Wallis PVC core sheet is a rigid card substrate developed for professional plastic card manufacturing, printed card bodies, PVC inlay production, and contactless RFID card structures. Used as a central structural layer, it supports card flatness, mechanical strength, controlled flexibility, printing performance, and stable heat lamination.
The material is intended for B2B card manufacturers producing ID cards, bank cards, SIM cards, access cards, hotel key cards, membership cards, gift cards, transport cards, and RFID smart cards. Thickness, sheet dimensions, color, Vicat grade, surface dyne, and surface roughness can be matched to the card construction and downstream equipment.
For project evaluation, buyers should specify the finished card type, total card thickness, printing process, overlay or inlay structure, lamination conditions, and required sheet format. Wallis can then prepare a suitable sample for printing, lamination, punching, and finished-card testing before bulk production.
The following values are based on the current product specification supplied for this page. Final requirements should be confirmed by product grade, approved sample, quotation, and batch documentation before mass production.

A PVC core sheet is the structural substrate positioned between the protective overlays of a laminated plastic card. Depending on the design, the core may be printed directly, used as a non-printed middle layer, or converted into a plain or electronic inlay that accommodates an antenna, chip module, or other functional component.
Unlike an overlay film, which primarily protects the card surface, the core sheet contributes most of the card body’s opacity, stiffness, flatness, and dimensional stability. Consistent material properties are therefore important for registration, lamination, punching, personalization, and automated card handling.
PVC Core Sheet Material
Card-Grade PVC Substrate
Card projects should not select PVC core material by thickness alone. The suitable grade also depends on thermal response, printing method, embedded electronics, embossing or personalization process, card life, and the complete lamination stack.
| Card Application | Typical Core Requirement | Selection Focus | Recommended Validation |
|---|---|---|---|
| Standard ID, Membership and Gift Cards | Printable or non-printed white PVC core with balanced rigidity and lamination response. | Thickness, whiteness, flatness, print adhesion, die-cutting, and finished-card flexibility. | Print, laminate, punch, and bend-test representative cards. |
| Bank and Financial Cards | Controlled card-grade PVC matched to the approved overlay, magnetic stripe, chip, and personalization process. | Batch uniformity, lamination window, embossing or module embedding, and long-term card handling. | Approve the complete card construction, not the core sheet in isolation. |
| RFID and Contactless Prelam Inlays | Core or base sheet compatible with antenna and chip placement plus graded lamination. | Vicat behavior, sheet flatness, chip protection, antenna position, and bond integrity. | RF performance, cross-section, peel, lamination, and punching tests. |
| SIM and Telecom Cards | Higher-temperature grade where required by the approved SIM card body process. | Thermal stability, punching accuracy, module cavity processing, and card-body strength. | Thermal cycle, punch, module assembly, and dimensional checks. |
General-purpose grades are suitable for ID cards, membership cards, hotel key cards, loyalty cards, and promotional cards when the selected sheet is compatible with the printer, overlay, laminator, and target card construction.
Financial card production requires a tightly controlled combination of core sheets, overlays, magnetic stripe materials, chip modules, printing, lamination, and personalization. Buyers should provide the full layer structure and approval criteria when requesting a bank-card grade.
Contactless card inlays place electronic components inside the card body. A suitable PVC base sheet must laminate without shifting the antenna or applying excessive thermal and mechanical stress to the chip area. Trial production should confirm both card mechanics and RF performance.
SIM card materials may require a different thermal grade and converting behavior from ordinary PVC cards. Sheet thickness, Vicat value, surface properties, punching layout, module cavity, and downstream assembly should be specified before sample preparation.

| Layer | Primary Function | Key Compatibility Check |
|---|---|---|
| Top Overlay | Protects printing and may carry a magnetic stripe, hologram, or specialty coating. | Bonding, surface finish, magnetic stripe position, and personalization requirements. |
| Printed PVC Core | Carries graphics, text, security artwork, logos, and variable design elements. | Ink system, surface dyne, roughness, color consistency, and registration. |
| Middle Core or RFID Inlay | Builds card thickness and may contain an antenna and chip. | Vicat grade, electronics protection, flatness, and layer thickness calculation. |
| Reverse Printed Core | Provides reverse-side design and additional structural thickness. | Print-to-print alignment, color, and lamination balance. |
| Bottom Overlay | Seals and protects the reverse surface. | Bond strength, surface texture, and finished-card flatness. |
Stable sheet geometry helps maintain the intended card stack and supports consistent feeding, printing, lamination, punching, and finished-card thickness. For high-volume production, buyers should agree on tolerances and sampling methods in the approved specification.
Surface dyne influences how printing inks wet the PVC surface, while roughness affects transfer and contact. The listed dyne value provides a selection reference, but the final ink, curing method, press settings, storage history, and surface treatment should be verified on production equipment.
Vicat softening behavior influences how the sheet responds during heat and pressure lamination. Different card structures may require different grades, particularly when antennas, chips, magnetic stripes, SIM modules, or specialty overlays are involved.
Balanced strength and flexibility help reduce cracking, excessive burrs, deformation, and inconsistent card edges. Tool condition, cutting direction, sheet conditioning, and actual production speed also affect converting performance.
Printed PVC Card Applications
Smart Card and Inlay Applications
PVC core sheets can be specified for offset printing, silk-screen printing, UV printing, or use as a non-printed middle layer. Compatibility depends on the exact sheet surface and ink system. Buyers should provide the printing process and conduct adhesion, color, curing, and over-lamination tests.
The core sheet may be combined with PVC printing sheets, uncoated overlays, coated overlays, magnetic stripe overlays, or prelam inlays. Temperature, pressure, dwell time, cooling, stack symmetry, and release materials should be optimized for the complete construction.
For contactless cards, the material should be evaluated with the actual antenna geometry, chip position, cavity design, prelam thickness, and card layout. RF reading distance, resonance, chip survival, lamination flatness, and punching registration should be confirmed before volume production.
Card punching, module cavity milling, hot-melt embedding, embossing, and other finishing operations should be tested on the approved laminated card. Core-sheet results alone cannot predict every finished-card process.
A clear acceptance plan reduces disputes and repeat testing. The exact limits should be agreed in the purchase specification because they may vary by grade, thickness, sheet format, printing method, and card program.
| Inspection Area | Recommended Check | Buyer Decision |
|---|---|---|
| Dimensions | Thickness, sheet length and width, squareness, edge quality, and stack alignment. | Confirm tolerances and measuring method on the approved specification. |
| Surface | Color, contamination, scratches, pinholes, roughness, dyne level, and print-side identification. | Approve visual limits and sample reference before mass production. |
| Mechanical Properties | Density, tensile strength, rigidity, flexibility, punching behavior, and finished-card bend performance. | Use agreed test methods and conditioned samples. |
| Thermal and Lamination Response | Vicat grade, shrinkage, warpage, bubbles, delamination, cooling flatness, and layer registration. | Validate with the complete production stack and actual laminator. |
| Printing and Personalization | Ink adhesion, color reproduction, curing, overlay bond, embossing, magnetic stripe, chip, and personalization. | Approve a finished-card golden sample. |
| Packaging and Traceability | Quantity, labels, lot number, moisture protection, pallet condition, and shipment documentation. | Define label format and required documents in the purchase order. |

The physical specification on this page lists 0.10–0.50mm. The suitable thickness depends on the complete card construction and finished-card target. Other requirements should be submitted for technical and production confirmation.
The core sheet forms the structural body of the card and may carry printing or electronic components. An overlay is usually a thinner outer layer that protects printing and may include coatings, magnetic stripes, holograms, or other surface functions.
Yes. A suitable PVC grade can be used as the base or structural layer of contactless prelam inlays. The material must be validated with the actual antenna, chip, lamination cycle, inlay thickness, punching layout, and RF performance requirements.
The supplied specification lists a 90 ± 2°C Vicat grade for SIM card applications. Final suitability must be confirmed against the SIM card body structure, punching process, module cavity, assembly conditions, and customer test requirements.
PVC card sheets can be prepared for offset or silk-screen printing, but the exact grade must match the intended process. Buyers should test ink wetting, adhesion, curing, color, lamination, and finished-card performance before bulk production.
Surface dyne affects ink wetting and adhesion, while roughness influences printing contact, sheet feeding, and lamination. Both should be considered together with ink chemistry, press conditions, storage, and the selected overlay.
Custom requirements can be reviewed for thickness, dimensions, color, surface dyne, roughness, cutting, labeling, and packaging. Feasibility, MOQ, lead time, and tolerances depend on the requested specification.
Test the sheet through the complete workflow: printing, curing, lamination, cooling, punching, personalization, chip or antenna processing, and finished-card testing. A golden sample and written specification should be approved before the first bulk order.
Yes, provided the PVC core, magnetic stripe overlay, printing, lamination, and finished-card thickness are compatible. Stripe position, coercivity, bond strength, encoding, and personalization should be verified on finished cards.
Packaging commonly uses protective bags or film, cartons or rigid boards, pallets, edge protection, strapping, labels, and moisture protection according to sheet format and shipment method. The final packing plan should be confirmed in the quotation.
Sample availability can be discussed after the card application, thickness, size, color, surface requirement, and testing plan are provided. Sample approval is recommended before customized or high-volume production.
