Corefilm and Overlay Materials for Secure Card Applications

In an increasingly digital world, where data breaches and identity theft are common concerns, the importance of secure, tamper-proof identification cards cannot be overstated.

Card manufacturers and issuers are continually seeking materials that can withstand the test of time, harsh environmental conditions, and, most importantly, unauthorized access.

Two key components in the production of secure cards are Corefilm and Overlay.

Corefilm: The Backbone of Secure Cards

Corefilm is a rigid card material known for its opaque, high impact resistance and excellent lamination properties.

These features make it an ideal choice for a wide range of card applications, whether you’re producing low-end or high-end volume cards.

Its essential properties are:

1. Opacity: The opaqueness of Corefilm ensures that the information on the card remains confidential and secure. It prevents any attempts to read the card from the outside.
2. High Impact Resistance: Corefilm is designed to withstand physical wear and tear. This makes it a suitable choice for cards that are handled frequently, such as member cards and security cards.
3. Lamination Property: The lamination property of Corefilm ensures a strong bond between different layers of the card. This enhances the card’s durability and makes it less susceptible to tampering.

Applications of Corefilm:

1. Member Cards: Corefilm is an excellent choice for member cards, providing a secure and long-lasting solution for loyalty programs and memberships.
2. Telecom Cards: With its high impact resistance, Corefilm is ideal for telecom cards that need to endure rough handling in various environments.
3. Security Cards: For applications where security is paramount, such as access control or identification badges, Corefilm provides the necessary protection and confidentiality.

Overlay: Enhancing Security through Adhesion

The Overlay, a critical component in secure card production, serves to enhance the card’s security features.

It boasts high adhesion properties, ensuring maximum security for laminated cards.

Integral part of the security card manufacturing process are:

1. High Adhesion Properties: The Overlay material has a strong adhesive quality, making it difficult for counterfeiters to tamper with or remove it from the card. This ensures that any attempt at card tampering will be noticeable.
2. Tamper-Evident Features: Overlay materials often include tamper-evident patterns or elements that reveal any attempts at manipulation. This deters fraudulent activity and enhances the card’s security.

Applications of Overlay:

1. Identification Cards: In scenarios where the cardholder’s identity is critical, such as government-issued IDs, the high adhesion properties of Overlay add an extra layer of security.
2. Access Control Cards: Overlay is an essential component of access control cards, as it prevents unauthorized entry through tampering with the card.
3. Financial Cards: Debit and credit cards rely on Overlay materials to protect sensitive information and guard against tampering, ensuring the safety of financial transactions.

In conclusion, Corefilm and Overlay materials play pivotal roles in the production of secure cards for various applications.

Corefilm provides the backbone with its opacity, impact resistance, and lamination properties, making it an ideal choice for a wide range of cards.

Overlay, on the other hand, enhances the security of laminated cards by offering high adhesion properties and tamper-evident features.

As the world continues to grapple with security challenges, these materials remain integral in the fight against card fraud and data breaches, ensuring the protection of cardholders and sensitive information.
