Round Corner Packing Machine: The Complete Buying Guide In 2024

1.How to Define Round Corner Packing Machine?

Round corner packing Machine

A round corner packing machine is a specialized machine that creates a round corner packaging container instead of a typically straight one. This machine forms pouches or stick packs with circular edges instead of straight sharp edges.

Round corner packing machine forms, fills, and seals round corner packaging corners.

This machine increases the marketability and branding of the packaging containers by creating exclusive packaging containers that stick out in the crowd of typically straight-type pouches. These packaging containers provide a distinctive edge to the brands as rounded corners set them apart from rectangular corner pouches or stick packs.

2.How is a Round Corner Packing Machine Significant for Production?

A round corner packaging machine is highly beneficial for businesses, generating optimized quality products and impacting every aspect of production. Some of the prime advantages of round corner packing machine are discussed below:

Smoother Sealing for Safety of End-users

With its automation, round corner packing does not need labor supervision. This lowers the chance of human error that is inevitable in hand packaging. These errors are unavoidable and negatively impact product efficiency, as incorrectly packed products always lead to product rejection and recall.

3.How to Classify Round Corner Packing Machine?

A round corner packing machine is classified into broad categories that are differentiated based on their filling technology and their packaging container. Here is the classification chart and its explanation for simplified understanding:

Filling Device

Auger Round Corner Packing Machine

Auger Round Corner Packing Machine

This machine relies on a closed-filling device called an auger. In this machine, auger screws rotate to move the powders or granules inside the auger plate. These products go from auger plates to the filling nozzles from where these products are deposited inside the packaging containers. This machine is a favourite among manufacturers because it lowers contamination risk.

Piston Round Corner Packing Machine

Piston Round Corner Packing Machine

This machine comprised of pistons and cylinders. To and fro movement of the piston in the cylinder doses the viscous or free-flowing liquids inside the packaging containers. It is a highly accurate machine that measures the exact quantity of liquids and dispenses them in pouches or other flexible containers.

Pump Round Corner Packing Machine

Pump Round Corner Packing Machine

As the name indicates, this machine has several distinct pumps that rotate to fill the packaging container. The gear, lobe, and cavity pump complete one rotation to load and dispense liquids in one cycle. It is a positive displacement machine that packs a wide range of liquids inside the pouches. It dispenses foamy, viscous, stringy, and thinner consistency products.

Volumetric Cup Round Corner Packing Machine

Volumetric Cup Round Corner Packing Machine

For filling products by volume, the volumetric cup round corner packing machine is used.  These are often used for dosing dry powders in round corner stick packs or sachets. It consists of cups in which a pre-measured amount of powders is loaded from the hopper. This machine does not generate over and underfilling results.

According to Packaging Container

This kind of round corner pouch packing machine fills and seals ready-made round-corner pouches. It is a flexible manufacturing unit that generates highly secure sealing results. It works at far faster rates than a simple round corner pouch packing machine and consequently has quicker loading and sealing cycles.

Round Corner Sachet Packing Machine

Round Corner Sachet Packing Machine

It is a specialized kind of equipment that produces round corner sachet instead of simple standard edges. It is highly popular in industries because it fabricates highly appealing pouches. It encloses the round corner sachet on three or four sides. Different filling systems, like auger, net weigh, and other volumetric fillers are present in this machine.

Round Corner Stick Pack Packing Machine

Round Corner Stick Pack Packing Machine

This machine has specialized cutting and sealing components that make stick packs with round corners instead of regular stick packs. It has one or more lanes that improve the processivity rate of the round corner stick pack packing machine. The sides of stick packs are closed using heat, pressure, or ultrasonic waves.

According to the Number of Lanes

Single Lane Round Packing Machine

Single Lane Round Packing Machine

It is a simplified category of round corner packing machine. It is a more convenient design that forms, fills, and seals small sachets and stick packs as it only has one forming unit and two sets of sealing jaws. It is usually seen in smaller and medium setups because it only loads one pack at a time. Single lane round packing machine is less expensive.

5.How Does the Round Corner Packing Machine Work?

The working round corner packing machine works is simplified and includes three main steps. However, we are giving a detailed description, so you can learn more about the round corner packing machine:

Step 1: Placement of Packaging Film In the first step, the operators or robotic arms put the packaging film over the film holder. This film is unwound by the rotating film holder and moves over rollers. These parts maintain film tension.	Placement of Packaging Film
Step 2: Forming of Packaging Container In the next step, the film reaches the conical-shaped part called the forming tube. By folding and wrapping, the forming tube and forming collar fashions a pouch or sachet-like structure. The bottom part is fused by the horizontal sealer.	Forming of Packaging Container
Step 3: Vertical Sealing The vertical sealer converts a pouch or sachet-like structure into the proper pouch by sealing its longitudinal sides. These sealers also form a middle seal depending upon the type of pouch.	Vertical Sealing
Step 4: Filling The filling devices measure and dispense precise quantities of solids and liquids into the filling nozzles. These parts rapidly fill the pouch or sachet.	Filling
Step 5: Horizontal Sealing When the filling stops, the top part or seam is melted and joined by the horizontal sealer. These sealers seal the top side of one packing container and the bottom side of another packing container.	Horizontal Sealing
Step 6: Cutting and Discharging Lastly, the two packing containers are disjoined from one another by the sharp blade. The finished round corner packing container is discharged on the product conveyor or outfeed chute.	Cutting and Discharging
