Since manual labor is expensive and time-consuming, the use of a machine would be more feasible to seal these bags. For this reason, continuous bag sealers are the perfect choice to seal thousands of bags and pouches quickly and efficiently.

1.What Is A Continuous Bag Sealer?

Continuous Bag Sealer-1

A continuous bag sealer is a machine that uses a conveyer belt to seal different kinds of bags and pouches. These machines seal the bags in a clean and secure manner, providing them with an excellent strength seal that is also visually pleasing to the eyes.  This machine is employed in various industries and its demand has been increasingly growing over the past few years due to a number of benefits it offers.

2.What Is The Working Principle Of the Continuous Bag Sealer?

Continuous Bag Sealer-2

The working principle of a continuous bag sealer is simple. This machine uses heat and pressure to seal the bags and pouches in an orderly manner. It requires a power supply to produce heat at the top and bottom of the heating blocks. Firstly the operator puts the bag or pouch between the two sealing bands. Secondly, the bag or the pouch is then sent to the heating field which is situated between the heating blocks which then seals off the bag or the pouch with the help of a roller.

The bag or the pouch is made to go through a conveyer belt where the sealing process is done by bands made up of PTFE.

3.What Are The Components Of Continuous Bag Sealer?

Let us discuss some of the parts of continuous bag sealer

Electric Motor

An electric motor is the main power supply of this machine and is one of the most important components since the machine won’t work in its absence.

Silicon Wheel

After the bag or the pouch is sealed off using heat, this silicon wheel is used to put pressure on the bag so that it sticks together.

PVC Chain Roller

This PVC chain roller is used to rotate the roller shaft.

Rubber Roller

Rubber roller is also used to press the pouch or the bag with the help of a rubber roller.

Conveyer Belt

This belt is automatic and is used to move the bags or pouches from one part of the machine to the other part.

Gear Set

The gear set makes a connection with the gearbox.

Potentiometer

This device has the ability to control the speed of the electric motor.

Thermo Couple Wire

This wire senses the temperature.

4.What Is The Purpose Of a Continuous Bag Sealer?

Various industrial sectors like pharmaceutical, chemical and food industries manufacture thousands of products every day. These products are put into bags or pouches to hold them. These bags need to be sealed off to protect them from any damage and save them from any contamination during their transport. In order to fulfill all these obligations, the use of a continuous bag-sealing machine would make perfect sense.

Since thousands of these bags need to be sealed off each day as quickly as possible, this machine would be an excellent choice to seal them.

5.What Are The Different Types Of Continuous Bag Sealer?

There are 3 different types of continuous bag sealer available in the market.

Horizontal Band Sealer

Horizontal Band Sealer

As the name suggests, the bags or the pouches are placed horizontally placed on the conveyer belt in this machine which are then made to go through the whole machine, sealing them off through the heating process.

Vertical Band Sealer

Vertical Band Sealer

In this type of machine, like the name suggests, the bags or pouches are vertically placed in the conveyer belt. The bags then move through the heating blocks after which the rollers put pressure on the bags to seal them.

Band Sealers With Nitrogen Flush

Band Sealers With Nitrogen Flush

This machine works by filling nitrogen gas in the bag or the pouch. Nitrogen gas is a non-reactive gas and stops oxygen (a highly reactive gas) from oxidation, thus preserving the freshness of the food items inside the bag.

Depending on the thickness of the bag, the pressure of the nitrogen gas can be adjusted accordingly and filled inside the packet and sealed.
