Structure & Materials
Paper Layer:
White Surface: Single-sided coating (kaolin/calcium carbonate) for high-quality printing (gloss/matte finishes).
Blister Layer:
Materials: PVC (standard), PET (food-safe, recyclable), PS (rigid), or PLA (biodegradable).
Process: Vacuum thermoforming or adhesive lamination to create cavities (e.g., trays, inserts).
Key Properties
| Property | Description |
|---|---|
| Single-Side Printability | High-opacity white surface for CMYK/spot color printing (logos, product info). |
| Cost-Effective Rigidity | Thinner core than double-sided variants (180–250g) with comparable stiffness. |
| Moisture Barrier | Plastic layer prevents moisture penetration (PET: ideal for food contact). |
| Formability | Thermoplastic layer allows deep drawing (e.g., 50mm cavity depth). |
| Sustainability | Recyclable paper + optional biodegradable plastics (certifications: FSC, OK Compost). |
Applications
Food Packaging: Bakery trays (FDA-compliant PET), fruit clamshells, coffee capsule liners.
Electronics: Single-sided branded trays (e.g., earbud packaging with printed logos).
Retail Displays: Low-cost shelf-ready inserts (e.g., toy packaging with one printed side).
Industrial Use: Parts trays (anti-static coatings for electronics).
Manufacturing Process
Paperboard Production:
Single-sided coating → calendering → slitting (flatness ≤3mm/m).
Blister Molding:
Tooling: Custom molds (tolerance ±0.15mm for cost-effective mass production).
Thermoforming:
Heating: PVC (130–150°C), PET (170–210°C), PLA (140–160°C).
Vacuum/pressure forming (60–90 seconds) → cooling (chilled molds for precision).
Post-Processing:
Die-cutting → edge finishing (beveled edges for safety) → printing (flexo/gravure).
QC: Thickness (±5%), print density (ISO 12647), seal strength (for lidding applications).
Selection & Usage Guidelines
Critical Specifications:
Basis weight: 200–300g/㎡ (balance between formability and stackability).
Coating weight: 15–25g/㎡ (white side) for ink adhesion (≥80% gloss).
Tensile strength: ≥30N/15mm (machine direction).
Certifications:
Paper: FSC (sustainable forestry), PEFC.
Plastic: FDA (21 CFR 177.1630 for PET), EU 10/2011 (food contact).
Design Considerations:
Cavity Depth: Max 70mm (depends on paper thickness; 250g paper → 50mm depth).
Draft Angle: 2–5° for easy 脱模 (reduces material stress).
Storage:
Temperature: 15–25°C, humidity: 40–60% (prevents coating delamination).
Common Issues & Solutions
| Issue | Cause | Solution |
|---|---|---|
| Uneven Coating | Inconsistent paper sizing | Pre-inspect coating uniformity (ISO 536). |
| Blister Warpage | Asymmetric cooling (single-side heating) | Add baffles to molds for uniform cooling. |
| Print Smudging | Low surface energy (unprimed paper) | Apply corona treatment (38–42 dynes/cm). |
| Edge Cracking | Excessive die-cut pressure | Use laser die-cutting (0.1mm precision). |
Industry Standards & Trends (2025)
Standards:
ISO 19749 (blister packaging for medical devices).
ASTM D3359 (tape test for print adhesion).
Innovations:
Hybrid Materials: Paper-PLA composites (100% home-compostable by 2026, per EU EPR targets).
Digital Blistering: On-demand molds via 3D printing (reduces tooling costs by 40%).
Market Drivers:
Food safety: 90% of global food blisters use FDA-compliant PET (Grand View Research, 2024).
E-commerce: Lightweight designs (200g paper + 0.2mm PET) reduce shipping costs by 15%.
Real-World Example: Food Tray
Specs: 220g FSC-certified white board + 0.25mm PLA blister.
Application: Single-sided printed berry tray (logo on white side, uncoated gray side for moisture resistance).
Certifications: OK Compost (TÜV Austria), FDA 21 CFR 177.2420 (PLA).
Performance: Stackable (20kg load), 100% compostable, print CIE Lab* ΔE ≤1.5.
Conclusion
Blister single-sided white board paper optimizes cost and functionality for applications requiring one-sided branding or protection. Key advantages include targeted printability, lightweight rigidity, and sustainability options (e.g., PLA composites). To ensure success:
Match paper weight to application (200g for food, 300g for industrial).
Specify certifications (FSC, FDA) for compliance.
Partner with suppliers using digital mold technology (reduces lead time to 7 days).
Industry Forecast
CAGR of 6.8% (Grand View Research), driven by e-commerce and sustainable packaging mandates.
40% of blister packaging to adopt bio-based plastics (EU SUPD Phase 2 compliance).
This guide reflects 2025 global manufacturing practices, including advanced thermoforming (e.g., infrared heating for PLA) and circular economy initiatives (e.g., paper-plastic recycling via chemical delamination).
Glossary:
