Cap Lining Machine: How to Insert Induction Seals in Caps
Cap Lining Materials
Cap lining materials are inserted into the caps or closures of containers being supplied for use in the packaging process. These liners offer multiple benefits, such as leak-proofing the container, maintaining adequate oxygen and moisture within the container so as to prolong the product’s shelf-life, and serving as tamper evidence in case of product disruption.
Specialized cap lining machinery is needed to place these cap lining materials. For cap manufacturers especially, having machines for this purpose is vital. Some end users may also benefit from investing in such machines when the demand for their product reaches more than 10,000 lined caps per day.
There are a multitude of industries which make use of cap liners. Food industries in the 21st century cannot do without cap wad insert machine because the rigors of transport, handling and distribution could adversely impact the products. Coffee, wine and other beverage manufacturers and distributors are common users of these cap lining materials. Cosmetics also use them both for sanitary reasons and to keep the product’s shelf-life.
In the field of pharmaceuticals, cap lining materials are also of utmost importance. Tamper evidence can be provided in an economical and consumer-friendly manner without compromising the integrity of the product in the process. Its significance is even highlighted by the Food and Drug Administration’s (FDA) guidelines in the use of such materials for the safety of the public.
Agricultural chemicals also use an assortment of cap lining materials. Certain types of liners are applicable for solvents, alkalis and acids, making them ideal for these hazardous substances.
The Induction Sealing Process
In order to adhere the cap liners onto the containers, cap lining machines will introduce the containers to the induction sealing process.
Induction sealing begins with the cap and its associated liner arriving to the production line. The liner is placed within the cap and, along with the filled container, will go down the conveyor line until the components reach the induction sealing head. This part of the machine will introduce an electromagnetic field which can permeate the cap and the aluminum layer within the liner. This field will then generate enough electric current to melt part of the liner, effectively adhering it onto the mouth of the container. The container is then allowed to cool down as it continues its way down the conveyor belt.
The impressive thing about the induction sealing process is that, once the container reaches the consumer and the liner is removed, it cannot be reattached onto the container without specialized cap liner insertion machines.Lining Machinery and Cap Liners Supplier This provides another level of tamper evidence for the benefit of the consumer.
Choice of Cap Liner Machinery
Cap lining material can be supplied in either a pre-cut or roll format. Choosing between these options will depend on the scale of the project and the budget for equipment, with many options and outcomes available. For the smallest and the largest of cap lining projects, there are pre-cut cap liner machine options which can meet the demands of production, while being the more economical option for the manufacturer. For medium to large scale operations, roll-form lining machines are available.
Sometimes however, the choice of machinery will depend on a particular project and its lining requirements. Certain specifications and processes may need to be met for these projects, and so, reaching out to our team can help you find the best machine and cap liner for your product.

Heat Induction Seals | Capless
Capless Heat Induction Seals
Heat induction seals are cap lining materials found between the cap and the mouth of the container. These heat seals keep the freshness of the product by keeping moisture and oxygen from infiltrating the product. They act to prolong the product’s shelf-life and prevent any leakage. An added benefit is the tamper evidence provided by induction foil sealing in order to protect the consumers from any outside disruption.
Many industries make use of heat induction seals. Food and beverage industries are some of the foremost users because with the globalization of exportation and importation of their products, manufacturing and distribution could possible disrupt product integrity at any point in the process. Any issues during handling can lead to catastrophic results for both the manufacturer and distributor, and so, having heat induction seals to protect these products are a lifesaver.
In the pharmaceutical industry, induction seal liners are also of utmost importance. For these kinds of products, the need for adequate tamperproofing and tamper-evidence cannot be overstated. The heat seals are so important that the Food and Drug Administration (FDA) even has set guidelines for tamper-evident seals, all for the benefit of the consumer.
Other industries also make full use of induction seal liners. For cosmetics, heat induction seals help preserve freshness of the product while also keeping the processing of the cosmetics sanitary. In agriculture, chemicals which were once difficult to contain safely, are now easily contained and distributed. Certain types of induction seal caps are capable of withstanding the abrasive properties of chemicals, thereby allowing for proper sealing of these materials.
The Induction Sealing Process
Heat induction sealing begins with the acquisition of the caps and their associated liners. These caps make their way to the production line and, along with the already-filled containers, continue through the conveyor belt until they reach the heat induction sealing head. This component generates an electromagnetic field which can permeate the cap and the aluminum foil layer found within the induction liner. The field is able to generate enough of an electric current to melt the part of the liner in contact with the mouth of the container, effectively sealing the product and preventing any contamination of the products therein. The container then cools down as it continues down the line.
Key Benefits to Induction Sealing From Benefel Pty Ltd. and Adeneli Packaging
- The sealing process can lessen incidence of product contamination at any point in the production chain.
- Heat induction sealing can add significantly more force when pressing the liner onto the container opening than what conventional induction sealing can provide. This results in a much better and more even contact of the liner.
- 100% visual inspection of the heat induction seal for quality assurance purposes is possible.
- On request, the seal integrity can be increased even more by dead-folding the edges of the seal around the lip of the container.
- Heat induction sealing can eliminate the need for multi-layer cap lining or a separate foam liner placed in the cap.
- Dust issues associated with multi-layer cap lining material can be eliminated with the use of heat induction sealing instead.
- Direct purchase of the cap lining material means that there are no markups or extra charges on your end.
- We can organize for your own logo or print message to be placed onto the heat induction seal, all at a very competitive price.

Sealing Glass Jars with Metal Lids
Sealing Glass Jars through Capless Induction Sealing
When it comes to sealing glass jars, specifically those with metal lids, a big hurdle is adequate sealing. In the past, this task was insurmountable, and for many years, the induction sealing process was limited to plastic containers with plastic caps. These days, with the introduction of more wattage in better-functioning equipment, sealing glass jars is possible with capless induction sealing.
This type of process allows seals to be leak-proof, making handling and transportation of said products easier on everyone involved. The induction seals are hermetically generated and are able to prevent the products from being affected by outside moisture and oxygen fluctuations. This keeps the contents fresh for longer, able to meet and even extend the shelf-life of the product. An added advantage is its tamper evidence. The nature of the seal itself allows for any disruption to be easily noticed, for the benefit of the consumer.
These aspects are time-tested and proven advantages of induction sealing. As such, the public puts their trust towards these products. And now, with the innovation of capless induction sealing of glass jars, more and more avenues are being opened up for different industries.
Sealing Products with Metal Lids
When product manufacturers choose to use metal lids instead of the more conventional plastic type, the induction process must be adapted to suit their needs. The classic induction process finds its liners inserted within the cap of the container. These components pass under an induction sealing head which generates an electromagnetic field which can permeate the cap of the container without damaging it. This field generates enough electric current to melt part of the liner, adhering it firmly onto the mouth of the container. The now-capped container then cools as it makes its way down the conveyor belt.
The downside of the traditional induction sealing process is that it cannot be used when the container comes with a metal lid. This is why these types of containers require a special mode of induction sealing process.
Through capless induction sealing, this problem has been remedied. An additional component is added to the equipment in order to apply the necessary pressure onto the liner while it is being adhered on the lip of the container. These additional sealing heads may come in different configurations, e.g., single or multiple heads. The sealing head is able to generate enough heat and pressure to adequately seal the container even without a cap.
Through this technology, as with induction sealing in general, many industries have branched out into international trades and commerce. The food and beverage industry is a foremost user of cap liners because of the freshness guarantee that comes with these products. The prolonged shelf-life also allows for international export without the issue of spoilage or leaks.
Another industry that makes full utilization of induction liners is the pharmaceutical industry. With the necessity of tamper evidence in mind, these seals are invaluable in packaging for these companies. 
In the cosmetics industry, having properly sealed glass jars are not just for aesthetics, but also serve to prevent product contamination and help with handling of the products.
In the agricultural sector, these seals allow for containment of corrosive substances such as alkalis, acids and solvents, without compromising the safety of consumers.

Sealing Seals Induction Material Liner
Sealing Seals Through Induction Sealing
Induction material liners are laminated components found on the inside of container caps which serve a variety of functions as sealing seals. These liners are known by many names, including induction foils, induction sealing material, foil seals and induction seals. Products with this type of sealed packaging are trusted by the public because they keep the freshness of the product within and provide proof for any tampering of the product by outside forces. These two aspects boost the people’s confidence about the product and subsequently, the product manufacturers.
In the food and beverage and pharmaceutical industries, these sealing seals are vital and to some extent, required to ensure the safety of the consumers.
Sealing Product Purposes
The induction material liners within caps can be made as one- or two-piece components. Choosing which type to utilize depends on the expected purpose of the sealing seal.
Within smaller-sized containers, one usually finds one-piece cap liners. These products are more likely to be consumed soon after opening, therefore, these types of packaging are regarded as being one-time use. In this instance, the sealing seal functions as protection until the product is opened and no other material is left on the inside of the cap.
On the other hand, larger packs or bottled items are not likely to be completely consumed right after opening. The consumer is anticipated to reclose the container and store the product. The caps used for these conditions have demands for liners that reseal effectively. Upon close examination, the caps used on these kinds of merchandise have laminated foam within. This lamination enables the cap to reseal the container upon closing to maintain product freshness. When the container is first opened, the consumer will first find (and remove) the tamper-evident seal on the product. What will then remain is the lamination within the cap. These two components are what compose two-piece cap liners.
Which Sealing Seal to Choose
Deciding on the best components and structure of your foil seal is essential to guarantee the proper amount of protection for your merchandise. There are many variants which can fulfill almost any requirement for standard or individualized product packaging. These seals must be proven safe and meet the strict specifications set by the Food and Drug Administration to safeguard the public.
As such, sealing containers must meet basic functions in that they must be kept free from contamination, oxidation and moisture and that these hermetic seals be tamper-evident. These sealing seals will then be best suited for use in the following productions and many others:
- Food and Beverage
- Pharmaceuticals
- Acids and Alkalis
- Oils
- Organic solvents and products
- Flammables
- Powders
- Pellets
Sealing Products through The Induction Sealing Process
The induction sealing process adheres the seals onto the container mouths. The caps are supplied with an induction foil waiting to load into the capper. The container is then filled and capped.
The capped container is then transported down the conveyor line and travels underneath the induction sealing head. The electromagnetic field generated by the sealing head penetrates the cap and the aluminum foil layer. When this field permeates the foil, it causes an electric current which melts the liner’s sealing film. The foil cools down as it leaves the induction field, causing the heat seal film to bond to the container mouth. Once the cap is removed, the aluminum foil remains bonded to the lip of the container.
