Comprehensive Guide to Holographic PVC Rainbow Film Overlays for High-Quality Card Manufacturing

In the ever-evolving world of card production, the application of holographic PVC rainbow film overlays has become a cutting-edge solution that enhances both security and visual appeal. At Wallis Technology, we specialize in delivering a wide array of overlay films tailored for ID cards, membership cards, banking cards, smart cards, and other plastic-based applications. Below, we present a detailed exploration of the different types, uses, and advantages of holographic rainbow film overlays to help manufacturers and designers choose the right type for their specific card-making needs.

What is Holographic PVC Rainbow Film Overlay?

Holographic PVC rainbow film overlay is a specialized plastic film designed to be laminated over the surface of printed PVC cards. It introduces a multi-color, iridescent holographic effect that not only enhances the aesthetic appeal of the card but also adds a layer of anti-counterfeit protection. These films are commonly used in the production of high-security cards, including national ID cards, driver's licenses, access control cards, and financial cards.

Types of Holographic PVC Rainbow Film Overlays

Choosing the right holographic overlay film is critical for ensuring optimal compatibility with card substrates and meeting the desired security or decorative features. Below are the most widely used categories:

1. Transparent Holographic Overlay Film

This film features a transparent base embedded with holographic patterns, allowing the underlying card design to remain visible. Ideal for ID cards and event passes, it ensures that printed data is not obstructed while still benefiting from holographic security.

• Common Patterns: Stars, globe, waves, custom logo

• Thickness Range: 25μm to 50μm

• Application Method: Lamination (with heat and pressure)

2. PVC Rainbow Overlay Film with Iridescent Finish

PVC rainbow overlay films reflect multiple colors when viewed from different angles, producing a stunning iridescent sheen. These films are widely adopted in VIP cards, promotional cards, and artistic applications where appearance matters.

• Material Composition: PVC with PET hybrid layers

• Available Colors: Silver rainbow, golden rainbow, laser spectrum

• Finish: Glossy or matte

3. Custom Logo Holographic Overlay

For brands or institutions looking to strengthen their identity and anti-counterfeiting measures, custom logo holographic overlays offer personalized hologram images that can include text, logos, symbols, or even dynamic designs.

• Custom Order Requirement: Die origination or master hologram creation

• MOQ: 50,000 sheets or upon negotiation

• Compatibility: PVC, PETG, ABS base cards

4. Overlay Film with Security Microtext or Guilloche Patterns

These overlays come embedded with security features like guilloche lines, microtexts, and fine-line structures that are difficult to replicate. Often used in government-issued ID cards, access control badges, and transport cards.

• Security Level: High

• Print Type: Transparent with embedded graphics

• Anti-fraud Rating: Advanced

5. Hot Stamping Holographic Overlay Film

Unlike traditional laminated overlays, hot stamping films are transferred onto the card surface using heat and pressure without adhesive layers, providing a thin, seamless finish.

• Application Tools: Hot stamping machines or hologram applicators

• Durability: High adhesion, scratch-resistant

• Features: Cost-effective for large production runs

Key Features and Benefits of Holographic PVC Rainbow Films

Enhanced Card Security

The optical diffraction effects and embedded holographic patterns make it nearly impossible to duplicate or forge cards. The films provide a strong visual deterrent against tampering and fraud.

Improved Aesthetic Value

Holographic overlays add a premium, futuristic finish that elevates the visual appeal of even the simplest card designs. This helps increase the perceived value of the product.

Durability and Protection

Overlay films offer a protective shield against wear, scratches, moisture, and fading, thereby significantly extending the lifespan of printed cards.

Heat and Lamination Compatibility

Most of these films are designed for seamless lamination onto card surfaces using standard card lamination machines, with adjustable pressure and temperature controls.

Customizability

Brands can custom-design their holographic patterns, ensuring unique and recognizable visual elements that help with authentication and brand consistency.

Applications of Holographic PVC Rainbow Film Overlays

1. National ID and Government Cards

These overlays are vital in preventing ID fraud in citizenship cards, driver’s licenses, and social security cards. Government agencies often rely on high-security custom holographic films to maintain the integrity of issued IDs.

2. Financial and Bank Cards

Banks use holographic overlays to add a layer of security to debit or credit cards. The shimmering finish also serves as a visual branding element that enhances customer trust.

3. Employee and Access Control Cards

By embedding unique security patterns in overlays, companies can protect their premises through verifiable access cards that are difficult to replicate.

4. Loyalty and Membership Cards

Retailers, hotels, and entertainment venues use these films to produce eye-catching loyalty cards that create a lasting brand impression and drive customer engagement.

5. Student and Campus Cards

Universities and schools benefit from the custom security overlays for issuing multifunctional student cards that serve as IDs, payment systems, and library access tools.
