The working principle of 3 side sealing cartoning production line

Phase I- Primary Packing

To create 3 side sealing pouch, sachet, stick packing, you will need to load the products in the filling and sealing machine. The working of the machine is described below:

Film Formation

Film Formation

The film roll is adjusted in the screw roll of the machine and its linkers to make firm and intact network. A film is opened during work and rolled around the former to make a shape of the sachet or stick pack.

It is sealed on the left edge of the pack and bottom of the pack.

Products Filling

A 3 side filling and sealing machine

The product to be filled is simultaneously loaded inside the pack once the sealing done. Upon acquiring the correct amount of the product inside the final top seal is applied to close the pack and secure the product inside.

Pack Discharging

3 side seal pack

The prepared pack is separated from the chain of packs by the help of facilitated cutters or knives in the machine and discharge via ‘Exit’ or the outlet.

Connection

With the help of conveyor the prepared sachet, stick packs are transferred from filling and sealing machine to the cartoning line.

Phase II

This is the final phase where packed products are subjected the secondary packing. A cartoning machine is responsible for this process. The working step of this phase is mentioned below:

Product Loading

Product Loading

At first, the products are automatically loaded onto the conveyors using a robotic arm and feeder. The products are placed one by one on the conveyor.

Blank Carton Loading

Blank Carton Loading

The large stack of blank cartons is loaded on the blank magazine from where they are picked up by the grippers and taken to the carton erector section.

Carton Erecting

Carton Erecting

At the carton erectors, the sides of the blank carton are folded, and an open carton box is created. This step is carried out by mechanical arms or the suction devices that are effective in folding the blank cartons.

Product Feeding in Carton

Product feed

After carton erecting, the products from the conveyors are placed onto the erected carton. The product feeding mechanism differs based on the products. Gravity-based systems and pushers are used for placing the solid items in the carton while the accumulation systems precisely load the smaller items in the carton.

3 Side Sealing

3 side sealing

Upon product filling, the flaps of the carton are folded and sealed using hot melt glue or cold glue. For proper bonding of the sides, pressure is applied to effectively seal all the 3 sides. The upper or lower flaps are also closed and folded.

Carton Discharge

Carton Discharge

Finished cartons are then moved to the next step of the production line where labeling of cartons or preparation for shipment occurs by palletizing.

6.What are the types of cartons does 3 side sealing cartoning production line handle?

Cartons come in all sizes and forms. So, 3 side sealing cartoning production line can handle diverse carton types. Some of these carton types are:
