Product Description
RFID Prelam is a core fundamental component of radio frequency identification systems. Composed of PET substrate, smart chip and induction antenna through precision lamination, it is mainly divided into two mainstream types: dry adhesive-free and wet adhesive-backed. Supporting multiple frequency band specifications including UHF, HF and NFC, it serves as the essential base material for manufacturing various RFID tags and smart cards. Featuring lightweight, flexible and high compatibility, it supports fast contactless reading, multi-tag batch reading, stable data storage, strong anti-interference capability and excellent durability, and can be custom cut to fit diverse application scenarios. Our RFID Prelam feature exquisite craftsmanship, stable reading distance and low loss rate, which are compatible with secondary processing such as film coating, labeling and card mounting with high cost performance. Widely applied in retail apparel inventory management, logistics and warehousing traceability, access control identification, hotel key cards, medical asset management, product anti-counterfeiting traceability and campus smart card systems, they enable efficient intelligent identification, tracking and management of items. Helping industries reduce costs and improve efficiency, our RFID Prelam are premium core accessories for IoT intelligent identification scenarios.
The four core advantages of RFID Prelam:
1. Superior Yield & Stable Quality: Our RFID Prelam adopt ultra-flat PET substrate with precise antenna etching and solid chip bonding. With highly consistent batch parameters, they effectively avoid common card-making defects such as bubbles, position offset and layer cracking during hot pressing, lamination and die-cutting processes. The stable physical and electrical performance greatly improves the finished smart card yield rate and reduces defective rates for manufacturers.
2. Full-Frequency Compatibility & Wide Application: Covering HF, NFC and UHF full frequency bands, our RFID Prelam are fully compatible with the production of various smart cards, including access control cards, hotel key cards, campus cards, membership cards and anti-counterfeiting cards. Uniform inductance and stable read-write performance ensure zero signal difference of finished products, perfectly meeting diverse customized card-making requirements for different industry scenarios.
3. Excellent Process Adaptability & Cost Efficiency: Optimized for standard card-making procedures, the Prelam withstand high temperature and high pressure in coating, laminating, embedding and die-cutting processes with strong production tolerance. We support large-volume batch supply with stable delivery cycles and low processing loss. It helps card manufacturers simplify production procedures, improve overall processing efficiency and effectively control production costs to boost market competitiveness.

2. The printing of the RFID Prelam: There are two printing methods in our factory: screen printing and offset printing. If you need any of the printings support, we could provide you with the printing of the RFID Prelam.
3. Ultrasonic chip installing: We have a separate workshop to install the chip onto the RFID Prelam. If you are lack of means to load chips, we could help you install the chips on the RFID Prelam.
4. Card patchwork synthesis: Our factory could perform three-layer splicing on the card through temperature changing. If you need to splice the Rfid Prelam, we could provide you with the related services.
5. Card rush cutting: There are three machines in our rushing card workshop face different cutting situations. If you need to cut your cards into pieces or into special shapes, we could provide you with the cutting services.
6. Card code number processing: We could provide you with many kinds of card code number printing, such as Embossing number, signature panel, UV/Flat serial number, barcode, scratch-off, magnetic stripe, punching hole, UV coating, gold stamping and so on. If you are interested in it, you could ask us for free samples.
FAQS
Q1: What is your RFID prelam? What material is it made of?
A1: Our RFID prelam (pre-laminated sheet) is a semi-finished core material with an RFID Prelam already embedded between plastic layers. It is ready for card manufacturers to print, laminate and convert into finished RFID cards. Standard material is PVC, and we also offer PET, PETG or PC according to your requirements. The surface is flat, smooth and dust-free, which gives stable printing and lamination results.
Q2: Which frequencies and chips can you support?
A2: We support all main RFID frequencies and ICs: - LF 125 kHz: EM4100, EM4200, T5577, etc. - HF 13.56 MHz: NXP MIFARE Classic 1K/4K, Plus, DESFire EV1/EV2/EV3, Ultralight, NTAG213/215/216, ICODE SLIX, etc. - UHF 860–960 MHz: Impinj Monza series, NXP UCODE series, etc. Dual-frequency combinations are also available. Please tell us your chip model and application, and we will supply the correct prelam for your card.
Q3: What sheet sizes and layouts (cards per sheet) do you offer?
A3: We supply standard panel sizes and popular layouts such as 2x4, 2x5, 3x6, 3x7, 3x8, 4x5, 4x6, 4x7, 4x8, 4x10, 5x5, 6x7,6x8 cards per sheet, normally to fit the standard CR80 card size of 85.6 x 54 mm per ISO 7810. Custom sheet sizes and card layouts are available on request.
Q4: What thickness can you make, and how does it match a finished card?
A4: Common prelam core thicknesses are 0. 3mm, 0. 35mm, 0. 4mm, 0. 45mm, 0. 50mm,0.55mm and 0. 60mm, and customized thickness is available. We control the thickness tightly to help you reach the standard finished card thickness of 0.76 mm (ISO 7810 ID-1) after adding your printed overlay films and final lamination. Please tell us your target finished card thickness and layer structure, and we will recommend the correct core thickness.
Q5: What is your MOQ?
A5: Our MOQ is normally 【500 sheets / 1,000 sheets / 3,000 sheets per layout】, depending on the chip type, Prelam design and material. For first-time trial orders we can be more flexible, so please contact us with your target quantity for a confirmed quotation.
Q6: Do you provide samples? What is the sample cost and delivery time?
A6: Yes, samples are available. We can supply free samples with freight paid by the buyer, or paid samples including freight, depending on the quantity and destination. Samples normally take 【3–5 working days】 to prepare. Mass production lead time is about 【7–15 working days】 after sample approval and deposit confirmation.
Q7: Can we print on the prelam and use our normal card lamination process?
A7: Yes. Our prelam is designed for standard card production: reverse printing or overlay-film printing can be applied on top, followed by final lamination and punching. The RFID Prelam area is completely flat, so it will not cause deformation or bubbles. We will provide our recommended lamination temperature, pressure and time to protect the chip and antenna during final lamination.
Q8: Do your products meet international standards and certifications?
A8: Yes. Our prelam is produced to meet ISO 7810 (card size and physical characteristics) and works with ISO 14443 / ISO 15693 / ISO 18000 RFID protocols. Materials are RoHS and REACH compliant. If you need specific certification documents (e.g., test reports) for your market or end customer, we can provide them upon request.
Q9: What is your after-sales service like?
A9: We offer a comprehensive after-sales service, including a 5+ year warranty, 1:1 compensation for any issues, and regular follow-ups to ensure customer satisfaction.
Q10: What are your company's main markets?
A10: Our primary markets are Europe and America, where we have established a strong presence and a reputation for quality and reliability.
