MODULA SERIES

With our bag making machine of MODULA Series it is possible to produce t-shirt bags and bottom seal bags up to a maximum of 9 lines.
With MODULA-S, MODULA-SV and MODULA-SS models we differentiate our wide range of solutions for flat bags production.

Modula-S

– Collection with pins
– Up to 6 lanes

Modula-SV

– Collection with pins
– Up to 9 lanes

Bottom sealing bags with gussets collected on pins

Modula-SS

– Collection without pins
– Up to 6 lanes

FAST, FLEXIBLE AND RELIABLE

We have engineered and developed the MODULA Series models to guarantee productivity optimization, ease of operation and low maintenance.

MODULA-S for bottom sealed and T-shirt bags production with collection on pins.
MODULA-SV for bottom sealed and bloc-notes bags production with collection on pins.
MODULA-SS for bottom sealed bags production with collection with and without pins.

Standard lines can be configured with additional accessories and devices that allow you to customize your production:

Equipped for synchronized operation with our flexographic printing units from 1 to 8 colors with printing widths up to mm 2000.
Cold embossing units.
Micro-perforating devices and perforating units for bags that require aeration.
Film polarization equipment.
Attachment for glue points sticking bags production.
Collecting table arranged for automatic coupling to boxes machine.
COMBI device for bloc-notes bags production also on MODULA-S and MODULA-SS.

MODULA Series

	MODULA-S	MODULA-SS	MODULA-SV
Roll holder - Shaftless unwinder
Hydraulic system for lifting rolls from the floor. Maximum roll ∅ mm 1100 (∅ mm 1300 and ∅ mm 1500 on request). Automatic film tension control by multiple vertical dancing roller equipment and motorized rubber wheels. Pneumatic film guiding system as standard. Automatic machine stops at end of the film roll and in case the film breaks. Double overlapping or side-by-side unwinder (on request).
Slit-sealing unit
Nickel chrome slit-sealing blade device, suitable to cut and seal the film in multiple tubular lanes starting from one single roll. Electronic control and independent blades management. Automatic system to engage and detach slit-sealing blade from the film, when the machine stops.
Motorized post-gusseting equipment
Pair of rubber cylinders, with opening and closing pneumatic control, for perfect airtightness into the material. Mechanical devices for adjusting the depth of the gussets. Automatic quick film feeding system into multiple vertical dancing rollers unit. Motorized output conveyor groups with remote control.
Sealing bar with cold cutting blade
The modular sealing bar first cuts the film and only afterward seals. The film is cut by a serrated cold blade, motorized with oscillating movement. The modular sealing bar temperature is kept constant by a closed water cooling circuit. The sealing is performed with a Ni-Cr strip alloy plate. The strips coating is made with quick-change adhesive Teflon.
Quick change system from T-shirt bags to bottom sealed bags
The type of production from T-shirt to bottom sealed bags can be changed instantly by pushing a button. This selection instantly activates/deactivates one of the two sealing strips.
Collecting system with pins
Bags stacking system with thin pins at mm. 8 (MODULA-SV) or at mm. 105 (MODULA-S and MODULA-SS). Possibility to obtain bags in bundles with hot blocking. Packs of bags are made immediately after the sealing bar and contemporarily to the sealing phase. This system guarantees perfect bags stacking.
Collecting system without pins
Bags stacking system without pins with motorized locking bar. Possibility to obtain bags in bundles with hot blocking. Packs of bags are made immediately after the sealing bar and contemporarily to the sealing phase. This system guarantees perfect bags stacking.
Automatic collecting table
MF \| 2 for collecting bags with automatic hydraulic die-cutting of T-shirt and bean-type handles. Automatic die-cut handles collection. MF \| 3 for collecting bags. MF \| 5 for collecting bloc-notes bags with or without automatic hydraulic bean-type die-cutting All collecting tables are equipped with single or double folded automatic system.
Brushless servo motors
Brushless servo motors with four electronic axes are used on MODULA-S & MODULA-SS models for film feeding speed control, sealing bar motion control, carbon-fiber flying bars safety for bags in exit from sealing bar, drive and chariot positioning for moving packs of bags in the collecting table. Brushless servo motors with three electronic axes are used on MODULA-SV model for film feeding speed control, sealing bar motion control, drive and chariot positioning for moving packs of bags in the collecting table.
Bio Ready
Thanks to our innovative technology, all our machinery are able to process biodegradable and compostable films. We are able to process Bioplastics with a minimum thickness of 8 microns.
Ready 4.0
All our machinery are set up and equipped with web servers and OPC UA servers as required by Industry 4.0 specifications. We guarantee freedom and flexibility of integration between our machinery and our customers’ ERP or MES systems.
