Envelope Feeder
- Mixed Thickness Feeder - 2 MTF2 SKU: PM-MTF2 $6,900.00
A mixed thickness feeder lets a mail opening system handle envelopes that vary from a single sheet to bulky contents in the same run, without the mail being pre-sorted by thickness first.
In real inbound mail streams, thickness variation is the main cause of jams and stoppages. A feeder built for it is what keeps a production opener actually running.
What we stock
We stock the Postmark MTF2 mixed thickness feeder, designed to work with Postmark automatic letter opening systems in high-volume mailrooms.
How to choose
- Mail variability — The more your envelope thickness varies, the more a mixed thickness feeder is worth.
- System compatibility — Confirm the feeder matches the opener it will run with.
- Throughput — Specify against your peak daily volume rather than your average.
- Pre-sorting effort — If staff currently sort mail by bulk before opening, that time is what this removes.
Frequently asked questions
What problem does a mixed thickness feeder solve?
Standard feeders expect fairly uniform envelopes. Real inbound mail is not uniform, so you either pre-sort by hand or accept frequent jams. The MTF2 feeds varied thicknesses directly, removing both.
Which openers does the MTF2 work with?
It is designed for Postmark automatic letter opening systems. Tell us which opener you run and we will confirm compatibility before you order.
Is it suitable for a small mailroom?
It is production equipment. For modest volumes an office opener such as the 1632 is a far more sensible spend.
How is it delivered?
Production mailroom equipment ships by freight. We will confirm delivery arrangements and site access with you beforehand.
