Packing List Envelopes

Packing list envelopes for a clear document handoff

Choose packing list envelopes around the paperwork that goes on the carton. Compare the folded document's width, height and thickness with the pouch format, then check the loading sequence and attachment surface. A packing-slip envelope holds the document; a shipping label or printed carton marking serves a different purpose.

The three clear-face formats below are listed as 2 mil poly and supplied 1,000 envelopes per case. Their dimensions differ. These are listed product dimensions, not a promise that a document of the same size will fit inside with room to load and close the pouch.

Compare clear-face envelope sizes

PL471 is specifically described as back-loading: insert the document before attaching the pouch. Check PL470 and PL11 individually for their loading and attachment instructions. Do not transfer an opening format from one SKU to another because the material or case count matches.

Check the paperwork in its finished arrangement

Use the actual document packet for the fit check, including its normal fold and number of sheets. Place the information the receiver needs against the clear face. Confirm that the packet loads without forcing the opening and that text, routing details or barcodes remain readable in the intended arrangement.

Try the attachment on the same carton surface and location your packing team uses. Include any required printed message, closure or security specification in the purchase request. A clear poly face alone does not establish a tamper-proof or other certified security function.

The visible-face and document-order guide helps organize the handoff. When replacing a catalog item, the Uline packing-list envelope comparison keeps usable fit and loading method separate from nominal size.

Calculate envelopes before cases

Multiply shipments by envelopes used per shipment. At one envelope for each of 2,500 shipments, three 1,000-count cases supply 3,000 envelopes, leaving 500. At two envelopes per shipment, the same run needs 5,000 envelopes, or five cases. Extra sheets inside one pouch do not automatically mean another pouch is needed; check the packet's fit.

Keep mixed sizes on separate order lines. A requirement for 1,700 PL471 and 800 PL11 needs two cases of PL471 and one of PL11. That provides 3,000 envelopes total, leaving 300 and 200 in their respective sizes.

Request a packing-list envelope quote with each SKU, cases required, delivery ZIP and any document or loading requirements. Compare the delivered total against the physical envelope count for the selected formats.

Packing-list envelope questions

Printed packing-list and invoice-enclosed envelopes

A printed face helps identify the paperwork attached to the carton. PL12 is the orange “Packing List Enclosed” format; PL13 is the orange “Invoice Enclosed” format. Both list 4.5 × 5.5-inch dimensions and 1,000 envelopes per case. Confirm the usable document space with the folded packet rather than treating the nominal pouch dimensions as the interior.

For 1,800 packing-list pouches and 400 invoice pouches, order two PL12 cases and one PL13 case: 2,000 and 1,000 envelopes, respectively. The remaining quantities stay in their own message formats. Do not combine the physical requirement into one case calculation if the receiving workflow requires different printed faces.

PL411’s exact supplier listing identifies side loading. PL460 is a separately specified top-loading format. PL438’s supplier listing confirms the “Documents Enclosed” wording. Match the required face and opening from the exact SKU rather than transferring them between pouch sizes.

Send the required wording, folded packet size, loading method, carton surface and cases needed in the quote. A printed envelope and a separate adhesive message label serve different functions.

Choose a top-loading or side-loading document pouch

These are outside dimensions; check the usable opening with the actual folded packet. A larger outside dimension does not establish that a thick packet will load and close. PL460 and PL411 meet different loading requirements, even though both have the same printed packing-list message and 1,000-count case.

For 2,500 suitable top-loading PL460 pouches, three cases supply 3,000. For 800 side-loading PL411 pouches, one case supplies 1,000. Keep the two SKU requirements separate and confirm the attachment sequence on your actual cartons.
