Card Film PVC Overlay Film in Card Production

In our daily lives, we frequently interact with various types of cards - bank cards, identity cards, and membership cards. These cards not only carry critical personal information but also endure regular handling. Ensuring their durability and security is paramount, and this is where PVC (Polyvinyl Chloride) overlay films play a vital role.

What is PVC Overlay Film?

PVC overlay film is a thin, plastic sheet used to cover the surface of cards. This film is applied to both sides of the card, providing a protective layer that guards against physical damage and wear and tear. The use of PVC, known for its strength, flexibility, and resilience, makes these films an ideal choice for card production.

Manufacturing Process

Card Printing: Initially, the card's core material (usually PVC) is printed with the necessary information and designs.

Overlay Application: PVC overlay films are then applied to the printed card surface using lamination techniques. This process involves heat and pressure to ensure a strong bond between the film and the card.

Die-Cutting: After lamination, the sheets are cut into individual cards.

Key Features and Benefits

Durability: PVC overlay films protect cards from scratches, bending, and breaking, thereby extending their lifespan.

Security: For sensitive cards like bank and identity cards, these films can incorporate security features such as holograms, microtext, or UV printing to prevent counterfeiting and tampering.

Aesthetic Appeal: The film provides a smooth, glossy finish, enhancing the card’s visual appeal and allowing for vibrant, clear printing.

Functional Versatility: PVC films can be engineered to be compatible with various card technologies, including magnetic strips, chips, and RFID antennas.

Environmental Considerations

While PVC films are effective, there is growing concern about their environmental impact, given PVC’s non-biodegradable nature. The industry is exploring more eco-friendly materials and recycling methods to address these concerns.

Conclusion

PVC overlay films are an integral component in the production of various types of cards, offering a balance of durability, security, and aesthetic quality. As technology evolves, we can anticipate advancements in both the functionality and environmental sustainability of these films, continuing to safeguard and enhance the cards we use every day.
