Packing Slip Envelopes

Packing slip envelopes, also called packing list envelopes, packing slip pouches or sleeves, or document enclosed envelopes, are self-adhesive poly pouches that stick to a carton and keep packing slips, invoices and shipping labels with the package. We carry clear-front, perforated and printed "Packing List Enclosed" and "Invoice Enclosed" styles from 4.5" x 5.5" to 10" x 12", sold by the case with volume pricing.

Packing Slip Envelope Sizes and Styles

Clear, Perforated or Printed?

Clear-front envelopes keep the document readable, with a white back that stands out against brown cartons. Perforated envelopes tear open without a knife. Printed "Packing List Enclosed" and "Invoice Enclosed" envelopes tell receiving staff exactly where the paperwork is: full face envelopes have a large orange panel across the front, and banner envelopes have an orange strip across the top with a clear window below.

How They Work

Slide the document in from the side, peel off the paper backing and press the envelope onto almost any shipping surface. The side-loading design keeps documents in place and shows if someone has opened it, and the poly film protects paperwork from moisture, dirt and scuffing in transit.

Wholesale & Bulk Packing Slip Envelopes

Every packing slip envelope is sold by the case, 500 or 1,000 per case, with volume pricing on larger orders and free shipping on orders over $2,000. For ongoing or high-volume orders, request a quote.

Packing Slip Envelope FAQ

  • Are packing slip envelopes and packing list envelopes the same? Yes. Both are self-adhesive envelopes that hold shipping documents on the outside of a package.
  • What size packing slip envelope fits a standard letter sheet? 9.5" x 12" or 10" x 12" holds it flat; 5.5" x 10" holds it folded in thirds.
  • Are the sizes inside or outside? Outside. The inside is about 10 mm (0.4") smaller each way.
  • Will they stick to corrugated boxes? Yes. The pressure-sensitive adhesive sticks to almost any standard shipping surface.
  • Can you print our own message? Yes. Request a quote for custom printed envelopes.
  • Are they side loading or top loading? Side loading: the document slides in from the side, which keeps it from falling out in transit.
  • What is the difference between full face and banner envelopes? Full face envelopes have a large orange "Packing List Enclosed" panel across the front; banner envelopes have the message on an orange strip across the top, with a clear window below so the document shows through.
  • Do you offer free shipping? Yes, on orders over $2,000.
