Sealing lines

MF TECNO has developed several heat-sealing systems that can hermetically close any type of bag in heat-sealable, coupled and co-extruded materials. "Hot bar" or, alternatively, "impluse" sealing devices can be used depending on the material of the bag and the customer's requirements.

All the heat-sealing systems are electronically controlled and can be adjusted with regard to sealing duration, pressure and application time.

The particular action of the sealing bars, allows them to be removed quickly for maintenance interventions or replacement of elements subject to wear.

The MF TECNO sealing systems allow the following types of bags to be used:

• Bags with or without lateral gussets
• Bags with blocked gussets
• "Doy-pack" or "stand-up" bags
• Bags with different types of zip
• Bags with handles

They also allow a punched handle to be made, thanks to a double sealing bar.

In the case of semi-automatic bagging systems, economical, effective and user-friendly manually-controlled sealing devices are also available. They are all equipped with the most modern safety devices, which make them compliant with the CE regulations regarding injuries.

Sealing can also be used to make "Pinch-Top" type bags, currently widely used in the milling and chemical industries. In fact, this bag has lateral gussets and glued bottom and, once filled, has the advantage of taking an absolutely regular form, recalling the appearance of a parallelepiped. The result is a bag similar to a valve bag.
