Aluminum Foil Sealer With Induction

Aluminum Foil Sealer with Induction

What is “aluminum foil sealer with induction”? aluminum foil sealer with induction is used for PP, PE, PET, PS, ABS, HDPE,LDPE and glass bottles, which utilizes electromagnetic principle to produce instant high heat to melt aluminum foil that then adheres to the opening of the bottles, reaching the aim of wet-proof, leakage-proof, mildew-proof and extending preservation time. A common type of inner seal is a 2 pieces inner seal which leaves a secondary seal inside the caps once the induction seal has been removed.  This is commonly used where issues of leakage are a concern.  Another option is the single piece inner seal where once the induction seal is removed there is no liner left in the closure.  You can also choose from seals that have a pulltab or ones that have a peelable seal leaving no residue on the bottle. You must be certain that the liner is compatible with the bottle material.

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.  
These packaging machines are used to hermetically seal glass and plastic containers 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 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.

Induction Sealing Applications

HLQ aluminum foil induction sealing machines for screw caps are ideal for sealing food, beverages, medical products, and cosmetics among others in various bottle shapes, such as round and square bottles, made from plastic. Furthermore, below are the various industries and products that LPE can seaming machines can handle.
Beverage Industry Wine, Canned beer, Soda, Water, Cider, Juice, Coffee and Tea, Carbonated Beverages
Food Industry Meat, Seafood, Vegetables, Fruits, Sauce, Jam, Tuna, Soup, Cannabis, Honey, Nutrition Powder, Dry Food (such as nuts, cereals, rice, etc)
Pharmaceutical Industry Veterinary supplies, Medical supplies, Powders, Pills, Pharmaceutical raw materials
Chemical Industry Cooking oil, Lube oil, Glue, Paint, Farm chemicals, Cleaning liquid, Ink and lacquers, Nuclear waste and radioactive substances, Automotive Fluids (petrol, oil, and diesel)

How Aluminum Foil Sealer with Induction Work

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. Before the manufacturing process, we do extensive consultation with you to properly understand your needs. This helps in determining the appropriate system necessary to handle a specific product such as the required machine sizing for a guaranteed safe packaging line. aluminum foil sealer with induction
