Cap Lining Materials and Induction Sealing Machines

Foam Liners Foil Seals for Bottles

Freshness Seals in Container Packaging

    Over the years, foam liners have found increased usage in many fields. As cap lining materials, these products maintain the integrity of a product by preventing exposure to oxygen and moisture from the environment. They also keep the contents from leaks and mishaps especially during transportation and handling. Foam liners, along with other types of cap liners also allow for tamper evidence by demonstrating proof of any disruption in the product barrier. 

Types of Foam Liners

    Due to the varied needs presented by different industries, there are a myriad of cap liners to choose from. What makes choosing the perfect type for your product are the considerations with the material of the liner itself and how compatible the liner is with your product. Depending on what product you aim to produce, there may be additional guidelines to be met such as for the food and beverage industry, as well as for pharmaceuticals. The Food and Drug Administration (FDA) has set guidelines for liners to be used with these products in order to protect the wellbeing of the consumers. 

    In general, cap liners are composed of a laminate of material which are induction sealed onto the mouths of the containers. The cap liners, once adhered onto the container mouth, cannot be reattached without special machinery, so any disruption in this seal can can alert the consumer if any tampering has been performed on the purchased product. Induction Seals One Piece

    As mentioned earlier, there are different liners which cater to different needs of the manufacturer. Broadly, liners can be divided into one- or two-piece liners. One-piece liners are mainly used for dry products and powders. Before opening, these act as freshness seals and maintain the product’s shelf-life. Once opened, the seal is usually discarded. As such, this type of liners are designated as single-use liners. 

Induction Seal Two Piece Liner Precut    The second type is the two-piece liner. These liners differ in that they can be used to reseal the container many times from the initial opening. These liners are better suited for products intended for use over an extended period of time. The two-piece liner is also used for liquids such as oils and seasonings as they are more resilient and leak-proof than their one-piece counterparts. 


Foil Induction Seals as Cap Lining Material

    Foam liners are used in many fields of manufacturing and packaging. These versatile liners are great as freshness seals and are more economical than other types of cap liners. You can choose between the one- or two-piece type to cater to both simpler products or those with more complex requirements.

    These foam liners typically form part of the cap lining material. When the container is opened, the seal is initially disrupted and removed. The foam liner can then be replaced within the cap of the container, serving its purpose of keeping the product fresh and preventing leaks from occurring. 

    The advantages of foam liners are found in their resilience against many chemicals and that they do not disintegrate easily. They are good for many types of solvents and can resist chemical abrasion from alkalis and acids. They also provide sufficient leakage protection for liquid products, hence they are used for seasonings and oils. Foam liners are also used for the pharmaceutical and cosmetics industries, acting as freshness seals for many products.

Foam Liner Freshness Seal

Foil Induction Seals in Caps

    Cap liners are safeguards that keep your product fresher for longer by keeping moisture and oxygen fluctuations at bay. The freshness seals are typically found adhered onto the container mouth through induction sealing or within the cap itself such as in cases of foam liner seals. In some instances, cap liners may come in both configurations within the same container. 

    There are a myriad of cap liners to choose from, all with different applications depending on multiple factors. In order to choose the perfect type for your needs, it is imperative to know the different types of cap liners and what they are composed of. 

    Cap liners are made of laminates of material which pass through the process of induction sealing in order to adhere them to the mouths of the containers. In terms of applications of these foilseals, they may be classified as one- or two-piece liners. 

   One-piece liners are adhered to the container mouth and are removed on the initial opening of the product. These foil seals for bottles are ideal for one-time use and are often discarded after the first opening. This means that it does not come with a guarantee of resealing the product’s freshness once the packaging has been opened. These types of liners are usually used for dried goods and powders as well as types of products expected to be consumed immediately after opening.

    Two-piece liners, on the other hand, can reseal the product because they are not discarded immediately after use. Once the packaging is opened, these foil induction seals retain their use. They are typically used for products which need to be opened repeatedly over a prolonged period of time. This type of capliners can be used for liquids and oils and serve as a better barrier against the elements from the outside, as well as providing the container leak-proofing. 

Foam Liners in Packaging

  Induction Seal Two Piece Liner Precut  Foam liners can come in either the one- or two-piece type. In general, foam liners stay within the cap in order to adequately seal in the product. They are used in a variety of fields such as for the food and beverage industry, pharmaceuticals, industrial chemicals and even cosmetics. 

    Foam liners are a more economical option compared to other types of liners and do offer up their own set of advantages. The foam is able to withstand chemical abrasion such as when exposed to acids and alkalis or even some solvents. Foam liners are also a good material for a variety of liquids such as oils and seasonings—liquids which usually stump other types of foilseal liners when trying to maintain their integrity for prolonged periods of time. 

    These freshness seals are also compatible with a wide range of products and may be perfect for your product as well. 

Foil Seals For Bottles in The Induction Sealing Process

   induction sealing process For liners to adhere sufficiently onto the container mouth, the induction sealing process is employed, utilizing specialized equipment able to meet the demands of large-scale production. Caps come in with the foam liner. Along with the already-filled product container, they make their way down the conveyor line until they reach the induction sealing head. This head emits an electromagnetic field which permeates through the cap. This field generates enough of an electric current in order to melt the film within the liner and adhere it onto the mouth of the container. 

    Once the consumer opens the container, they can remove the seal and place it inside of the cap so the foam liner can do its job of keeping in the freshness and preventing leakage of the product.

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.
