SealerOn™

Safe, Affordable, Handheld or Bench Top Induction Sealing Machine

Following frequent inquiries from smaller businesses, some start up companies, and testing labs looking for a reasonably priced induction machine, we have decided to make available a safe and affordable induction sealing unit.

Smaller businesses have low budgets in mind, but it doesn’t mean that they are ready to compromise machine safety and the integrity of their products.  Regrettably, there are not too many good options available in the market.  The majority of low cost induction sealing units do not present CE safety certification for LV and EMF.

Induction Machine CE Safety Certification for LV and EMF

The CE mark should be applied in order to legitimately market electrical and electronic products in the European Union (EU), but only after you have proven compliance with all applicable directives.  Compliance is established by testing the applicable harmonized standards for the safety of electrical and electronic products in relation to the effects of electromagnetic fields (EMF) and EMC on the functional safety of equipment. CE marking requirements now include compliance with electromagnetic field and electromagnetic compatibility standards. Manufacturers must ensure that products already on the market comply. This is precisely the reason why almost all other low cost induction sealing units do not have this CE safety certification.

Safe Induction Machine Option

The conception of SealerOn100™ was brought about by this need to supply the market with a machine that is certified safe and efficient. Induction machines generate high current and high electromagnetic field to accomplish their tasks. The birth of SealerOn™-100 has filled a gap in the SealerOn™ range that has provided a dependable solution to higher throughput equipment our clients are familiar with and put their trust in.

Immediately after its initial launch, we were flooded by a large number of inquiries. The unit is fully serviceable and it is fashioned to have its main electronics replaced in under 5 minutes!  Watch our video:

How Induction Sealing Takes Place

Induction sealing is a straightforward and simple process but an efficient way to seal bottles. The filling machines fill the bottles and are capped at some point.  The plastic cap has an aluminium foil liner inside.  Once the capped bottle passes under the induction sealing machine, which transmits electromagnetic energy to the foil liner, the liner becomes hot and welds itself to the neck of the container which remains in place even when the cap is removed.  The aluminium foil provides a tight seal that helps  prevent leakage, provides tamper evidence and can improve the shelf life of the product.

For small production run of sealing a few hundred units a day, SealerOn™-100 is a good solution.  Highly recommended for:

  • smaller or start-ups businesses looking to introduce a new product in the market
  • ideal for laboratory testing and applications
  • a low cost backup measure for higher end induction equipment

When you have time to properly align the sealing head visually, the SealerOn™-100 can be supplied with just a sealing head or wand. To insure a steady and even sealing, it is essential that the sealing head is level and well centered. The option of a stand to hold the sealing head and a locating bracket that aligns the product under the sealing head is made available to eliminate alignment errors.

We are proud of our SealerOn™ range of induction sealing equipment that performs reliably, safely and are easily serviced. We are delighted to be able to present a realistic and safe alternative for those in need of low budget, bench top or hand held induction sealing machine.

Fully Automated Filling Machine Features

  1. The machine feeds empty tubs into three lanes of an indexing (Start-Stop) conveyor on the machine.
  2. PLCs of the Filler and Heat Sealer talk to each other to time when filling takes place.
  3. Sensors on the Machine check that tubs are loaded properly and that tubs are present when they are under the filling stations.
  4. An accurate three head piston filler fills the tubs.

Heat Sealing Machine Process

  1. The Filled Tubs are indexed to underneath a Heat Sealing Station.
  2. Heat Sealing Foil has been indexed into place above the tubs and infront of a cutting and sealing mould. The mould has heating elements carefully temperature controlled and the mould descends to press the film onto the tubs.
  3. The Sealed Tubs are then indexed underneath the Lid Denester.
  4. A rotating Cylinder and suction cups take 3 lids from the bottom of the lid stacks and rotate to gently place the lids on top of the sealed tubs. At this stage the lids are not firmly pressed into place.
  5. ‎The tubs with loosely fitted lids are indexed under a pressing station to firmly place the lids into place.
  6. A roller after this stage is the final assurance measure to make sure the lids are pressed firmly into place.
  7. ‎Finally, the filled tubs with lids are lifted from the conveyor where they are positively slid onto an awaiting finished product conveyor.
Filling and Sealing Machine Speed

The filling and sealing Speed of this three lane system is designed for up to 40 Tubs per minute. Less viscous product could be filled faster. Higher speeds are of course possible with wider equipment fitted with more lanes.

Our SealerOn fully automatic filler and heat sealer equipment calls for minimal operator intervention. Normally, operators only need re-supply packaging components simply by loading supply hoppers and also taking away completed cartons.

SealerOn™ Large Caps

Large Caps

The SealerOn™ Induction Sealing Machine range is a versatile entry level range aimed primarily at Flat Cap induction sealing applications. 

The SealerOn™ 3000 is typically rated for Flat Caps of Diameter 20 mm to 120 mm traveling on a conveyor at speeds up to 20 Meters (60 Ft) per minute.

The Actual Speed needs to be determined with the Cap, Lining Material and Bottle combination to hand. The Standard frame Allows the Sealing Head to be adjusted from 710 mm to 1200 mm above the floor Level. This height range can be “offset” up or down upon request. Technicians are not expected to repair any components.

Ideally a spare Generator is on hand or can be provided while the Generator is sent to our manufacturers service center for repair.

SealerOn™ Induction Machines – Take a Closer Look

What is Induction Sealing?

Induction sealing is a common packaging process to bond a foil seal across the opening of container, jar or bottle.  Usually the foil seal is placed into the cap or closure of the product to be sealed and then the cap or closure is placed over the filled product.  The product then passes beneath an induction sealing machine and without ever touching the product the machine bonds the foil to the opening of the product.

How Induction Sealing Takes Place?

As soon as the container has been filled and capped – with a closure fitted with an induction liner – it travels beneath the induction sealing system. The non-contact heating system welds the liner to the container resulting in an air-tight and water-tight seal. Induction sealing machines or sealers, sometimes referred to as heat sealers, facilitate a product seal by emitting a high energy concentrated electromagnetic field. This field is created using high current thick windings (coils of wire), with voltage and current that switches back and forth at many thousands of times per second. The electromagnetic field passes through the air and the plastic of the containers cap to reach the Aluminum of the Induction Liner.  The field then generates high frequency alternating currents on the surface of the foil which causes the foil to heat up.

Bonded to the Aluminum is a heat seal layer – usually a polymer layer that will melt with heat. When this heat sealing layer melts its bonds with the top surface opening of the container and as it cools it “sets” in place with the neck or rim of the container. The Food and Drug Administration regards induction sealing as a highly effective method of tamper evidence.

SealerOn™ Flat Caps

Flat Caps Original

With Induction sealing it is important to identify if your range of plastic caps is considered “Flat Caps” or specialty caps.

A “Flat Cap”, generally speaking, refers to a cap where the plane of the induction liner is within 4.0 mm of the plane of the Cap’s top surface.

See the picture below:

Flat Cap Diagram

With only Flat Caps, a Flat Sealing Head can be provided.
With A Flat Sealing Head it is possible to cater for a wide range of cap sizes.

The energy transfer for a Flat Sealing Head is not as efficient as a Tunnel sealing head but the versatility often makes up for the reduced speed throughput compromise of a Flat Sealing Head
