Induction Sealing Wads: Different Types & things to look out for

By using induction sealing wads, you can ensure that your containers are airtight and the contents are protected against contamination by air, moisture, germs, and other outside elements. It is more evident if the product has been tampered with since the removal and reapplication of the wads leaves visible evidence.

Induction wad varieties

A wide variety of induction sealing wads are available, and most include many layers. A standard induction wad may be one of two varieties:

• Induction Wads That Come As One Piece

Once the lid is on the jar, an induction sealing wad is wrapped around the opening. Containers with caps like this are often designed to be used with a heat sealer that uses induction. The threaded bottle cap applies the required force, causing the sealing layer to adhere to the jar, resulting in an airtight closure.

• Induction Wads, Two Piece

Induction sealing wads that are two pieces are made of two layers of paperboard, one on top of the other. Afterwards, an aluminium foil layer is adhered to the paperboard using a wax coating. The bottom of the aluminium foil has a polymer film bonded to it. After the lid is fastened on the jar or container, it is run over an induction coil, which produces an electromagnetic field that oscillates. With the induction coil heating up, the aluminium foil also starts to warm up due to its conductive qualities.

When the wax is heated, it melts and is absorbed by the paperboard layer, releasing the foil from the cap. Additionally, the polymer film melts when heated, covering the top of the container. Airtight seals are created when the polymer cools. Two-piece sealing wads prevent product leakage by leaving a secondary seal on the bottle cap after the induction seal has been withdrawn from the bottle mouth.

• Induction Wads without Caps

Jars and bottles designed for use and disposal benefit from capless induction wads.

Induction Wads: What to Check For

Wads used for induction sealing are an essential part of any packaging process. Unfortunately, we often overlook crucial details when selecting the best induction sealing wads for your goods. Although cost and practicality are crucial, there are many more aspects to consider when tailoring a solution to your specific requirements

• Capacity to repel water

When using subpar induction sealing wads, leaks and spills are common. The wad is useless if the contents inside the wad are not secure. Make sure your seal wad supplier employs high-quality components in the production process. In addition, the wads must be watertight and unaffected by exposure to moisture. They are using induction wads like these guarantees that the product's contents will remain secure within the container during transport.

• Additions to Ensure Safety

It would be simple to make a fake or a pirated version of a generic induction sealing wad. Features that prevent duplication and do not lead to tampering with your items are indicative of a high-quality induction wad. Always check for safety features in induction sealing wads. Holography, security printing, watermarks, and product authentication with track-and-trace capabilities are a few of the security features that may be used. Sales and expansion may be achieved via induction sealing wads equipped with security elements to prevent theft or other unethical interference in the supply chain.
