0.15–0.3mm White PVC, PETG and PC Core Sheet for Card Manufacturing
Wallis 0.15mm and 0.3mm white PVC, PETG and PC core sheets are engineered for professional plastic card manufacturing. Depending on the selected material grade and card construction, these sheets can serve as printable layers, structural middle layers or supporting layers in ID cards, bank cards, SIM cards, access cards, membership cards, gift cards and RFID smart cards.
For B2B card manufacturers, the correct white core sheet must match the printing system, lamination temperature, overlay material, chip or antenna structure and target finished-card thickness. Wallis supports custom thickness, sheet size, whiteness, matte or glossy surface, cutting and sample testing before volume production.

How to Select PVC, PETG or PC White Core Sheet
PVC, PETG and polycarbonate are not interchangeable grades. Each material has a different processing window, rigidity, heat response and target application. The correct selection should be based on the complete card structure rather than price or thickness alone.
| Material | Typical Strengths | Common B2B Applications | Validation Focus |
| PVC Core Sheet | Cost-efficient processing, broad printing compatibility and established card-production workflows | Membership cards, gift cards, hotel cards, standard ID cards and general smart cards | Vicat grade, surface dyne, roughness, thickness stability and overlay bonding |
| PETG Core Sheet | Good toughness, flexibility and lamination compatibility for PETG or composite card structures | Premium cards, selected ID cards, durable smart cards and PVC/PETG composite structures | Lamination temperature, shrinkage, surface tension, peel strength and ink system |
| PC Core Sheet | High heat resistance, strong mechanical durability and compatibility with security-card structures | Government IDs, driver licenses, secure access cards and laser-personalized cards | Laserable grade, layer compatibility, lamination program and finished-card testing |
0.15mm vs 0.30mm White Core Sheet
The sheet thickness must be calculated as part of the full card stack. A finished ISO-format plastic card normally combines multiple printed, core, inlay and overlay layers. Therefore, 0.15mm or 0.30mm describes an individual layer, not necessarily the final card thickness.
| Thickness | Typical Role | Selection Considerations |
| 0.15mm | Thin printed layer, supporting layer, split-core construction or multi-layer smart card structure | Useful when several functional layers must fit within the target card thickness; verify flatness and handling during printing |
| 0.30mm | Structural middle layer, thicker printed core or support around chip and antenna assemblies | Provides greater layer thickness but must be balanced with overlays, inlays and final punching requirements |
| Custom Thickness | Special card stack, dual-interface card, SIM card or proprietary card construction | Provide a layer diagram, target final thickness and lamination process when requesting a quotation |

Role of White Core Sheet in a Laminated Card Structure
In a laminated card, the white core sheet creates the opaque base behind graphics and personalization data while contributing to card flatness and rigidity. For RFID or NFC cards, one or more core layers may surround the antenna and chip inlay. The final construction can also include printed sheets, clear overlays, magnetic stripe layers, holographic security films and signature panels.
Printed Card Layer
A printing-grade white core sheet provides a bright background for text, photographs, barcodes and brand graphics. Surface treatment must be selected for the intended ink and printing equipment.
Structural Middle Layer
The middle layer helps control rigidity, flatness and total card thickness. Its material should be compatible with adjacent layers to reduce warping, bubbles or delamination.
Smart Card and RFID Inlay Support
For contactless or dual-interface cards, the layer design must leave suitable space for the antenna, module and connection area. Sample lamination and electrical testing are recommended before mass production.
Printing and Surface Compatibility
A material described as “printable” is not automatically suitable for every printing technology. Offset and silk-screen card sheets generally rely on controlled surface tension and roughness, while inkjet and some digital systems may require a dedicated receptive coating. Buyers should identify the printer, ink brand, curing method and required lamination process before selecting the grade.
| Printing Process | Required Sheet Considerations | Recommended Pre-Production Test |
| Offset Printing | Controlled dyne level, suitable roughness, stable whiteness and ink compatibility | Ink adhesion, drying, color density and post-lamination bond |
| UV Printing | Surface compatible with UV ink and curing energy without excessive distortion | Cross-hatch adhesion, cure quality, bending and lamination test |
| Silk Screen Printing | Ink system matched to PVC, PETG or PC and controlled surface treatment | Adhesion, opacity, drying and resistance after lamination |
| Inkjet or Digital Printing | Dedicated coated grade may be required; ordinary uncoated core sheet should not be assumed compatible | Dot definition, ink absorption, rub resistance and coating-to-overlay bond |

Key Manufacturing and Quality-Control Requirements
Thickness consistency: supports predictable card-stack calculations and uniform lamination.
Flatness: improves sheet feeding, registration, stacking and die-cutting.
Whiteness and color consistency: helps maintain repeatable printed color across production lots.
Surface dyne and roughness: influence ink adhesion and print definition.
Vicat and thermal response: must match the selected lamination cycle and adjacent materials.
Lamination bond: should be evaluated with the actual overlay, ink and production equipment.
Finished-card performance: verify bending, punching, chip function, antenna reading and surface appearance.

Frequently Asked Questions
What is the difference between a card core sheet and an overlay film?
A core sheet forms the printed or structural body of the card. An overlay is normally a thinner protective outer layer placed above the printed layer. The exact function depends on the card design and material grade.
Is 0.15mm suitable for a complete plastic card?
Usually, 0.15mm is one layer within a multi-layer card rather than the complete finished card. The final construction may combine two or more core sheets, an RFID inlay and protective overlays.
When should I choose a 0.30mm core sheet?
A 0.30mm sheet may be selected when the card structure needs a thicker middle layer or additional support around a chip or antenna inlay. The final choice must be calculated with all other layers.
Which material is best for standard membership or gift cards?
PVC is commonly selected for cost-efficient, high-volume card production. Buyers should still confirm surface grade, printing method, lamination temperature and required card lifespan.
When is PETG core sheet a suitable option?
PETG can be considered for card structures requiring good toughness and PETG or composite lamination. Sample testing is necessary because PETG has a different thermal processing window from PVC and PC.
When should a buyer specify polycarbonate core sheet?
PC is commonly considered for higher-security and longer-life card structures, particularly when laser personalization or higher lamination temperatures are involved. The buyer should specify whether a laserable grade is required.
Can the same sheet be used for offset and inkjet printing?
Not automatically. Offset and silk-screen sheets may be uncoated, while inkjet printing often requires a dedicated receptive coating. Provide the printer and ink information before ordering.
Can Wallis customize sheet size and thickness?
Yes. Custom thicknesses and sheet formats can be discussed according to the card-layer drawing, printer format, laminator size and volume requirements.
Can these sheets be used for RFID and NFC cards?
Yes, suitable grades can be used around RFID or NFC inlays. The complete construction should be tested for lamination bonding, antenna performance, chip connection and finished-card flatness.
What information is needed for a quotation?
Please provide the material, thickness, sheet size, surface finish, whiteness or color, printing method, overlay material, quantity, packaging requirement and target card application.
Are samples recommended before bulk production?
Yes. Samples allow the buyer to test ink adhesion, color, lamination, die-cutting, chip or antenna function and the final card structure before approving volume production.
How should white card core sheets be stored?
Keep the material sealed in its original packaging, protected from moisture, dust, direct sunlight, heavy pressure and major temperature fluctuations. Store sheets flat unless the approved packaging specifies otherwise.
