealing. Both windows are tinted and cellophane-glazed to keep names, addresses and wage figures covered in transit.

To close, simply press the flap down — no moisture pad needed. Because the envelope ships open, you can fold and stuff a full batch of statements before sealing any of them. If the flap is later pried open, the tamper-evident cuts tear visibly, flagging the attempt.

Payroll and HR teams that mail sensitive wage statements often prefer this closure over a plain self-seal flap, since it gives the recipient a visible signal if the envelope was opened before it reached them. It fits the same 2-up W-2 recipient forms as the standard self-seal and moisture-seal versions, so no change in printed form is needed to switch to it.
