Tamper Evidence Seal

    Product seals have different applications in the multiple fields they are utilized in. The most basic functions of cap liners include maintaining a product’s shelf-life by serving as a barrier against oxygen and moisture from the surroundings, preventing any leakage through proper adherence either on the mouth of the container or within the cap, keeping the product fresh and unaffected during transportation and handling, and providing additional branding benefits through the cap liner label. But one aspect which may be overlooked is that these products also come with the label of “sealed for protection.”

    This seal is the manufacturer’s answer to the issue of product tampering. Product seals come with this label because it announces to the consumer that the product has tamper evidence technology, effectively safeguarding the consumer from any outside disruption to their product. 

Peels and Seals as Tamper Evidence

    The Food and Drug Administration (FDA) has made clear guidelines for manufacturers and distributors regarding their product seals. Through the FDA’s attempt at regulating the approach of manufacturers with how they show product tampering, the public is now aware of the importance of the “sealed for protection” liner approach.

    Any breach in the product seal is easily demonstrable through this method and the consumer is alerted of any incidents of tampering. This greatly elevates the public’s safety against any damage or disruption to the products they consume. 

    In the pharmaceutical industry, tamper evidence is demonstrated through the cap liners in containers, showing a “peel and seal” approach in that once the consumer opens the product, they are shown an intact, multilayered seal whose upper part they can remove and discard. The remaining part can then be replaced within the cap of the container, thereby protecting the product from moisture or oxygen exposure for the remainder of its shelf-life. 

    For food products and beverages, the “sealed for protection” cap liners are equally important. Providing the public these cap liners as a means for protection boosts the people’s trust towards the manufacturers of the products they consume.

Induction Sealing Process for “Sealed for Protection” Packaging

    In order to give the best possible results for product sealing, production must both be monitored from the start, and end with a good, reliable induction sealing methodology. 

Induction sealing entails a series of steps to ultimately facilitate adherence of the product seal onto the mouth of the container. The cap and its corresponding liner arrive at the production line. Along with the already-filled container, these components move down the line until they reach the induction sealing head. This part generates an electromagnetic field which can pass through the cap and into the aluminum layer found within the liner. This permeation melts the liner and seals the product within. This hermetic seal is then allowed to cool while the container continues to move down the production line. 

    The great advantage of induction-sealed containers is that the liners themselves, while being resilient in their own composition, cannot be reattached once removed from the container mouth. That is, anyone who decides to tamper with said container will need specialized product sealing equipment to reattach the liner onto the container. Therefore, this form of “sealed for protection” packaging is a very reliable way of protecting the product and subsequently, the consumers.

Peels and Seals Liners

    Manufacturers have to be aware of how product sealing can impact consumers. “Seal For Your Protection” Packaging is widely utilized in different fields, employing product seals that can deliver both the required safety elements for the consumer while giving them the satisfaction of a well-made product. 

    When it comes to tamper-evident seals, any form of disruption on the liner can be a sign to the consumer of any untoward tampering. Consumers then choose to either discard the product or report the issue to the proper authorities, especially when it comes to pharmaceuticals’ tampering. 

    In the pharmaceutical industry, “seal for your protection” packaging, otherwise known as tamper-evident packaging, is prominent. So much so that even the Food and Drug Administration (FDA) has strict protocols that manufacturers must adhere to, in order to protect the safety of the public. The FDA has defined this type of packaging as “one having one or more indicators or barriers to entry which, if breached or missing, can reasonably be expected to provide visible evidence to consumers that tampering has occurred.” Strict requirements are imposed on manufacturers and distributors of pharmaceuticals in the interest of the people. 

    Besides the pharmaceutical industry, the food and beverage industry also benefit from the “seal for your protection” packaging. Not only do the cap liners found in these foods’ containers serve as freshness seals, but they also allow for any evidence of package disruption by an outside force. 

Product Sealing and Cap Liners

    Cap liners serve four basic functions:

• Protect against fluctuations in moisture and oxygen exposure of the product
• Prevent product leakage during transportation and handling
• Preserve the product’s freshness and maintain its shelf-life
• Provide evidence of any tampering of the product

    In general, product seals can be classified into one- or two-piece liners. These two vary in their composition and applications.

    One-piece liners are more often used on dry goods and powders and are applicable for one-time use packaging. Products which benefit from this type of cap liner include those expected to be consumed immediately upon opening.

    Two-piece liners, on the other hand, are more commonly utilized for liquids and products meant to be opened and reused multiple times over an extended period of time. These liners are not discarded on opening of the product and instead reside within the cap of the container in order to maintain the container’s leak-proofing and preserve the product’s shelf-life.

    Both types of cap liners have their own advantages. Whichever type of product seal you choose for your product, both types must undergo the induction sealing process in order to adhere onto the mouth of the container. 

Induction Sealing For “Peels and Seals”

     In the induction sealing process, a cap with its respective liner comes into the conveyor line. The filled container is paired with the cap, and both make their way down the production line until they reach the induction sealing head. This induction sealing head is able to emit an electromagnetic field which can permeate both the cap and the aluminum foil layer within the liner. The electric current generated is able to melt the liner film, allowing for adherence of the liner onto the container mouth. The liner is then allowed to cool as it makes its way down the next part of the conveyor line. 

No matter the type of cap liner, it is imperative that the seal be adequate in doing its job in order to not jeopardize the trust of the consumer with the product. With the induction sealing process, the liners are able to do their jobs of sealing in freshness while keeping tampering at bay.
