Investigating Glass Induction Sealing

Below are excerpts from an email that was sent for an inquiry which we published on this blog as part of FAQ.

Thank you for your earlier messages and a link you sent I see the glass you are considering to use for induction sealing looks like the following:

Your Questions 01:
It has been confusing, because I have gotten or read contradicting things. Mostly I have been told that we should use CONDUCTION machines for glass, because most INDUCTION relies on caps. I have also been told that there is only one kind of liner/seal that works on glass, and that is called INDUCTION (very confusing).

I believe both of your companies Adeneli and SealOn only make INDUCTION machines, and lids/seals for INDUCTION machines, not CONDUCTION. Is this correct?

Even though I read on your website, that INDUCTION LINERS only work on INDUCTION machines, again that contradicts what others have said so I wondered if you could elaborate on that. Why do you say it won’t work with CONDUCTION machines?

Our Answers01:
Our specialty is Induction Machinery.

We can tell you that usually induction sealing is done on products that have caps because the induction seal is held in the cap against the containers sealing edge with some cap tightening force for the induction cycle.

Where there is no cap on the product or where the cap interferes with the induction process (either it has Metal content or is an unusual shape) we have a very special range of induction sealers called “Capless Induction Machines”

Glass Induction Sealing is a tricky area of induction sealing dependent on the glass and the contents as it involves a hot melt adhesive layer which will perform quite differently depending on:

-The glass
-The contents
-The induction sealing material
– The induction sealing parameters including:
– The length of the induction cycle
– The Intensity and the “profile” of the induction cycle
– The pressure on the seal during the induction cycle
– The cooling period before releasing the pressure of the sealing head
– The shape of the induction coil; sometimes it needs to extend “around” the lip of the container
– The dead fold properties of the foil

Heat Conduction machines are NOT our specialty, however, I can tell you they rely on a sealing surface to be heated using heating elements and the sealing surface needs to maintain a temperature that is in a range that suits the sealing material and the container such that the sealing material and the container can fuse/melt together.

When sealing onto Plastic , which is not much of a heat sink, maintaining the sealing surface temperature is quite straight forward and you can expect the material and container to fuse/melt together.

The heat source for an induction machine is the induction process onto the sealing foil – it is an instant source of heat for the period of the induction cycle. When sealing onto glass it is usually a process of melting an adhesive (under pressure), and allowing the adhesive to cool/set before you release the pressure

Your Questions 02:
I see that you say you have cap-less that works on glass but I can’t tell if they can be custom printed, and roll over the sides like we want. I also can’t tell if you have smaller scale, table top machines, that are manual or semi-automatic that would work for the cap-less glass application. I doubt we could invest in a large conveyor belt automatic machine at this time.

Containers-I have also read about possible specially treated glass for using foil lids, but I can’t tell if this is a necessity or not and if so how to go about it. The place I read this regarded yogurt, and since ours is not a food product or liquid or powder, I wonder if this treated glass makes the bond much stronger for those purposes but that it would still seal without treated glass. Because for our purposes it would not have to be overly strong, and we want to have it fold down the sides which would help secure it.

Our Answers02:
On our side we can provide glass sealing induction foil.
For induction foil the MOQ of foil is 3000m² = 32000ft² – Probably too much for a pilot operation
If your Glass opening was 75mm or 3” in Diameter that would equate to about 470,000 Glasses
We can also supply this material in much smaller quantity without printing – MOQ about 10,000 candles worth.

The entry level machine that we are confident works with our Material (subject to tests) is our Benchtop Capless Machine.

The Sealed finish is as you see it in the video – a little bit wrapped down the side but not much.

As your contents are not food and essentially dry it should be straight forward, however, if your product contains essential oils these can wear away at a what looks like a good induction seal; so you need to test the longevity of the seal.

For more of a wrap down the sides it can be done, though, for pilot operations the material needs to be supplied pre-formed.

Pre-formed liners require tooling charges and the pre-formed liners are a lot more expensive than simple pre-cut flat liners.

Again, for pre-printed you need to purchase that MOQ.

Note with plain liners you can always get labels to apply to the sealed glass. We have label partners we can put you in contact with.

We also have the ability to provide you with the Epson Colorworks printers where you can print your own labels.
I hope this is a good start for your look into machinery and materials to achieve the induction sealing across the top of your products packaged into Re-purposed Glass.

*Labeling vs Labelling: We understand that you may see ‘labeling machines’ and ‘labelling machines’ within our web content. These are synonymous- just spelled differently in different regions of the world. We want our posts to be available to our world-wide audience, so we freely interchange the spelling to encourage easy searching for our content. Please rest assured, we are doing this on purpose!

Used Labeling Machinery: Hidden Costs You Did Not Know About

Used Labeling Machinery and Packaging Machinery:

Purchasing used labeling machinery, sealing, and packaging machinery will definitely provide a path to lower machinery purchase costs- and it will feel like a great deal. But watch out- you could be setting yourself up for huge costs that far outweigh any savings you thought you might make by purchasing second-hand.

There are many ‘unseen’ costs of purchasing used label application machines, sealing machines and other packaging machinery. This is especially the case with Labeling machines.

Consider Employee Skill Set Requirements

The skills required to operate older labelling* machines will far outway the skills to operate modern good value labeling equipment. Increased skill set employees means, increased training and dependence on higher paid more experienced staff to keep an old machine running (if you can find such staff – or keep them). Newer labeling machinery provides ease of use technology such as touch screen controls, motor speed synchronization and far more simple job changeovers; put simply new labeling equipment is usually far easier to operate. Setting up an old/used machine and teaching employees to properly use it can quickly eat into the “savings” you made buying the machine.

Machine Condition and Reliability

Reliability is a big factor. Although a machine may look like it is in good shape from the outside, used equipment is subject to previous wear and tear including items that might not be immediately visible. Even with a thorough manual inspection from a skilled technician, there are internal problems that can be missed. To name a few of the very likely things you will inherit; consider bent shafts, worn down gears and teeth, electronics on its last legs, obsolete operating systems and electronics and mechanical parts no longer produced.

Loss of production

The Big One: Loss of production TIME.
When production stalls your reputation, your profits and your business opportunities can all be significantly impacted.

Lengthy job set up times are NOT GOOD things; even if you have the advanced skill set employees to do them now. Compared to new labeling machines, most old machines have significantly longer and more complex set-up procedures.

Would you buy a car you could not service for all the likely AND unlikely service events? New and old machines alike come with the responsibility of maintenance. Maintenance of old equipment is a much more tricky affair that often involves long waits for replacement parts ; if you can find them or if they still exist. You may want to back yourself that you are qualified to self service an old labeler, however, labeling machines have a simple task that is achieved with literally thousands of parts. Even experienced label machine representatives and engineers call upon their teams to solve some issues – with your old labeling machine you are a team of one with a fraction of the labeling knowhow of a company that designs and supplies the current labeling machinery.

Good new labelling* equipment can be serviced quickly if a problem arises. “Current” parts are much faster and easier to identify, reorder and install.

Consider the enhanced position you are in if you were to order a good value LabelOn™ labeling machine with its online gallery support. Communicating any service issue is instant, recorded for future reference and identified using pictures and video of current machinery and parts (see below).

Label Machine Service - LabelOn™ Gallery Asset

Older labeling equipment may initially have a lower bottom line, but could really cost you in the long run. Current labeling machinery allows for ease of use, quicker training, assured service and support plus significantly fast job turn around.

Buying your labelling* machine, induction sealing machine and other packaging machinery can be a big decision, for your production process, its dependability and your pocketbook.

You really need to find great machinery; where you know it will work without breaking the bank or compromising the integrity of your production.

We have solutions:

We provide the options that fit your needs and your budget- you won’t be overspending here. We can provide consulting and testing before you purchase your label applicators, induction sealers, or other packaging machinery. We are confident that in most cases we present the best value production solution.

Breakthrough Glass Induction Sealing with SealerOn™

The Video Below, with SealerOn™ Breakthrough Glass Induction Sealing Material, demonstrates how easy it is to apply an induction seal onto a glass pack that is using a plastic lid.

Heat Shrink Bands

Heat Shrink Bands can often be a very user unfriendly part of packaging for products in Glass.

Clients purchasing products in Glass often do so with the thought that is it premium packaging preserving the purity of the product.

They can also expect there is environmental benefits as the packaging is easily identified and separated for recycling.
When faced with removing (with some difficulty) a super lightweight piece of unknown plastic (often PVC), it is clear this is a near transparent piece of plastic that could be even more devastating than plastic bags; perhaps the perfect “turtle (marine life) choker”.

On the production side of things, applying heat shrink bands can be a tricky and sometimes dangerous set-up. It involves high temperature heat guns, blowers or steam tunnels. It also involves dealing with a lightweight film in individual pieces or in tube form where consistent placement and finish can be very difficult.

Universal Induction Foils

For a long time, universal induction foils for glass have been available, however, they have proven to be effective mainly for dry products and powders. Wet or oily products can appear to be sealed by these universal foils, however, in time what looked like well sealed products end up having a foil that lifts off the sealing rim “on its own”.

Glass Induction Material

SealerOn™ breakthrough glass induction sealing material has been shown to work on wet products and oily products such as coconut oil.

At SealerOn™ we have solutions to seal glass with Plastic Caps and we even have solutions to Induction seal Glass that has metal caps!

Making Re-Purposed Glass Packaging Possible with Induction Sealing and SealerOn™

Induction Sealing Glass

The appeal to pack into glass is well documented.

Those seeking products in glass are looking for product that is not tainted by plastic contact. They are looking for purity in the product and most likely align themselves with the goals of environmental awareness and sustainability.

If packaging can be recycled, that is a big plus to these consumers. If packaging can be re-purposed or go on serve a purpose well beyond a single use, that is ideal.

Almost all Glass Packaging has a Neck with a thread to allow for the placement of a cap.

More often than not, the caps are Metal Caps and this tends to eliminate the prospect for sealing using induction sealing as the induction sealing process usually works with a cap holding the induction sealing liner and passing under a high frequency oscillating magnetic field; the metal caps do not allow this field to reach the induction material.

Food and Cosmetics packed into Glass need

a) A Good Barrier on their Opening.

b) A form of Tamper Evidence.

c) A seal that will not allow for leaking.

To achieve a) b) and c) traditional Secondary measures include:

i) Heat Shrink Bands (Some refer to these light weight transparent thin pieces of throw away plastic as potential “turtle chokers”)

The application of these Heat Shrink Bands is onerous in production

The removal of the Heat Shrink Bands is onerous on the end user

They are a great source of dust collection

They rely on other properties of the Cap and Capping Equipment to prevent leaking

ii) Tamper evident Labels applied to the lid with one or more fingers that fold down the sides of the container.

There is clever machinery out there to achieve this see: http://view.label-on.com/jarste

This method also relies on other properties of the Cap and Capping Equipment to prevent leaking.

With new “Break Though Glass Induction Sealing Material” and with a range of standard and Capless Induction Sealing machinery; Adeneli and Benefel can present new and innovative solutions to pack in glass.

To date Glass induction sealing material had been limited, in the main, to dry products such as instant coffee or Gel Capsules and other powders.

We now have a “Break Though Glass Induction Sealing Material” that works with many liquids including Vegetable based Oils.

Cap Liner Types and Functions

A cap liner is a piece of material that sits between the cap and the bottle. Its traditional primary purposes are to offer proper sealing of the product to prevent leakage and optionally to provide tamper evidence.

New technology is now turning this humble piece of packaging into a multimedia gateway for brands to reach out to their consumers through the Tribe Platform.

Since the cap liner is something only seen by the consumer after the product has been opened, the cap liner can essentially facilitate a “cap coupon”.

Tribe Example on Cap Liners

Since the cap liner is in direct contact with the product, chemical compatibility and correct certification for contact with your kind of product is crucial. Using the wrong seal can lead to expensive and sometimes dangerous mistakes that can jeopardize your product brand and integrity.

Chemical products and consumer/food products can require liners that differ significantly in their properties. The varying liner materials have different jobs. They may be used as any combination of moisture barriers, oxygen barriers, chemical resistant barriers, consumer tamper evidence safety and for preventing leakage.

The cap liner material alone can significantly affect the cost of the cap, not to mention the impact on the finished product.

Compatibility of the caps, liners and bottles has to be tested; as well as the compatibility of these packaging materials to the product inside.

Selecting the Right Seal

Novice producers may find it difficult to decide which cap liner is the right solution for their product. With all the different liner types available, choosing the correct liner for your product and container is an important step. If considering cap lining material it may be worthwhile looking at how a practical packaging initiative and a practical marketing initiative can be combined.

A wide range of cap seals are available but by focusing on these key questions, we should be able to narrow down the field:

Level of tamper evidence required?
Type of product: liquid, powder, or solid?
After opening the product is a reseal important?
Will the Seal be used to promote the Brand?

Some Popular Cap Liners

Plain Expanded PE foam. Providing both a seal and reseal, this is one of the lowest cost cap lining materials available. When produced using C02 Gas the cell structure of this material can be tight and present and perform close to that of some laminated foams produced with less sophisticated methods.

Laminated Expanded PE foam. As per the Plain foam this material has added layers often on both sides to provide a smoother and more chemically resistant sealing surface. With the right laminates this material can have Good resistance to acid, alkalis, solvents, alcohols, oils, household cosmetics, and aqueous products. Aluminum, Tin or Saran are common coatings used for alcohol with Tin being particularly popular for Wine bottles with screw caps.

Pressure Seal Foam Liner. Coated with torque-activated adhesive, the action of applying the cap causes this seal to bond with the bottle or product opening; there is no need for an outside heat source. Historically this type of seal was applied to provide tamper evidence and often printed with words that would infer that the seal was a form of tamper evidence. You will now notice that on any credible supplier’s specification sheet they will go out of their way to state this is NOT a seal to provide tamper evidence. This is to avoid potential legal claims associated with the possibility this type of seal can be tampered with and reapplied without any special equipment. The Moisture and oxygen barrier of this type of material is also generally lower than laminated foams.

Induction Liners – When passed through an induction process, the foil layer heats up in a process that will bond all or part of the lining material to the top of the product. Induction liners can only be applied using an Induction Sealing Machine.

There are 2 types of Induction Liners:

One-piece Foil. Since it “sticks” to the bottle after sealing, this single-use foil is one of the most common forms of sealing. Side tabs and Lift ‘n’ Peel™ options add to the experience of easy removal from the lid for items like milk and juices. An added barrier layer can also provide protection against aggressive products. An air and watertight hermetic seal prevents leakage in packaging for edible oils, water, juices, condiments, shampoos & conditioners, gasoline treatments, additives, food & beverages, nutraceutical products, health & beauty products, vitamins, spices, and pharmaceutical products. Often a one piece Foil will need to be applied over a softer and thicker foam based liner to insure a good distribution of pressure from the cap over the entire opening of the product to be sealed.

Two-piece Heat Induction Liner – The benefit of using two-piece heat induction liners is that they eliminate the need for lining the closure in two separate stages: The base foam or cardboard layer of the liner is temporarily bonded to the foil with either a wax and paper layer or a separating polymer layer.
