Cap Lining Materials and Induction Sealing Machines

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. 

Induction Seals One Piece    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.Induction Seal Two Piece Liner Precut

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.

Sealing Containers through The Induction Sealing Process

    These days, when it comes to sealing containers in any industry, nothing beats cap liners. These are the materials found sandwiched between the cap and the mouth of the container, forming a barrier between the contents therein and the outside world. 

glass jar seal    In a variety of businesses, these cap liners are imperative for sealing containers. It boasts a way by which international importation and exportation of goods can be achieved because it keeps the integrity of products while allowing for the rigors of handling and transportation. Without this technology, progress and innovation will be greatly impeded on an international level. 

    The importance of sealing containers through the use of cap liners cannot be overstated. A multitude of industries utilize these liners for the benefit of their consumers. 

    One of the foremost users of cap liners is the food and beverage industry. Cap liners serve to keep the product’s freshness by mitigating exposure to oxygen and moisture levels. Sealed Packaging thus proves to be important during transport and handling of said product. These liners also provide a means of tamper evidence, allaying the consumers’ fears of any untoward disruption of their purchase.

    The use of tamper evidence is even more apparent in the pharmaceutical industry. Issues with tampering can be difficult to manage without cap liners because these serve as a safety tool for consumers. Therefore, any question in the minds of the people with regards to product integrity can spell disaster for the manufacturer. The importance is even more highlighted by the Food and Drug Administration’s guidelines and implementation of the use of tamper-evident seals for public safety. 

    Aside from these industries, a wide array of other companies make use of cap liners for sealing containers including cosmetics, agriculture and even petrol.

MeRo Induction Machines and Induction Sealing

    The innovation that is induction sealing is a growing enterprise. It has paved the way for progress in many fields. One of themero specialty caps leading induction sealing machine businesses—MeRo—makes use of induction sealing and along them, many other operations do as well. 

    Induction sealing is the process by which cap liners are adhered onto the container. It begins with the cap and the liner inserted within it, coming into the production line. These components, along with the container already filled with the product, will go down the conveyor belt until they reach the induction sealing head. This part of the machine will then produce an electromagnetic field that can permeate the cap and the aluminum foil within it. This field will then generate an electric current which can melt part of the liner, adhering it firmly onto the mouth of the container. The container is then allowed to cool as it goes down the production line. 

    The use of induction sealing in sealing containers is trusted by consumers because of its time-proven reliability. It is able to keep the shelf-life of the product (and in some cases, extend it), while preventing leakage. It protects the product against moisture and oxygen changes in the environment and provides proof of tampering not easily achieved by other technology. With this innovation, industries are able to provide more products to more people internationally.

Glass Jar Seal and Glass Induction Sealing with SealerOn™

Traditional glass jar seal techniques no longer cut it when it comes to the average consumer’s needs. More and more people value a product’s longevity through the provision of reliable oxygen and moisture barrier. Along with this is the necessity for tamper evidence, particularly for products such as food and pharmaceuticals. And for the benefit of everyone involved in the process of product procurement, all the way to consumption of the said product, a leak-proof approach is more than necessary. 

In the past, glass jar seals were often quite unreliable. Consumers faced the dilemma of sub-par seals or foil seals that made it too difficult to get to the product itself. For the part of the manufacturer, the process of adhesion of the seals onto the glass containers was very daunting and more often than not, ended up with inadequate results. Manufacturers were forced to rely on heat shrink bands to achieve a seal that kept the product within the container but these bands were too finicky for consumers to remove. These issues have now been remedied, thanks to glass jar sealing technology. 

Many consumers prefer to purchase products in glass jars. They often do so with the thought that glass is more premium packaging over plastics as the glass is viewed to preserve the “purity” of the product. They also rely on this packaging to be of more environmental benefit and can easily be separated for recycling. As such, the need to make our customers’ lives easier is a foremost demand in almost any industry.

 

Primitive Glass Bottle Sealing

Shrink Film as Tamper Evident Seal

Older technology for sealing glass jars made use of heat shrink bands and unreliable universal induction foils. 

Heat shrink bands can be a fickle tool to use. On the production side of things, applying heat shrink bands onto the glass jar can be a tricky and sometimes dangerous setup. It involves high-temperature heat guns, blowers, or steam tunnels. It also deals with a lightweight film that could come either in individual pieces or in tube form. This film format necessitates consistent placement and finishes which can be arduous to have to meet each time. 

For clients, heat shrink bands can bring a very unfriendly user experience. These bands are difficult to remove. And with the idea in the consumers’ minds that “glass = good for the environment,” having to remove a piece of transparent PVC plastic the very first moment they need to use the product, can be quite off-putting. 

On the other hand, some manufacturers decided to use universal induction foils for glass sealing. Even at the time, these induction foils for glass had already been available for a long while. However, this technology proved to be effective mainly for dry products and powders only. Wet or oily products can initially appear to be sealed with said foils, but over time, what looked like well-sealed products ended up having a foil that lifted off the sealing rim “on its own.”

Now, in a time when consumers value good quality and trust in the products they use, having foil seals for bottles that detach themselves from the glass jar can be detrimental to sales.
