bagging machines

Open-mouth bagging machines – made in Austria

The open-mouth bagging machines from STATEC BINDER are specific packaging machines that can be used to pack and seal pre-made open-mouth bags. Since not every customer has the same requirements, the packaging machines for open-mouth bags are available in different versions:

1. For lower production capacities
2. For medium production capacities
3. For high production capacities

Our experts at STATEC BINDER will be happy to advise you on the appropriate filling technology.

How do open-mouth bagging machines work?

Before the bulk material enters an open-mouth bagging machine, it is weighed above the machine and then metered into the prepared open-mouth bag – according to specific specifications. Once the bag has been filled, it is then sewn, sealed, or hot glued. The sealed bag can then be palletized.

What are the advantages of open-mouth bags?

• High product protection
• Improved storage capability
• Easy to open & reseal
• Filling according to exact measurements

At STATEC BINDER, you can choose from various designs of open-mouth bagging machines to suit your product and your goals exactly. Our open-mouth bagging machines offer a high degree of flexibility.

What are open-mouth bagging machines suitable for?

Open-mouth bagging machines are particularly suitable if you are looking for an economical and intuitive solution to safely pack free-flowing bulk materials.

Open-mouth bagging machines are particularly suitable for companies from the following industries:

• Food industry
• Feed industry
• Chemical industry – such as fertilizer
• Petrochemical
• Agriculture
• Minerals & Fuels

Our open-mouth bagging systems are suitable for any type of free-flowing bulk material. Powdery products can also be filled with additional equipment.
Depending on the required output, there is a choice of three open-mouth bagging machines:

1. PRINCIPAC
2. CERTOPAC
3. ACROPAC

The CIRCUPAC high-performance packaging carousel was developed especially for flour and powdery products.

To guarantee the highest weighing accuracy, we equip our packaging lines with our high-performance net weigher. Our Over Tape Bag Sealer or our sewing machine are used to precisely seal the open-mouth bag.

Our open-mouth bagging machines at a glance

PRINCIPAC – High-performance bagging machine for open-mouth bags

PRINCIPAC is a fully automatic high-performance bagging machine for open-mouth bags for packaging free-flowing bulk materials. Depending on the bag material and type used, the bags are then either sewn, welded, or heat-sealed. The open-mouth bags are efficiently packed and made ready for transport in the following process:

1. With the help of vacuum suction cups, the bags are separated from a stack in the magazine and transported to the pick-up station.
2. Here, the bag is opened by means of a suction bar, placed on the filling clamp, and clamped tight.
3. In the meantime, the product is dosed and weighed by a STATEC BINDER high-performance scale above the filling clamp.
4. Then the weigh hopper opens and the product flows into the attached bag on the filling clamp.
5. The filled bag is then gripped by two gripper arms and placed on the conveyor belt behind it, from where it is transported to the bag closing machine.

Every single step that an open-mouth bag goes through in the packaging machine is checked in detail. In this way, we at STATEC BINDER can guarantee the highest quality with a time-optimized packaging process.

2. Here, the bag is opened by means of a suction bar, placed on the filling clamp, clamped tight, and filled.
3. The filled bag is then picked up and placed on the conveyor belt and from there transported to the bag closing machine, which sews, welds, or heat-seals the bag, depending on the material.
