It is a large-scale packing machine used in giant food, beverage, and other industries. It is equipped with a vast array of computerized parts that contribute to precise and accurate product filling. The biggest industries with high-out needs favour this type of sachet packing machine due to its quick processing.

It is equipped with easy-to-use features, safety gadgets, alarms, sensors, and, PLC controls that completely automatesachet packing.

Classification Based on Filling Mechanism

Auger Sachet Packing Machine

Auger Sachet Packing Machine

This machine is frequently utilized to fill dry powders and granules inside the individual sachet. It is a closed system that reduces product contamination. With the rotation of auger screws, the powdery product from the hopper slowly passes through auger plates into the sachet.

It is a volumetric sachet packing machine that loads a precise volume of product in one cycle.

Piston Sachet Packing Machine

Piston Sachet Packing Machine

It is mostly utilized for packing semi-solid, free-flowing, and pasty liquids inside the sachet. The filling device in this equipment is comprised of a hopper and piston cylinder that aids in fluidity of products. The forward and backward motion of the piston in the cylindrical devices forces the products from the hopper into sachets.

Pump Sachet Packing Machine

At the start, the bulk quantity of product is fed inside the hopper located at the top side of the equipment while the packaging film for forming the sachet is placed on the large film roll.

Sachet Formation

Sachet Formation

The film unwinds via an unwinding disk and is guided over the roller that tracks the film and keeps it aligned. The Film reaches the conical forming tube after moving over the roller. The forming collar part of the forming tube aids in shaping the sachet.

It folds and packages a sachet with the action of vertical sealing jaws. These sealing bars seal the edges of the film longitudinally, leading to the fabrication of a sachet.

Product Filling

Product Filling

In this step, with the signal from the PLC unit, the product present in the hopper travels down gradually and with the aid of filler, such as auger, piston, and pump, it is loaded into the newly fabricated sachet.

Sealing and Trimming

The sachet is removed from the machine and collected in the outfeed unit after cutting. The collected sachets are taken for boxing.

7.What are the Sealing Methods in Sachet Packing Machine?

There are different kinds of sealing methods employed in the sachet packing machine for airtight and accurate sealing of sachets. These methods are discussed in detail below:

Heat Sealing

Heat Sealing-Picture Courtesy: Infopack

It is one of the most frequently employed sealing method in sachet packing machine. Heated sealers exert high pressure to melt the inner side film and bond two edges of film together. This creates a tenacious and strong seal.

Ultrasonic Sealing
