Cap Lining Materials and Induction Sealing Machines

Induction Sealing Machines

Induction Sealing

    The induction sealing process allows containers to be sealed without the use of bands and plastics. This is unlike traditional glass sealing practices. The use of induction sealing has revolutionized packaging as it solved the issue that many manufacturers used to face when it came to sealing their goods. 

    In the past, manufacturers and distributors had a difficult time trying to package oils, seasonings and various liquids as they, moreInduction Seal Two Piece Liner Precut often than not, ended up leaking during transport. With the advent of two-piece liner induction seals, even these notorious products can now be packaged without worrying about the integrity of the seals.

The Cap Lining Process

    The process of packaging goods begins with the container caps. The caps are supplied with induction liners. On the production line, the containers are filled and capped. The capped container travels through the conveyor and ends up below the appropriate induction sealing head. This sealing head generates an electromagnetic field that penetrates the cap and the induction sealing foil layer within. The electric current produced will melt the sealing film in the liner. Once the foil has cooled down, the heated sealing film will form a strong bond to the mouth of the container, staying there until the consumer removes the induction liner. 

Cap Liner Types

    There are generally two types of cap liners. These two categories are differentiated by their components and the subsequent functions they serve. 

    All cap liners function to keep the contents of the container fresh by serving as a barrier against moisture and oxygen level fluctuations. The induction sealing foils can also be used as tamper evidence for the consumer’s safety. However, even if liners in general serve these purposes, it is still important to know which type of liner to use for your product.

    One-piece cap liners are designed to be adequate freshness seals up until the packaging is opened and the liner removed and discarded. Generally, these types of induction seal liners are for one-use types of products, such as those contained in smaller bottles and products which need to be used up soon after opening. 

    Two-piece cap liners also provide a freshness seal and tamper evidence, but unlike the one-piece type, these liners leave a portion of the liner material within the cap. This means that even though part of the liner is removed once the packaging is opened, the product can still be resealed and kept fresh even after multiple uses. This type of induction seal is useful for bigger containers and when the consumer is expected to use the product for a longer period of time.

Liner Material Types and Functions

Liner Material Functions

Liner material sits between a cap and the bottle. They are traditionally used for their ability as adequate seals for bottles, lining material that prevents leakage, and optionally to provide a form of tamper evidence.

When thinking of the type of liner material you will need for your product, chemical compatibility and correct certification for contact with the product is crucial. Using the wrong liner material can lead to expensive and sometimes life-endangering mistakes that can jeopardize your product brand and integrity. 

Chemical products and consumer/food products can require liners that differ significantly in their properties. Depending on the job these liners have to comply with, the variety in liner materials can be extensive and choosing what fits your product best can be a daunting task. 

Generally, functions that liners have to carry out can be any combination of the following:

  • Moisture barriers
  • Oxygen barriers
  • Chemical-resistant barriers
  • Consumer tamper evidence safety
  • Leakage prevention

    The compatibility of the caps, liners and the containers with one another has to be tested, along with the components’ compatibility with the product inside.

With these numerous considerations, the liner material alone can significantly affect the cost of the cap and the rest of the production line. As such, it is important to know which liner is ideal for your setup. 

Selecting The Right Type

    Among the wide range of lining material available, choosing the appropriate one for your product can be narrowed down with the following key questions. 

  • What type of product is it: liquid, powder or solid?
  • What level of tamper evidence is required?
  • Once opened, is resealing the product for freshness required?
  • Will the liner material be used to promote the brand?

Liner Material Based on Components

    There are two general types of heat induction liner based on their components:

This type of lining material is used more often for one-use products. They are more suited for dry products because these usually need less protection and may not need a freshness seal once the package has been opened. 

Induction Seal Two Piece Liner PrecutThe lining “sticks” to the bottle after sealing and is one of the most common forms of sealing. Examples of this type include side tabs and lift’n’peel options. 

Although this type is used more often for dry products, there are ways to utilize this liner for other purposes. Adding a barrier layer can provide protection against aggressive products. An air and watertight hermetic seal can prevent leakage in the packaging of a wider variety of products including food and beverages, cosmetics, and pharmaceuticals.

The two-piece liner type can also do what the one-piece liner can, but it has its own additional advantages. One application is for resealing a container once it has been opened. This liner material is appropriate for when freshness of the product must be kept in mind. This resealing ability is necessary for many products particularly in the food industry. 

    Both of these liner materials are capable of the fundamental functions of lining material, including prevention of leakage, prolonging the product’s shelf-life, serving as a barrier against moisture and oxygen, and providing proof of tampering. Choosing which type is more applicable for your own production line will depend on what function you will need your liner to do.

    Cap liners are materials found nestled between the cap and the mouth of the container. In many industries, one can easily spot these cap liners, solidifying the idea that having cap liners is integral in keeping up with the ever-increasing global demand for products. As such, having the suitable lining machinery to meet production needs is imperative for any business looking to branch out and increase revenue. 

liner insertion machine    Applications for these cap lining machines are set across the board. In general, lining machines punch the cap liners within the caps of the containers, ensuring a tight fit. This is why another term for lining machinery is “cap liner insertion machines.” With more and more industries finding needs for cap liners, these lining machines have increased in demand and can now be found in a wide range of businesses. 

    Cap liners are widely used in the food and beverage industry. Without these induction seals, importation and exportation of goods cannot be attained without significant losses on both the producer and the consumer sides. Seals for bottles keep the product fresh by minimizing fluctuations in oxygen and moisture levels and prevent leaks through the tight seal they provide—an important aspect when it comes to the handling and transporting of goods. Another important function of cap liners is the tamper evidence they are able to provide for consumers. This specific function keeps consumers safe from any disruption of the product while also keeping the public’s trust towards manufacturers and distributors.

tamper evident seal    Another field wherein induction seals are applied is in pharmaceuticals. When it comes to tamper-evident seals, pharmaceutical products are foremost because any tampering with such products can be catastrophic both for the consumer and the manufacturer. This importance is highlighted by the Food and Drug Administration’s (FDA) emphasis and guidelines on the use of tamper evidence in manufacturers’ products in order to protect the health of the public. 

    Besides these giant users of cap liners, a wide array of goods in the cosmetics industry also benefit from this technology. With cap liners’ additional use in keeping the production and end-user process more sanitary, these seals for bottles  are a crucial part of any cosmetic product in the modern world. 

    One other field which many people deem cap liners to be an imperative part of, is the agriculture sector. Solvents and a wide array of chemicals can be highly corrosive and dangerous when tampered with. These substances can be contained and stored properly with the use of certain specific cap liners which can withstand the abrasive and corrosive nature of these products. In this case, the public is protected from spills and leaks, helping keep consumers safe. 

    The varied applications in different industries brought about by cap liners cannot be undermined. Having the appropriate liner machine to meet your product’s needs is vital to keep said product alive in the current globally competitive market. 

The Induction Sealing Process

    Induction sealing is the process by which the cap lining material is adhered onto the mouth of the container, creating a hermetic seal to keep in freshness and to keep out excess oxygen and moisture. The process makes use of lining machinery that can cope with the rigors of the production line. These machines must be efficient without sacrificing accuracy and precision.

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.
