Frequently Asked Questions
What size rigid mailer do I need for greeting cards?
For standard greeting cards you’ll usually want a 6.5 x 4.5 inch mailer or slightly larger to allow a thin sleeve and backing board. These compact sizes keep cards from shifting while avoiding excess postage costs.
Are self-seal strips reliable or should I add tape?
Self-seal strips are convenient and secure for most uses, but some heavy shipments or environments with humidity may benefit from a secondary strip of tape. For higher-value items, add tamper-evident tape or reinforce the flap for extra security.
How can I add extra protection for thin prints?
Slip prints into a clear plastic sleeve, add a thin backing board or sheet of chipboard inside the rigid mailer, and consider corner protectors for framed or mounted pieces. This combination prevents surface scuffs and improves bend resistance without greatly increasing size.
