Common questions
What documents fit inside these envelopes?
These envelopes accommodate standard 8.5" x 11" documents folded in thirds, plus invoices, packing lists, and tracking information. The 4 1/2" x 5 1/2" opening is designed for typical shipping documentation up to 5-6 pages.
How strong is the adhesive backing?
The adhesive is engineered to securely adhere to corrugated boxes, poly mailers, and kraft boxes in warehouse conditions. It withstands standard shipping, handling, and sorting equipment without peeling or lifting during transit.
Are these envelopes compliant with shipping carrier requirements?
Yes. The pre-printed "Invoice Enclosed" messaging meets USPS, UPS, and FedEx documentation standards, helping ensure proper handling and reducing claim disputes related to missing paperwork.
Can I order smaller quantities than a full case of 1,000?
We sell these envelopes by the case of 1,000 to provide maximum cost savings. For bulk operations, one case typically supplies 1-2 weeks of standard fulfillment needs, making it the most economical packaging solution.
