Cold Cutting Bag Making Machine MF-B
A computer-controlled 2-line bag making machine for flat bags: it seals first, then cold-cuts. Five models from 550 to 950 mm wide, with bags up to 1,500 mm long.
Voltage and frequency built for your country: 220, 380 or 440 V · 50 or 60 Hz.

Seal first, cut after
In hot cutting, a heated knife seals and cuts at the same time. In cold cutting, the machine seals the bag first and then cuts it with a cold knife, which leaves a clean edge on flat bags.
The MF-B works two lines under computer control. The manufacturer’s catalogue also shows it for polyethylene gloves: if that is your product, confirm it in the quotation.

Questions about the MF-B
What is the difference between cold cutting and hot cutting?
In hot cutting a heated knife seals and cuts at once; it is how T-shirt bags are made. In cold cutting the bag is sealed first and then cut with a cold knife, which leaves a clean edge on flat bags.
Can I make printed bags?
Yes, with pre-printed film. Tell us about your design so we can confirm the configuration.
How much does a cold cutting bag making machine cost?
It depends on the model: the five MF-B models differ in sealing width, from 550 mm (MF-B600) to 950 mm (MF-B1000). Send us the width, length and thickness of your bag and your voltage, and we send you a quotation within 24 hours.
Does the machine run on 60 Hz?
Yes. We configure voltage and frequency for your country: 220, 380 or 440 V, 50 or 60 Hz.
What is the delivery time?
It depends on the model and configuration; we confirm it when you place the order.
