Decoding the Dual-Side Treatment, Anti-Static Properties, and Optical Density for Advanced Smart Card Manufacturing
Product Overview
In the high-stakes world of smart cards, ID badges, and precision printing, a single speck of dust or a slightly unreadable magnetic stripe can render a product useless. This is why standard opaque films are not enough. Lumirror E22 White PET Film is the ultimate engineered substrate. As a dual-side pretreated, pigment-filled white film, it is built to deliver flawless ink adhesion, absolute opacity, and critical anti-static performance. In this technical breakdown, we examine why Lumirror E22 has become the gold standard for magnetic memory cards, IC cards, and high-end print receivers.
The Core Specs: Superior Treatment and Protection
What elevates Lumirror E22 above standard white films? The data sheet reveals a masterclass in functional surface engineering:
- Dual-Side Pretreatment for Adhesion: Both sides of the film are specially coated to guarantee excellent adhesion for magnetic stripes, printing inks, and protective laminates. This prevents peeling and delamination over time.
- Critical Anti-Static Performance: With a surface resistivity of 10^10 Ω, the film effectively dissipates static electricity. This is absolutely vital for preventing dust attraction during automated card manufacturing and avoiding static shocks that can damage IC chips.
- Exceptional Optical Density and Whiteness: With a whiteness index of 90.9 and an optical density ranging from 1.59 (at 188μm) to 1.93 (at 250μm), it provides a perfectly opaque, brilliant white background that ensures high contrast for card printing and barcodes.
Key Applications Across Industries
The unique properties of Lumirror E22 White PET Film make it indispensable for:
- Smart Cards and Magnetic Stripe Cards: The foundational core layer for public telephone cards, train tickets, subway passes, and “pachinko” cards.
- IC and Chip Cards: Providing a stable, anti-static base for embedded microchips.
- Print Receivers: Serving as a high-quality base for thermal or inkjet printing where a premium white, opaque finish is required.
Sourcing a Reliable Alternative
While Lumirror E22 White PET Film is a top-tier product, global buyers often seek a Lumirror E22 Alternative to manage costs and secure supply. A successful replacement requires a factory that can precisely replicate the dual-side treatment (to avoid ink peel-off) and the anti-static surface resistivity to protect sensitive electronic components.
