Common questions
Are these envelopes compliant with USPS and shipping regulations?
Yes. The 9 x 12" size meets USPS standards for First Class and Priority Mail, while the gummed closure provides secure, tamper-evident sealing required for certified and insured mailings.
What weight paper stock is recommended for mailing documents?
Our 28 lb. kraft paper stock is ideal for standard document mailing. It provides excellent durability during transit while remaining cost-effective for bulk mailings without exceeding weight restrictions.
How do gummed envelopes compare to self-seal envelopes for security?
Gummed envelopes provide tamper evidence and a more professional appearance. The adhesive seal creates a visible break if opened, making them preferred for confidential documents, legal papers, and compliance-sensitive mailings.
Can bulk quantities be customized or printed with company branding?
Yes. Contact our sales team for custom printing options and volume discounts on cases of 1,000 or larger. Minimum order quantities apply for branded envelopes.
