Frequently Asked Questions
What is a stay-flat mailer envelope?
A stay-flat mailer envelope is a rigid, non-bending envelope designed to prevent valuable contents like photos, certificates, and important documents from creasing. Crafted from sturdy white board or Kraft material, it ensures items arrive flat and professional.
What can I use a 7 x 9 1/2 envelope for?
The 7 x 9 1/2 stay-flat mailer is ideal for shipping photographs, marketing prints, small artwork, brochures, and important documents requiring superior protection. It is a highly popular size for e-commerce sellers, photographers, and professional offices demanding premium presentation.
What is the difference between Kraft and White Board mailers?
Kraft mailers are made from durable brown paper, offering a classic, eco-friendly look suitable for packaging and organic branding. White board mailers provide a cleaner, highly polished appearance, making them perfect for professional correspondence and photo deliveries that require maximum visual contrast.
Why choose Peel & Seal envelopes over gummed ones?
Peel & Seal envelopes are chosen because they are faster, cleaner, and more secure than gummed ones. Users simply peel the protective strip and press to close—no moisture is needed. This modern seal creates a strong, tamper-resistant bond, which is ideal for secure shipping and long-term storage.
Are 7 x 9 1/2 envelopes mailable through USPS?
Yes. 7 x 9 1/2 envelopes are fully mailable through USPS and meet guidelines for First-Class, Priority Mail, and Media Mail, provided the shipment meets standard weight and thickness requirements. Their rigid construction ensures the safe delivery of delicate items like prints and certificates.
How many sheets of paper fit in a 7 x 9 1/2 envelope?
A standard 7 x 9 1/2 stay-flat mailer is designed to comfortably hold approximately 10 unfolded sheets of standard 20 lb paper or several photographs and thin brochures. The robust, rigid structure guarantees that the contents remain flat and unbent, which is ideal for presentations or archival use.
Are 32# Kraft envelopes stronger than standard mailers?
Yes. The 32-pound Kraft paper is a premium-grade material that offers significantly enhanced durability and tear resistance compared to standard 24# envelopes. It is favored for secure e-commerce shipping, high-value photo deliveries, and professional mailings that require superior strength.
