What Kind Of Envelope Stuffing Machines Are There in the Market?

There are two kinds of letter folding and envelope stuffing machines: Rollers and air feed machines.

Entry-level and moderate volume letter folding roller machines can process anything from 50-5000 letters a day. And a high volume roller machine can work through more.

Formax FD 6306

Air-feeding machines last much longer and work on a wider array of paper types. And they don’t mar high-gloss finishes like the roller machines can.

The difference between the two types comes down to price for most businesses.

You have numerous choices of brands and models to choose from in this space. To get your shopping started, here is our list of some of the best envelope-stuffing machines to consider.

Choosing Envelope-Stuffing Machines

Maybe you’re one of those people who actually like licking envelopes. (If so, you might consider getting on the flavored glue trend!)

But when there are thousands of envelopes a day to get done, a machine is the way to go. After all, processing mail by hand takes approximately 12 seconds to fold, insert and seal, or 300 envelopes an hour. The most basic folding-and-inserting machine listed above will stuff at least 1,300 per hour.

So how to choose an envelope-stuffing machine? There are four basic questions to answer to narrow down your choices:

  • How many sheets of paper can the tray hold?
  • How many envelopes do you need to be stuffed per day?
  • What is your budget?
  • How much space is available for the machine?

Additional questions might include what types of items you will be mailing and the type of paper they use. Added features such as touch screens and network connectivity make nice bonuses.
