Choosing the right machine for high volume pouch and bags packaging can be an overwhelming task without the right information. Among the most common packaging solutions is the continuous band sealer machine.
But, what is continuous band sealing machine? How does it work and where can you use this packaging machine? That is exactly what we shall discuss today.
What is Continuous Band Sealer?
A continuous band sealer is a unique packaging machine. This machine works by sealing your pouches or bags with heat even as it moves them along a continuous conveyor belt.
Continuous Band Sealer Machine Parts and Components
| Key Components of Band Sealer | Remarks |
| Heating elements | · Melts the sealing area for both pouches and bags |
| Conveyor belt | · Helps move bags through the sealing path |
| Cooling blocks or fans | · They harden the seals made on your bags or pouches for durability |
| Temperature controller | · Sets and maintains the temperature of sealing on your bags or pouches |
| Pressure rollers | · Mostly applies pressure on bags and pouches to form a very tight seal |
| Sealing belts (PTFE) | · These are non-stick belts that pass through the sealing area during sealing process |
| Frame and casing | · Supports and protects the internal components of the machine |
| Motor and gearbox | · These drive the sealing and conveyor systems to make work smoother |
| Tension adjusters | · Maintains the right tension and alignment of the machine |
| Guide rails or tray | · Hold and guide bags during the sealing process |
| Emergency stop | · A safety mechanism that stops or halts the machine immediately |
| Control panel | · Fully integrated with PLC and touchscreen HMI to control all operation during band sealing process |
| Printing device | · It is an optional feature. In most machines, it helps print batches and codes on the sealed bags |
How Continuous Band Sealer Works
The working principle of these machine involves many distinct steps. It is a systematic process, that ranges from bag or pouch preparation, all through to the sealing stage.
- Fill Bags – You will have to fill bags with your ideal products.
- Bag Placement – Place all your filled bags onto the conveyor belt of your sealer machine.
- Control Panel – Insert the required data and speed details into the control panel interface and enter it to begin.
- Heating Process – The conveyor belts begin to move your filled bags forward. It goes through the heated sealing jaws. These sealing jaws will warm the sealable edges of your bags or pouches.
- Seal – With pouches or bags sealable edges heated, heated pressure rollers of the machine press softened edges together. This helps to create that consistent and strong seal.
- Cooling Process – Your bags when sealed in step 5 are then moved through cooling blocks. These cooling blocks of the sealing machine hardens the seals. This ensures seals are durable and prevents seals from reopening.
- Discharging – When cooling of seals are completed, sealed bags are carried out with the conveyor and moved to the packaging section. Here, you can now package and distribute them.
Types of Continuous Band Sealer Machine
With the advancement in technology, there are a wide range of machine configurations. From small to large scale production, you will get a high quality machine the perfectly seals your products to the required specifications.
Among the most common machines include:
· Semi-automatic Band Sealers
Semi-automatic band sealers work by you (the operator) placing each bag on conveyors manually. Also, when the whole sealing is done, you pick your bags manually from the conveyor and package them. They are ideal for small-to-medium-scale packaging where you have workers to supervise the whole process.
· Fully-automatic Band Sealers
Fully automatic band sealers are mostly designed into automated packaging lines with reduced manual interventions. These sealers are designed to provide you with highly efficient sealing. Also, you get to have everything done automatically without many workers needed.
· High Speed Band Sealer
High speed band sealers are designed or engineered for sealing cycles that are extremely fast. So, for your high-volume production lines that demand consistency and speed, these sealer types are perfect.
· Horizontal Continuous Band Sealer
With these sealing machines, bags are sealed in a horizontal position. Also, you will need to place the bags flat for sealing to be done. They are ideal for dry and solid products such as powders or snacks.
· Vertical Continuous Band Sealer
Vertical continuous band sealers are perfect for sealing bags in an upright position. They make your sealing needs smooth and provides you with the right level of completion you need. You can make the most of them for packaging liquids, granular materials, or semi-liquids.
· Continuous Band Sealer with Vacuum
These vacuums extract air from your bags before sealing them. This is done to ensure the products within are kept fresh always. Also, it helps to prevent spoilage. You will find them being used in vacuum packaging for medical supplies, food, or sensitive items.
· Continuous Band Sealer with Nitrogen Flushing
This sealer type will seal your bag by flushing bags with nitrogen gas before sealing is done. It has been designed to do this in order to reduce the amount of oxygen within. You can use them commonly in food packaging to extend the shelf life of your products.
Benefits of Continuous Band Sealing Machine
If you are in the packaging industry, you may have noticed the increasing number of continuous band sealing machines. Well, this is attributed to the many benefits these machines offer. Among the most common benefits of using these machines include:
- Seals quickly and is efficient
- Consistency in sealing quality assured
- Reasonably priced to meet different production needs
- Compact and user-friendly design
- Easy to use
- Easy to adjust speed and temperature
- Ideal for different materials like laminated bags, plastic bags, and aluminum foil bags
Applications of Continuous Band Sealer
Irrespective of your industry, these machine fit a wide range of packaging solutions. Among the most common industries you will find these machines include:
- For pharmaceutical packaging of pills, powders, etc.
- Chemical product packaging of detergents, fertilizers, etc.
- Food packaging like coffee, dry fruits, snacks, spices, etc.
- For agricultural product packaging like seeds, pesticides, etc.
- For cosmetic product packaging like creams, face masks, oils, etc.
Conclusion
When you find that ideal continuous band sealer machine, you realize that the work goes smoothly. The level of reliability of this tool cannot be taken for granted. No matter the type you need, make sure the right brand is chosen to prevent issues later.
