Envelope Supplies: What to Stock?

Envelopes are a stationery cupboard staple, but when you’re setting up an office it can be difficult to know what to keep in stock.

DL Envelopes

DL envelopes perfectly accommodate a sheet of A4 folded into three and are the ideal size for sending out correspondence, cheques and invoices. Choose plain envelopes if you want to print out address labels or window envelopes if you prefer to see through to the address on the letter.

As with most envelope sizes you’ll have the choice between white or manilla. Again this is a personal preference but try to keep it uniform once you’ve decided.

C4 Envelopes

C4 envelopes allow you to send unfolded A4 sheets of paper and are ideal for sending out contracts or other documents that you don’t wish to fold. Choose from windowed or plain, and white or manilla.

C5 Envelopes

C5 envelopes are half the size of C4 and accommodate a sheet of A4 folded in half. Some may prefer to use these instead of DL envelopes, particularly when sending out correspondence of more than one sheet.

Gusset Envelopes

If you are likely to want to send out heavy-weight documents such as brochures, catalogues, prospectuses or reports, gusset envelopes come in useful. These heavy duty envelopes have a reinforced gusset bottom and expandable V shaped sides to maximise capacity.

Padded Envelopes

Many businesses may regularly use padded envelopes, for example, for sending out discs, memory sticks or product samples. Some may even use padded envelopes to send out small products purchased by customers.

Whichever envelope supplies you decide that you need, Office Allsorts has a great range at the best possible prices, so that you can fill the stationery cupboard for less.
