Technically, paper pouch packaging machines are in two categories based on the paper pouch layout; vertical and horizontal configurations.

Vertical layout merely implies that the paper pouch has a vertical structure, and it is more preferred in this technology.

Simply put, paper pouch packaging is a comprehensive process that involves intermittent rotary movement of pouches in different stations.

Here is how this machine works;

Paper Pouch Loading

Preformed pouches are loaded into the bag magazine by a robotic arm and conveyed into the equipment by a bag feeding roller.

The robotic arm grasps individual bags using vacuum suction technique and loads them into the bag gripping section.

Bag Gripping

Proximity sensor detects a bag and allows vacuum bag loader to pick up and transfer the pouch to a set of grippers.

The grippers hold the bag as it moves around the packaging machine to different stations.

Printing/Embossing (Optional)

Printer is placed at this station if printing of embossing is required.

Mostly, the printer is used for placing dates, lot codes and batch numbers on pouches.

Paper pouch packer can use thermal and inkjet printers.

On the other hand, embossing option may be used for placing raised dates or lot codes on the bag seal.

Pouch Forming

The film moves to bag forming after printing.

This process overlaps film edges to shape the pouch accordingly and allows the sealing jaws to close vertical and bottom sealing.

If the pouch doesn’t have a zipper, the vacuum suction opens its bottom part and engages air blower only.

The machine has two sensors that detect presence of a bag.

Hence it only engages the filling and sealing stations upon detecting the presence of the bag.

Besides, it never fills and seals the product if the bag is placed incorrectly.

Instead, the bag stays on the rotary equipment until the next cycle.

Bag Filling And Sealing

Filling is accomplished by joining a bagging machine to a multi-head scale or another filling machine like a volumetric filler or auger, depending on nature of product.

The connected machines are synched electronically to allow the product to drop automatically once the bag is ready.

Filling unit is programmed to ensure correct measurement and release of discrete product quantities dropped in each pouch.

Product Settling

In some instances, loose products need time to settle to pouch’s bottom before sealing; hence the station shakes premade pouch gently to attain that.

Paper Pouch Sealing

The deflator components squeeze remaining air out of the bag before sealing.

Hot sealing jaws close the upper part of the pouch by forming a strong seam from pouch sealant layers using heat pressure and time.

Cooling And Discharge

The seal is strengthened and flattened by a cooling bar.

The finished pouch bag is then released from the packaging machine into a receptacle or conveyor for downline equipment transportation.

Paper pouch packers are available in different types, often based on various aspects, including operation, function, packaging style etc.

However, the notable types used commonly in different industries include the following;

Automatic Paper Pouch Filling Machine

It is a type where all the packaging functions are fully automated; thus, the process hardly requires human involvement.
