One Side Coated FBB Board
Surface Properties
Blister White Card
Glossy or matte plastic surface (Ra ≤ 1.5 µm) with excellent barrier properties (water vapor transmission rate: ≤ 5 g/m²/24h).
Heat-activated adhesiveness (melting point: 105–120°C for PE) enables blister packaging sealing.
Regular White Card
Porous, ink-absorbent surface (Ra 3–8 µm) optimized for offset or digital printing (ink holdout: 85–95%).
No heat-sealing capability; relies on glue for bonding.
3. Functional Performance
| Property | Blister White Card | Regular White Card |
|---|---|---|
| Thermoformability | High (forms 3D blisters at 120–150°C) | None (rigid, non-moldable) |
| Tensile Strength | 80–120 N/m (biaxial due to plastic layer) | 50–70 N/m (uniaxial, paper-dominant) |
| Moisture Resistance | IPX4 (resists splashes) | IPX0 (absorbs moisture >15% RH) |
| Seal Strength | 6–10 N/15mm (heat-sealed blisters) | 2–4 N/15mm (glue-only bonds) |
4. Applications
Blister White Card
Medical blister packaging (regulatory compliance: FDA, EU 10/2011).
Electronics (ESD-protective blisters).
Premium food packaging (microwave-safe PE laminates).
Regular White Card
Stationery (business cards, greeting cards).
Folding cartons (cosmetics, retail).
Print media (posters, brochures).
5. Sustainability
Blister White Card
Challenging to recycle (plastic-paper composite); requires specialized separation processes.
Emerging eco-alternatives: PLA laminates (compostable under industrial conditions).
Regular White Card
Highly recyclable (85–90% recovery rate).
FSC-certified options available for sustainable sourcing.
6. Innovation: Next-Gen Blister White Card
Nanotechnology Integration: Graphene oxide coatings for enhanced barrier (O₂ transmission: ≤ 0.5 cm³/m²/24h).
Smart Packaging: Thermochromic laminates that indicate tampering (color change at 37°C).
Adhesive-Free Sealing: Laser-weldable PET layers (seal strength +30% vs. traditional PE).
Visual Comparison (Analogy)
Blister White Card: A "hybrid armor" – paper rigidity + plastic versatility (like a waterproof book cover).
Regular White Card: A "printer's canvas" – optimized for ink adhesion and texture (like premium watercolor paper).
Technical Specifications (Example)
| Parameter | Blister White Card (Typical) | Regular White Card (Typical) |
|---|---|---|
| Basis Weight | 350 gsm (250 gsm paper + 100 µm PE) | 300 gsm (coated paper) |
| Thickness | 0.45 mm (with laminate) | 0.35 mm (unlaminated) |
| Gloss (60°) | 85–90 (plastic side) | 60–70 (coated side) |
| Oxygen Barrier | ≤ 2 cm³/m²/24h (PE laminate) | ≥ 500 cm³/m²/24h (uncoated) |
Conclusion
Blister white card is a engineered composite designed for functional packaging (thermoforming, hermetic sealing), while regular white card is a print-centric paperboard focused on aesthetics and versatility. The key differentiator lies in plastic integration (blister) vs. coating-only design (regular), leading to divergent performance in moisture resistance, formability, and end-use applications. Innovations in blister cards are pushing boundaries with sustainable laminates and smart features, whereas regular white cards evolve through coating technologies (e.g., nanocoatings for enhanced print gamut).
For industrial applications requiring both rigidity and functional packaging (e.g., medical devices), blister white card offers irreplaceable advantages. For creative print projects, regular white card remains the cost-effective, recyclable choice.
Note: All technical data align with ISO 22000 (food contact), ASTM D638 (tensile strength), and TAPPI T452 (gloss measurement) standards. Custom formulations (e.g., anti-microbial coatings for blister cards) are available for specialized industries.
