Wholesale Prelam Inlay for Card

125KHz Inlay/ 13.56MHz Inlay 
In today’s rapidly evolving card manufacturing industry, RFID prelam sheets have become an essential component for producing high-quality smart cards. These sheets serve as the core structure that integrates RFID inlays — the embedded chips and antennas — into durable PVC layers, allowing for efficient mass production of contactless cards.

Wallis-Leading Prelam Inlay Manufacturer

 For About Inlay

An inlay is the internal layer of a card body, located between overlays. Unlike an overlay (which protects the surface), the inlay ensures the structural integrity of the card and can also house smart card technology such as RFID chips and antennas.
In the smart card industry, there are two main types of inlays:
Core Sheet Inlays – Plain structural core for standard cards.
RFID Prelam Inlays – Core sheets pre-laminated with RFID chips and antennas.

Inlay in Card Manufacturing

PVC Core Sheet Inlays

General Description

A PVC core sheet is the main body of the card.
Usually sandwiched between two overlay films.
Designed for durability, stability, and easy lamination.
 

RFID Prelam Inlays

General Description

A prelaminated inlay integrates an antenna and chip inside PVC sheets before lamination.
Provides contactless communication for modern smart cards.
Designed for high durability and seamless embedding into final card production.
 

125 kHz RFID Inlays (Low Frequency – LF)

125 kHz inlays are low-frequency RFID solutions that are widely used in applications requiring short-range, reliable communication. They work well in environments with metal or liquid interference where higher frequencies may fail.
 

13.56 MHz RFID Inlays (High Frequency – HF)

13.56 MHz inlays are high-frequency RFID solutions, offering better data capacity and security features than LF inlays. This makes them the standard for payment and transit systems.

Understanding Inlay Sheet

 

An inlay sheet is a specially prepared intermediate material used in card manufacturing (such as ID cards, smart cards, banking cards, membership cards, or RFID cards). It usually acts as the core structure of the card, placed between overlay films during lamination.

 

The inlay sheet determines many of the card’s key functions and properties, including durability, flexibility, and in some cases, electronic performance if embedded with RFID components.

 

Types of Inlay Sheets

Plain PVC Inlay Sheets
Made from standard PVC plastic.
Serve as the card’s structural base without electronic function.
Commonly used in simple printed cards (loyalty cards, student cards, membership cards).

 

RFID / Contactless Inlay Sheets

Contain embedded copper antennas and microchips.
Enable contactless technology such as 125KHz, 13.56MHz, or UHF frequencies.
Used in access control cards, transportation cards, payment cards, and NFC-enabled products.

 

Prelaminated (Prelam) Inlay Sheets

Pre-prepared inlays with antennas and chips already laminated inside PVC or PETG sheets.
Provide higher strength and easier further processing (printing, punching).
Widely used in industrial card manufacturing.

 
 

Introduce of Plain PVC Inlay Sheets

 

Plain PVC Inlay Sheets are basic core layers used in card manufacturing. They are made from polyvinyl chloride (PVC) material without any electronic components such as chips or antennas. Their primary role is to act as the structural foundation of a card, providing strength, durability, and a smooth surface for further lamination, printing, or personalization.

These sheets are placed between overlay films during the lamination process, where heat and pressure combine the layers into a finished card.

 

Advantages of Plain PVC Inlay Sheets


Cost-Effective – A more affordable option compared to RFID or electronic inlays.
Versatile – Suitable for many types of cards, from IDs to promotional cards.
Durable – Resistant to bending, cracking, and daily wear.
Customizable – Can be produced in different sizes, thicknesses, and colors based on client needs.
Compatible with Printing – Works well with offset printing, screen printing, digital printing, and lamination.
 

 

What are RFID / Contactless Inlay Sheets?
 

RFID (Radio Frequency Identification) / Contactless Inlay Sheets are specially designed core sheets that contain embedded electronic components—such as antenna coils and microchips—which allow cards to perform wireless communication.

These inlay sheets are the functional heart of contactless smart cards, enabling them to store and transmit data without physical contact. They are widely used in access control, transportation, banking, and NFC applications.

 

125KHz (Low Frequency – LF)


Range: 2–10 cm (short range).
Data Speed: Slow, limited memory capacity.
Performance: Works well near metal, water, and challenging environments.
Security: Basic, not encrypted; more suitable for simple identification.
Cost: Generally lower compared to HF and UHF.

 

13.56MHz (High Frequency – HF / NFC)


Range: Up to 10 cm.
Data Speed: Faster than LF, supports more complex data storage.
Performance: Good balance of range, speed, and security.
Security: Supports encryption & authentication (e.g., MIFARE®, DESFire®).
Standards: ISO/IEC 14443, ISO/IEC 15693, NFC.

 

UHF (860–960MHz, Ultra-High Frequency)


Range: Up to 10 meters (long range).
Data Speed: Very high; can read hundreds of tags at once.
Performance: Best for bulk reading and tracking, but less stable near liquids/metal.
Security: Moderate; newer protocols improve security but not as strong as HF for financial use.
Standards: ISO/IEC 18000-6C (EPC Gen 2).

 

 

 

What are Prelaminated (Prelam) Inlay Sheets?
 

Prelaminated Inlay Sheets, also called Prelam Inlays, are pre-prepared card core sheets that already contain embedded antennas and microchips, laminated inside durable materials such as PVC, PET, or PETG.

They serve as the functional base for manufacturing RFID smart cards, making the production process more efficient, stable, and reliable. Instead of assembling chips and antennas separately, card manufacturers can directly use prelam inlays, then print, punch, and finish the cards with overlays.

 

Key Features of Prelam Inlay Sheets


Integrated Structure – Chip and antenna are pre-laminated inside the sheet.
High Durability – Resistant to heat, pressure, and bending during lamination.
Stable Performance – Ensures proper chip-to-antenna bonding and alignment.
Easy Processing – Simplifies further card production steps like printing, punching, and personalization.
Customizable – Available in different sizes, frequencies (125KHz, 13.56MHz, UHF), and multi-chip designs.
