The MF microperforation unit is a true microperforation assembly that is easy to handle, easy to adjust, high-performance, very reliable, and safe. It can be easily connected to extruders, printing machines, welders, winders, and all other plastic film processing machines. It is particularly suitable for shrink films, low-density polyethylene, and generally for elastic (stretchable) films and paper.

The microperforation assembly consists of the following elements:

• End frames made of steel
• Rubber coating on the counter roller with grooves on the periphery of the body corresponding to the passage of the needles; the rotation of the roller is driven by the passage of the film (on request, or for specific applications, we can provide a brush roller).
• Paired gears for synchronous rotation of the rubber-coated roller and the microperforation roller to avoid any tearing of the film during perforation (only for pitches > 20 mm).
• Needle-carrying roller equipped with shells, on which the needles are mounted. The shells are half-cylinder plates with a width of 20 cm.
• Easy replacement of the needle shells without removing the roller from the microperforation unit. Generally, the needles have a diameter of 1.42 mm, but on request and for specific applications, we can provide a unit with a different perforation diameter.
• Protective cover to prevent contact with the needles. Up to 1600 mm in width, the pneumatic opening and closing movement of the microperforation roller is offered as an option and is only installed at the customer's request. Beyond a width of 1600 mm, it is essential. It is currently installed on the MF 3 and MF 4 models. Trace of the microperforation (the arrangement of holes in the material).
