Double-window business envelopes

These No. 8-5/8 envelopes feature two poly windows that show both the return and mailing addresses at once. A 24 lb white stock with an inside tint keeps document contents private. The self-sealing closure needs no moisture and a unique double-flap design prevents premature sticking. Each box contains 500 envelopes ready for high-volume mailing.

Suited for bulk cheque and statement runs

Offices that process large batches of payments or statements benefit from the double-window layout and fast peel-and-seal action. The tinted interior adds confidentiality for sensitive financial documents. Organisations that need single-window formats, coloured stock or non-adhesive closures should look at other envelope styles.

Self-seal double-flap closure

The lower flap lifts away and the envelope seals with pressure alone, eliminating the need for moistening or separate adhesive. This mechanism also keeps the gum from activating during storage. Buyers who require a traditional gummed flap or a different sealing method will need an alternative product.

Questions about this item

How do you seal the self-sealing double-flap envelopes without getting the gum stuck prematurely?

Raise the lower flap first, then press the upper flap down to activate the adhesive without moisture.

When will the box of 500 envelopes need to be replaced?

After all 500 envelopes are used; each envelope is single-use and not refillable.

What weight limit applies if you stuff multiple pages into the 24 lb envelopes?

The 24 lb paper stock supports typical business correspondence; overstuffing may prevent a clean seal.
