Frequently Asked Questions
Are peel-and-seal envelopes secure enough for mailing greeting cards?
Yes. Modern peel-and-seal adhesives are designed to create a firm bond that holds through standard postal handling. For extra protection (very thick or textured cards), add a small strip of clear tape or use a rigid mailer inside the envelope if required.
What paper weight should I choose for greeting-card envelopes?
Aim for 80–95 lb. text-weight (about 120–160 GSM) for a premium feel and good protection. 95 lb. is sturdier and better for art cards; 80 lb. is still durable and often available in colored premium options.
Can I print addresses on these envelopes at home?
Most of the envelopes reviewed are labeled laser and inkjet compatible. Test one envelope on your printer first, and avoid using very heavy cardstock settings that may cause jams. Side-seam construction is usually more printer-friendly.
