Sometimes when you open up a jar of fruit jam or fruit pulp, we want to know how it was sealed shut without using any lids or caps, and we end up wondering about what could've been used- a foil sealing machine!
Foil sealing machines are devices used for sealing foil seals on jars or bottles before they're capped. A foil sealing machine will make sure your jars stay safe and secure so you don't have to worry about leaks!
While sealing has been around for years in the packaging industry, it continues to be the only way to create an airtight package. In this article, you can learn about how sealing works and which types of technologies are available.
Our Foil Sealing machine is hand-operated and in this blog, we will learn how a foil sealing machine works in-depth and which packaging materials are suitable for sealing.
How A Foil Sealing Machine Works
A sealer will create a permanent bond between two layers of material. Though there are many different ways to seal materials together, the most common way is through heat and pressure applied evenly over both sides of the product being sealed.
This provides excellent protection against dirt and dust or other contaminants getting inside your product. For instance, it protects them during shipping and also increases the shelf life of the product.
Factors That Make A Good Sealed Packaging
It would be mistaken to say that the width of the seal has anything to do with how well it seals. A 1mm seal will provide identical results as an 8mm seal when it comes to keeping moisture out of the container.
The three crucial factors for a better-sealed packaging are:
1. Heat
2. Pressure
3. Packaging Material.
A foil sealing machine works on two principles based on its technology-
1. Manually
2. Automated
Manual Foil Sealing Machine
Also known as hand sealers, manual sealing machine consist of resistance wire or sealing bars that are heated up to a particular temperature.
The packaging is placed inside the machine, with the resistance wire or sealing bars kept at the point where it is to be sealed. The device is closed, causing heat and pressure to be applied to the packaging, which then gets fused.
The machine needs to remain closed for several seconds depending on the packaging material. If you use our tabletop hand sealer, however, cutting through the tubular foil in one clean motion will leave your package sealed and ready to ship!
Due to being manually operated, the speed of the foil sealer is regulated by how fast or slow the user operates it.
Advantages of Manual Foil Sealing Machine
Some of the benefits of using a manual foil sealing machine include:
1. It comes at a feasible price and is easily available in the market.
2. This sealing machine has a compact size, thus, enhancing its portability.
3. It is compliant with different sealing materials such as aluminum, poly films, and paperboards.
4. It comes in different sizes that fit your industrial needs.
5. This sealing machine provides a tamper-proof sealing solution.
Automated Foil Sealer
An automatic foil sealing system relies on electromagnetic induction to create an airtight seal over the containers. Here is the step-by-step description of the function of an electromagnetic induction sealed foil packaging machine.
Preparation Phase:
You need to make sure your control panel is properly functioning. The unit needs to be safe, and the lubricating fluid and other components must be for proper and quick functioning.
Preparation Of Screening Material:
The automated system recovers the screening materials and takes place one by one at this point in the process. A common induction layer consists of a paperboard, an aluminum foil, and a heat-sealing plate.
The shield faces are sealed on the board and to keep it intact put some spot glue on the lid. This will make it easier to remove or replace the seal.
The second plate has wax that sticks the paper panel to the aluminum foil. The aluminum foil is situated on the bottom layer of the seal.
The bottom layer might be made up of a polymer film or thermal screen.
Placement Of the Seal Lacing On The Cap:
Place the seal on the lid before you glue it on the bottle and put it on the conveyor under an induction coil. The induction coil sticks the cap with the seal by emitting a variable electric field, which warms the aluminum foil due to the eddy current.
Cooling:
The hot polymer sets up like glue and creates an airtight seal for the container. This can ensure that the seal remains intact so you don't have to worry about anything getting spilled.
Seal Strength Inspection:
The sealed containers and jars pass through a seal inspection. The inspection will verify the strength of the seal to ensure it is sufficiently tight and firm.
Advantages of Automated Foil Sealing Machine
The following are the main advantages of using the automatic foil sealing machine:
The sealing process is faster and can seal many jars within a short time, making it suitable for large-scale plants.
1. It has an adjustable human-friendly interface that allows the operator to dictate the sealing parameters.
2. It does not require extra human labor to assist in its operations hence, reducing the labor cost and production cost.
3. It easily gets integrated into the production line.
4. The machine is adaptable to different types and sizes of jars, containers, and bottles.
5. The automatic settings allow the machine to operate continuously without pausing.
6. The sensors in the machine automatically detect any errors and immediately stops the operations.
Well, we hope this article has helped you know all about foil sealing machines. With this information, you should be able to decide what kind of a foil sealing machine you require for your business.
Don't forget to ensure that it adheres to the right quality standards and it fits your production needs. If you still need any help, do not wait any longer get in touch with Smart Packaging Systems and order your custom foil sealing machine at an affordable price.
