Documents Enclosed Wallets for UK Sellers: Sizes, Plain vs Printed, Buying Direct

In short: In the UK packing list envelopes are called documents enclosed wallets; choose A5 (18 x 25 cm) for an A4 invoice folded once, DL (14 x 26 cm) for a letter-fold and A4 (25 x 33 cm) for flat export paperwork.

In Britain the self-adhesive plastic pouch stuck on a parcel to carry the invoice is usually called a documents enclosed wallet (also "document enclosed envelope" or "packing list wallet"). It is the same product American sellers call a packing list envelope: a clear film front, a self-adhesive back with a peel-off liner, and an opening on one side.

Plain or "Documents Enclosed" print?

A plain clear wallet is the cheapest and lets couriers read the document through the film. Wallets printed with "Documents Enclosed" or "Invoice Enclosed" in red or orange are easier for warehouse staff to spot and can hide prices from view. Our standard wallets are clear; printed wording is made to order.
