Packing List Mailing Envelopes

Packing list mailing envelopes are clear or opaque adhesive pouches attached to the outside of shipments to hold invoices, packing slips, or customs documents so they remain visible and protected during transit

Select an envelope that fits your documents flat without folding; common sizes accommodate A4, letter, or smaller slips. Choose PVC or polyethylene for moisture resistance and durability, and paper versions if recyclability is a higher priority

Look for strong pressure-sensitive adhesives labeled for corrugated cardboard and common packaging materials; permanent adhesives are standard, while removable or low-tack options are available for temporary attachments or delicate surfaces

Yes—many packing list envelopes are sized for customs forms and designed with clear windows to display invoices or CN22/CN23 forms; choose envelopes that include a secure closure and full document visibility to meet international carrier expectations

These products are commonly sold in packs from dozens to large bulk quantities; prices vary widely by quantity, size, and material, with budget packs available under $50 and higher-volume or specialty packs extending into the hundreds

PVC and polyethylene envelopes provide good moisture resistance and tear strength for typical handling; ensure the adhesive and pouch seal fully cover documents to prevent water or dirt exposure during rough transit

Store them flat in a cool, dry place away from direct sunlight and extreme heat; keep them in their original packaging and use within the manufacturer's recommended shelf life for best adhesion
