El rendimiento del PVC, con un plan de salida
La misma prensa, las mismas cerraduras, la misma durabilidad — pero diseñado para descomponerse en condiciones de vertedero, con informes de prueba ASTM independientes que lo demuestran.
El PVC degradable incorpora aditivos que permiten que el material se degrade tras su disposición en condiciones de vertedero biológicamente activo, verificado en las pruebas ASTM D3826 y D5208. Para su operación, nada cambia: el mismo espesor, el mismo comportamiento de impresión, las mismas opciones de chip y el mismo manejo en recepción.

Informes de prueba independientes ASTM D3826 / D5208 disponibles para su expediente de compras.
Ningún cambio de proceso
Reemplazo directo del PVC estándar — las mismas cerraduras, codificadores y hábitos.
Sobreprecio moderado
Un pequeño incremento sobre el PVC estándar, muy por debajo de las tarjetas de madera o especiales.
Degradable PVC — technical data
- Card body
- Card-grade PVC compounded with an organic degradation accelerant — no change to sheet chemistry a guest or encoder could detect
- Look and feel
- Visually and mechanically identical to standard PVC: same whiteness, stiffness and print response
- Finished thickness
- 760 μm / 30 mil (CR80), laminated from the same core-and-overlay build as standard PVC
- Heat stability
- Vicat softening 80–86 °C — unchanged from standard PVC. Compostable PLA/PHA sheet softens at 50–60 °C by comparison
- Mechanical strength
- Tensile strength ≥ 40 MPa (MD); surface matte Rz 4–10 μm; wetting tension ≥ 38 dyn/cm
- Degradation
- Accelerated anaerobic biodegradation demonstrated under ASTM D5511 (simulated landfill conditions)
- Shelf behaviour
- Fully stable in storage, encoding and daily guest use — degradation only activates in a microbe-rich landfill environment
- Chip compatibility
- All 125 kHz and 13.56 MHz chips, magstripe and hybrid builds — identical to standard PVC
Inside a degradable PVC card
The build is deliberately identical to a standard PVC card — same five-layer laminate, same inlay bonding, same encoders. The only change is inside the resin: an organic additive that lets landfill microbes colonise and break down the polymer chain after disposal.
≈ 760 μm finished — indistinguishable from standard PVC in use
- Clear overlay · 40–100 μm Degradable-grade film; protects print exactly like standard overlay
- Printed core · 100–400 μm Additive-compounded PVC core, front graphics
- RFID inlay Etched antenna + chip, adhesive-film bonded
- Printed core · 100–400 μm Back graphics and guest instructions
- Clear overlay · 40–100 μm Sealed back face
When degradable PVC is the right call
- You want an eco upgrade with zero workflow change: same encoders, same printers, same guest experience, same price ballpark.
- Heat stability matters: it keeps PVC’s 80–86 °C Vicat point, where compostable PLA sheet (50–60 °C) risks warping in hot mail and parked cars.
- Your brand reports ESG: an ASTM D5511 test trail gives sustainability teams a citable line item.
Degradable PVC questions
Does degradable PVC look or feel different from standard PVC?
No. The degradation accelerant changes nothing a guest, encoder or printer can detect — whiteness, stiffness, print response and heat stability all match standard card PVC. That is the point: an eco swap that requires no retraining and no new hardware.
How fast does it actually degrade?
Under ASTM D5511 test conditions (anaerobic, microbe-rich — simulating an active landfill) the material shows substantially accelerated biodegradation versus standard PVC, which persists indefinitely. Real-world rate depends on landfill activity, so we cite the test method rather than promising a fixed number of years.
Why not just use compostable PLA or PHA cards?
Bio-based PLA/PHA card sheet composts cleanly to CO₂ and water, but it softens at 50–60 °C — a card mailed in summer or left on a dashboard can warp before first use — and it costs more. Degradable PVC keeps PVC’s 80–86 °C stability and price while fixing the end-of-life story.
Will cards start breaking down in storage or in guest use?
No. Degradation needs sustained contact with the microbe-rich, oxygen-poor environment of a landfill. In a drawer, wallet or encoder the card behaves exactly like standard PVC for years.
