Frequently bought with

Common questions

Are these envelopes compliant with USPS and shipping regulations?
Yes. The 10 x 13" dimension meets USDA, USPS, and international postal standards for standard business mail and parcel classification. The heavy gummed closure provides the tamper-evidence required for secure mailings.
What weight documents can these envelopes safely hold?
The 28 lb. paper stock and gummed construction support documents up to approximately 2-3 lbs. depending on contents. For heavier items, we recommend Packrift's reinforced mailer options.
How do I activate the gummed seal?
Simply apply moisture to the gummed flap using a wet sponge, spray bottle, or envelope moistener. The adhesive activates instantly and provides a permanent, secure seal suitable for postal sorting equipment.
Can I customize these envelopes with logos or return addresses?
Yes. These white gummed envelopes are ideal for custom printing. Contact our sales team for bulk printing services and minimum order requirements to add your branding or return address.
