Product category: Bag and sack making equipment


Automatic bag-making machine MODULA 2000 SV for the production of bottom sealed bags and blocked bags with perforation with max. bag length to mm. 700 when using NO-STOP device. With this solution the machine runs in continuous without stopping for the indexing. Maximum bag length in standard running with pause: mm. 1200.


Servo-Drive automatic bag-making machines for plastic films MODULA 2000 are manufactured in the range SV to satisfy the need to produce bottom sealed bags and tear-off hot blocked bags.

The range of this machine, in addition to the advantages due to the use of the modular welding head, adds that of the stacking bags by pins system that consents to produce at high speed, and to eliminate piling problems, very thin bottom sealed bags.

The produced bags have micro holes situated at 8 mm. from the opened side.

These machines can also be equipped with a large range of film feeding groups composing complete lines for the production of bags in more lanes starting from one big roll.

Main features are:


Brushless motors used for: film feeding speed control; welding head assembly motion control; drive and chariot positioning for moving packs of bags in the indexing table.
Electronic Machine Management by an Industrial PC with a Human Machine Interface console utilizing a 19”video colour screen and keyboard. From this HMI, the operator may completely operate; view the production; change recipes, and maintaining the equipment as required. Complete alarming and historical events logging are also provided. In addition maintenance and trouble shooting information are provided for an easy diagnostic.
Bags up to 700 mm lenght are produced in a continuous sequence with NO-STOP operation. Bags up to 1200/2000 mm lenght are produced with PAUSE operation.
A single modular welding head incorporates a cam drive cold toothed cutting blade and Nickel- Chrome sealing wires suitable for the production of bottom sealed bags and bloc-notes bags with perforation and banana handle.
Perfectly stacked bags are made easily by thin cold pins. Cold pins are completely adjustable and may be removed and relocated as required.
Packs of bags are made immediately after the welding head and contemporarily to the sealing phase: this assure a perfect bags piling.
Automatic indexing table. Can be supplied in two solutions:

STANDARD used for the collection of flat or folded bags in 2, 3 or 4. On request, an extended version is available for collecting bags long up to 3000 mm folded in 4 or 8.
WITH AUTOMATIC PUNCHING EQUIPMENT for producing bloc-notes bags with perforation and banana handles in 1, 2, 3, 4, 5, 6 and 7 lanes.
