Levapack Aluminum Foil Sealing Machines
LPE Aluminum Foil Induction Sealer Machines for Cans, Jars, & Bottles
The most critical aspect of packaged products is to ensure that they have tamper-evident packaging. If this seal is missing or breached, consumers may assume that tampering has been done and you will lose potential customers. This will have a great impact on your brand recognition strategy and your company’s image.
If you want to watch your sales escalate, keep your customers highly satisfied by providing them with products that are guaranteed to be tamper-evident. Aluminum foil induction can sealer machines help you do this by integrating them into your production lines. An automatic aluminum foil induction can sealer equipment would even be more ideal for streamlining the packaging process.
LPE, a packaging solutions manufacturer in China, has customizable aluminum foil induction can seamer machines for sale at affordable prices with guaranteed quality through our own manufacturing factory.
What is an Aluminum Foil Induction Can Sealing
Since an aluminum foil induction can sealing equipment is used in sealing containers using an aluminum foil, some also call them as:
- Aluminum can sealer machine/equipment
- Aluminum sealer machine/equipment
- Aluminum can seamer machine/equipment
These packaging machines are used to hermetically seal glass and plastic jars, cans, and bottles via induction sealing to extend product shelf life, prevent leaks, and most especially to provide tamper-evident seals. Aluminum foil induction can seamer machines are available in electrically-powered, handheld, and manual designs for sealing various closure sizes.
What is Induction Sealing?
Induction sealing is a non-contact method of bonding materials made from thermoplastics through electromagnetic induction which generates eddy currents to heat the materials. In the packaging industry, this process is used to hermetically seal a container cap having a foil laminate sealable by heat. In the case of our Aluminum Foil Induction Sealer Equipment, the foil laminate is an aluminum heat induction liner.
What is an Aluminum Heat Induction Liner?
You’ve seen these things covering bottle and jar containers when you open a packaged product such as peanut butter or bottled medicines. An aluminum heat induction liner is a silver foil at the opening of a container that proves that the packaged product is tamper-evident. They require an aluminum foil induction can sealing equipment to properly seal these liners to the can.
Moreover, a typical aluminum heat induction liner inside a cap is a multi-layered seal made up of the following strategically situated and designed layers:
- A pulp paperboard layer
- A wax layer
- An aluminum foil layer
- A polymer layer
The topmost layer, which is the pulp paperboard layer, nests against the lid’s inside part and is spot-glued to it. Followed by a layer of wax used to bind the pulp paperboard layer to the third layer, the aluminum foil, which is the layer that adheres to the container. The last layer at the bottom is the polymer layer which looks like a plastic film.
These four layers work together in order to achieve the necessary dynamics for a successful induction process to produce an airtight seal.
Major Components of an Automatic Aluminum Foil
Induction Can Sealing Machine
Whether a handheld machine for smaller productions or a deluxe unit for large productions, every aluminum foil induction can seaming equipment consists of two important components: a power supply and a seamer head.
#1 Power Supply
The power supply is where your machine draws its energy to start the sealing process. The appropriate strength of an aluminum foil induction can seamer equipment’s power supply depends on the container closure size and the speed of your production line.
#2 Seamer Head
The seamer head contains a coiled conductor with plastic housing. When the capped containers pass under this, the aluminum foil is bonded into the container to seal it. The design of this component is dependent on your application. The two most popular designs are flat and tunnel seamer heads.
Discussed below is the major difference between the two along with the advantages and disadvantages of each design type.

Flat seamer head designs disperse the electromagnetic field coming from the head widely.
- Can seal a wide area.
- Can accommodate a variety of closure sizes without changing the seamer head.
- Since the electromagnetic field is less concentrated, inconsistent sealing of the containers can happen if the container is not centered properly under the seamer head.
LPE’s Aluminum Foil Induction Can Sealing Equipment guarantees that the containers are sealed precisely through a strict quality inspection of the finished machines to ensure that the containers are centered properly.
Tunnel Seamer Head
Contrastingly, tunnel seamer head designs emit concentrated magnetic fields above and on the sides of the cap.
- Produces uniform electromagnetic fields for a more consistent seal.
- Produces a deeper field capable of sealing thicker caps such as child-resistant ones or caps with recessing liners such as push/pull caps and spout caps.
- Cannot handle a wide array of bottle neck finishes.
Whatever your aluminum foil induction can seaming equipment needs are for the seamer head, LPE gives you the freedom of customizing your own cap seamer equipment.
How Aluminum Foil Induction Can Sealing
The induction sealing process starts by supplying an already product-filled cap-container combination to the aluminum foil induction can seaming machine. The lid has already an aluminum foil heat induction liner inserted in it before it is capped to the container.
The cap-container combination passes under the seamer head, which is emitting an oscillating electromagnetic field, via a moving conveyor. As the bottle passes under the seamer head, the aluminum foil heat induction liner starts to heat because of the eddy currents. The wax layer, which is the second layer of the induction liner, melts and is absorbed by the topmost layer - the pulp paperboard layer.
When the wax layer melts completely, the third layer (the aluminum foil layer) is released from the lid. The last liner layer, the polymer layer, also heats and melts onto the plastic container’s lip. Once the polymer cools down, the created bond between the polymer and the container produces a hermetically sealed product.
The whole sealing process does not negatively affect the product inside the container. Though it is possible for foil overheating to happen which causes damages to the layer of seal resulting in faulty seals. To avoid this, LPE performs strick quality inspection through the whole manufacturing process of your customized aluminum foil induction can seamer equipment.
You’ll have a more convenient sealing machine operation as our machines feature a handwheel, switch button, and digital display of working current and voltage to achieve a more intuitive operation.
