Magnetic strip films are integral to the world of smart cards, ID badges, gift cards, and banking cards. These strips store data magnetically and interact with card readers to facilitate various operations like access control, financial transactions, and loyalty programs.
With the rising demand for secure, durable, and cost-effective cards, materials like PVC (Polyvinyl Chloride), PC (Polycarbonate), and PET (Polyethylene Terephthalate) have become the industry's go-to options.
Understanding the fundamental materials is crucial when evaluating card manufacturing options. Each material has its unique benefits and use cases.
PVC is the most commonly used plastic for making cards. It offers:
Excellent printability
Flexibility and durability
Compatibility with magnetic stripes and lamination
PVC is cost-effective, making it ideal for short-term or disposable cards like hotel key cards or temporary badges.
Polycarbonate is a high-performance plastic that's:
Heat-resistant
Scratch-proof
Ideal for high-security cards like ID cards, government-issued cards
PC supports laser engraving and high-definition printing, adding security and durability to sensitive card projects.
PET and its glycol-modified version PETG offer:
Eco-friendliness and recyclability
Superior resistance to chemicals and UV
Long-lasting performance in demanding environments
PET is commonly used in cards that need both visual appeal and long-term durability.
Magnetic strip films store data on iron-based particles aligned in a magnetic field. When a card is swiped through or inserted into a reader, the machine interprets these magnetic signals to authorize access or complete a transaction.
Three magnetic stripe standards exist:
Low Coercivity (LoCo): Easy to erase; used in hotel key cards
High Coercivity (HiCo): Difficult to erase; used in credit/debit cards
Super HiCo: For ultra-secure, long-term cards like passports
Magnetic strip films typically include:
Base Material (PVC, PC, PET): The structural layer
Adhesive Layer: Bonds magnetic stripe to the base
Magnetic Layer: Contains iron oxide or similar particles
Overlay: Protects the magnetic layer from scratches and wear
This multilayer configuration ensures the card remains functional and legible through thousands of swipes.
Durability: Resistant to bending, abrasion, and environmental stress.
Customizability: Suitable for embossing, laser engraving, and UV printing.
Versatility: Compatible with contactless and chip-based enhancements.
Cost-Efficiency: Especially in bulk production for PVC and PET cards.
Sustainability: PET is recyclable, making it ideal for eco-conscious projects.
Glossy / Matte Finishing
UV Spot Coating
Hot Foil Stamping
Transparent / Frosted Layers
Holographic Elements
QR & Barcode Integration
Chip Embedding
Each finishing option enhances usability, aesthetics, or security depending on the card's purpose.
Choosing between PVC, PC, and PET for magnetic strip card production depends on your project's needs-whether you prioritize cost, durability, security, or sustainability. Each material offers distinct advantages, and understanding their properties will help you make the best decision for your business or institution.
Stay ahead by embracing the latest innovations in magnetic strip film technology while committing to eco-conscious, high-performance materials.
Polycarbonate (PC) offers the highest durability and is ideal for long-term, secure applications like ID cards.
Yes, hybrid cards can include magnetic stripes, chips, and even QR codes.
