The special materials for making PVC cards mainly include PVC sheet bases, PVC with adhesive films, and PVC transparent substrates for inkjet printing, etc. They are the core raw materials for manufacturing membership cards, IC cards, business cards, etc.
PVC substrate: As the main material for the cards, it usually has a thickness of 0.3mm. The surface has been specially treated to enhance the adhesion of ink, and it is suitable for inkjet or offset printing. It has good flatness and thermal stability, and is the basic material for card-making processes without laminating or layering.
PVC with adhesive film (also known as laminated film): A PVC film coated with hot-melt adhesive on the surface, with a thickness of generally 0.08mm. It is adhered to the PVC substrate by heating and pressure, serving to protect the printed layer, enhance glossiness and wear resistance. Its peel strength is ≥ 5N/cm, and the layering temperature range is 110℃ to 150℃. It is widely used in the production of ID cards, VIP cards, etc.
PVC inkjet-printed transparent substrate: A new type of card-making material that enables mirror-image inkjet printing, achieving photo-quality pattern effects. Suitable for personalized information printing. Combined with traditional printing techniques, it can significantly enhance card-making efficiency and reduce costs. PVC Business Card Special Materials: Used for making special types of business cards such as transparent cards, matte cards, and frosted cards, with a thickness of approximately 0.3 - 0.38mm. These cards have waterproof, oil-resistant, and resilient properties, and support post-processing techniques like gold stamping and UV coating. They are widely used in business communication scenarios.
These materials are all composed mainly of polyvinyl chloride resin. By adding plasticizers, stabilizers and other auxiliary materials, their properties are adjusted to ensure that the cards maintain bright colors, stable structure and are not prone to aging during long-term use.
