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.

MeRo Flat Caps

Flat Caps

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:

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

MeRo Induction Sealer Machine Range

We believe there is no better value medium priced “High End” Induction Sealing Equipment. There are unique features to allow process validation and adjustable width sealing head tunnels are available.

MeRo Induction Sealer Machines feature:

An Air cooled system (Absolutely no need to water cool the induction head).
Compact construction for easy integration into the filling line.
High power efficiency thanks to the configuration of the power circuits and the use of IGBT modules.
Sinusoidal output waveform (Not Square or chopped).
Constant and Precise Output power due to the configuration of the regulation circuits.
Easy to use controls that display operating parameters and alarm signals.
Remote control Start-Stop interface.
Power variation monitor which can be set by the user to activate an alarm.
Manufactured in accordance with EN-60204-1 standards, Electromagnetic (EMC) compatibility in accordance with EN-5511 and EN50082-2 standards.
Motorized height adjustment
Set-Up Validation providing an Energy absorbed reading- A key advantage over Nearly Every other make

Depending on the range of product and cap, lid, closure shapes, different sealing heads can be supplied.

Options include:

Missing Foil Detection with Bottle Eject Mechanism or Signal
Bottle Accumulation Detection to avoid the situation where bottles are stalled under the active sealing head.
Pressurized Cabinet version to work in dangerous areas.
Fieldbus connection to the production process ASI/PROFIBUS/CAM OPEN/DEVICE NET
Integration of power regulation proportional to the speed of the conveyor via feedback from your existing conveyor’s speed controller. This is another key advantage that MeRo are able to offer over nearly other make.

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.
