What the AI looks for in Business Mailing Envelopes

Size
#10 (4-1/8 x 9-1/2 in) for a letter-size sheet folded in thirds; #9 (3-7/8 x 8-7/8 in) is the usual return envelope enclosed inside a #10 These are the standard sizes that fit folded letter paper and nest correctly for reply mail.
Security tint
Choose an inside tint pattern for checks, statements or personal data The tint stops the contents being read through the paper.
Window alignment
A standard #10 window sits at the lower left; confirm that your template prints the address inside it A misaligned address gets cut off and the mail can be returned.
Seal type vs volume
Self-seal or peel-and-seal for hand sealing; gummed for mail machines Machines need gummed flaps, while hand sealing gummed flaps at volume is slow.
Paper weight
About 24 lb white wove is the business standard Lighter stock feels flimsy and can show the contents through.

Questions

What is the difference between self-seal and peel-and-seal?

Self-seal has latex on both the flap and the body and seals when pressed together; peel-and-seal has a release strip you remove first, which holds better in humid storage.
