1. Choose the Proper Size

Packing list envelopes come in multiple sizes:

- 4.5" x 5.5" → Small parts, invoices, repair slips

- 7.5" x 5.5" → Standard packing slips

- 10" x 12" → Bulk shipments, multi-page documents

If your documents fold cleanly without bending, you have the right size.

2. Front-Load vs. Back-Load

Each type works differently:

- Front-load (top load) → Easy to insert documents quickly

- Back-load → Stronger seal and better weather protection

For fast fulfillment → front-load
For protection in transit → back-load

3. Plain vs. Printed Envelopes

- Plain clear envelopes → Clean look, flexible for any business

- Printed “Packing List Enclosed” → Highly visible for carriers

If you want fewer delivery errors, printed envelopes help.
