Types of Induction Wads and How to Choose the Right One

The seal inside the bottle or jar serves an important purpose of protecting the content till it reaches the consumer. The proper choice of induction wad can help to avoid leakage, reduce moisture or dust penetration from the external environment and even gives an indication of whether a particular bottle or jar has been tampered with or not. Not all wads suit all bottles and products.

The packaging products offered by Aastha Enterprises include induction sealing wad, aluminum foil induction sealing wad, vented wads, EP wad liner and PET / HDPE / Glass Wad. This list of products can prove useful for manufacturers from the fields of food, pharmaceuticals, cosmetics and chemicals to make the appropriate choice of seals.

Different Types of Induction Wads and Their Uses

There are various types of induction wads to fit the container and sealing needs. The selection will depend on the container material, product packed and type of sealing desired.

1. Aluminium Foil Induction Wads

Induction wads have aluminium foil coating which seals onto the container opening through induction sealing process. These are common for sealing containers that need to be sealed against any form of leakage and contamination.

Aluminium foil induction wads can be used with PET, HDPE and any other compatible containers based on heat-seal coating of the container. It is advised that one confirms suitability of the wad with container material before making purchase.

2. PET Induction Wads

Polyethylene Terephthalate (PET) containers are common for packing food products, nutritional supplements, personal care products and many others. PET induction wads come with suitable sealing material which seals with compatible PET bottle openings.

It is essential that one has the correct sealing layer and wad diameter that is suitable for the bottle neck in order to achieve proper sealing.

3. HDPE Induction Wads

HDPE bottles are commonly used for chemical products, house hold liquids, oil products, personal care formulations among others. HDPE induction wads are selected based on the material of the bottle and sealing requirements.

Aastha Enterprises has a number of HDPE 5 Layer Induction Wad in their product category. Buyer should confirm the exact layer composition and suitability with the bottle.

4. Glass Induction Wads

Glass containers are commonly used for packaging food products, health care products, cosmetic products and other products that need proper packaging. Glass induction wads are suitable for sealing with glass container openings.

The sealing material should suit the glass container opening and the induction sealing process. Buyers should also take into consideration the state of the glass opening since uneven surface can affect final seal.

5. Vented Induction Wads

Certain packaged products tend to produce gas and develop internal pressure while storing. Standard air tight sealing will not suit such products. Vented induction wads are meant to seal such packages and ensure controlled gas emission.

How to Choose the Right Wad for Your Packaging Line

The wad should not just be picked on the basis of diameter and cost. The whole package of container plus product needs to be taken into account.

• Verify the material of the container: Find out if the bottle or jar is PET, HDPE or glass. Heat seal film used should match the container.
• Product awareness: Oils, powder, liquids, cream and chemicals may need different sealing considerations.
• Identify the sealing requirements: Determine the kind of seal required – either single component seal, foil that can be removed or vented.
• Perform the test on the packaging itself: Do a sealing test on the bottle, cap and induction machine used before accepting bulk order.

This will ensure minimum rejection of the pack, poor seal and delays in production.

Why the Wad Construction Matters

Induction wad is not just the layer of foil. Each layer serves its unique purpose. The foil reacts to induction heating while the heat seal layer adheres itself to the container mouth. Other layers can be used for support, cushioning, or as an inner layer of backing that stays in the cap once it opens.

For instance, in some cases, the two-piece construction will have a backing liner remaining in the cap while the foil separates and adheres itself to the container, whereas in other cases it will be the one-piece construction, which means it becomes one sealing layer. It all depends on how the package opens and what the customer requires for resealing. Companies need to discuss these issues with Induction Sealing Wad Manufacturers.

It helps the supplier better understand client's needs and not supply inappropriate wad.

What to Check When Comparing Wad Suppliers

In order to place a regular order packaging companies must request available sizes, construction type, material compatibility and availability of samples. Minimum order quantity, packaging and shipping information must also be verified.

While comparing Induction Wad Suppliers it may be helpful to find out whether the supplier offers different kinds of wads for glass, PET and HDPE containers. When searching for Aluminium Foil Induction Sealing Wad Manufacturers it is necessary to clarify the foil construction and heat-seal layer.

Aastha Enterprises offers several of such wads enabling companies to compare their packaging requirements with one supplier.

Frequently Asked Questions

Can the same induction wad be used for both PET and HDPE bottles?

No, not necessarily. The heat-seal layer has to correspond with the material of the container. It is advisable to do a test before applying the wad to the containers on a regular basis.

What is the need of a vented induction wad?

It provides an outlet for releasing gases from packages with built-up pressure. The use of vented wads is only recommended when it is necessary for the product.

Is there any effect of wad size on the sealability?

Yes, it does. The wad has to suit the dimensions of the container perfectly. If this is not done, it will affect sealing.

What information do I need to provide for quotation purposes?

Share the bottle material, neck diameter, cap size, product type, required wad construction and expected order quantity.

Conclusion

Selection of the correct induction wad is possible only with knowledge about the container, the product, and the packaging process itself. Different container types like PET, HDPE and glass could have different sealing liners, whereas vented or double part types cater to certain needs.

Aastha Enterprises manufactures various types of induction wads and liner products. With information regarding the packaging samples and packaging needs shared prior to purchase, the appropriate packaging can be selected.
