Product Description

Introduction to PVC PC Core Sheet Middle Sheets

 

In the evolving world of card manufacturing, the PVC PC core sheet middle sheet plays an irreplaceable role in determining the overall quality, durability, and aesthetics of printed cards. Whether it's for banking, ID, membership, or RFID/NFC cards, the middle layer serves as the backbone of the card structure.

 

As customization trends and technological advancements rise, manufacturers are turning to custom color PVC PC core sheets for improved visual identity and performance. 

 

 

 

 

 

Why Middle Sheets Matter in Card Manufacturing

 

 

The Structural Role of Core Sheets

 

The middle sheet, often referred to as the core layer, is the foundational layer sandwiched between overlay and printed sheets. It provides rigidity, resilience, and dimensional stability to the card. Without a robust core, cards can warp, crack, or delaminate over time.

 

Impact on Print Quality and Lamination

 

Core sheets impact how well top layers bond during lamination, directly influencing print clarity and alignment. A high-quality PVC PC core ensures smooth bonding, reduces air bubbles, and supports high-definition graphics-making it essential for cards with security features or holograms.

 

 

Benefits of Custom Color PVC PC Core Sheets

 

Enhanced Visual Appeal

 

Custom color options like black, gold, transparent, red, or even metallic shades offer an elevated, premium feel to cards. This is especially effective for VIP or premium membership cards, where appearance matters as much as function.

 

Brand Differentiation

 

With intense market competition, businesses seek unique branding. Custom-colored cores act as a subtle brand identifier, setting cards apart from generic white-core alternatives.

 

Increased Security Features

 

Certain core colors make it more difficult to replicate cards, adding a layer of anti-counterfeiting. Combined with printed UV patterns or embedded chips, custom color cores increase card security.

 

 

 

 

 

Materials: PVC vs. PC - A Comparative Look

 

Durability and Flexibility

 

Feature	PVC (Polyvinyl Chloride)	PC (Polycarbonate)
Flexibility	Moderate	High
Impact Resistance	Good	Excellent
Temperature Tolerance	-10°C to 60°C	-40°C to 120°C
Lamination Performance	Excellent	Excellent

PVC is cost-effective and easy to process, making it a common choice. PC, on the other hand, is more resilient and suited for advanced applications like multi-layer smart cards.

 

Environmental Resistance

 

PC sheets are more resistant to UV exposure, moisture, and chemicals, which is why they're preferred for outdoor-use cards or those in harsh environments. PVC is suitable for most indoor or controlled-use scenarios.
 

 

Applications Across Industries

 

Banking and Financial Cards

 

PVC PC middle sheets provide a strong base for:

• Debit and credit cards

• EMV chip cards

• Contactless payment cards

 

 

ID and Access Control Cards

 

Used in:

• Employee ID badges

• Government IDs

• RFID/NFC-enabled door access cards

 

 

Membership and Loyalty Cards

 

Retailers, hotels, and clubs use vibrant colored core sheets to create:

• VIP loyalty cards

• Gift cards

• Subscription cards

 

 

Bonding with Overlay Films

 

Custom PVC PC cores work well with:

• Glossy or matte overlay films

• Magnetic stripe layers

• Scratch-resistant coatings

Proper bonding ensures card longevity and performance during repeated swipes or taps.
