1. Printing Issues
Problems:
● Poor ink absorption, leading to slow drying and smudging.
● Uneven color distribution and blurry images.
● Poor ink adhesion, especially with UV printing.
Solutions:
✅ Use fast-drying inks or UV-curable inks and adjust printing pressure accordingly.
✅ Opt for low-viscosity inks to improve print uniformity.
✅ Perform surface treatments such as corona treatment or priming to enhance ink adhesion.
2. Die-Cutting and Waste Removal Issues
Problems:
● Cast coated paper is brittle, making it prone to cracking or chipping during die-cutting.
● Difficult waste removal, reducing production efficiency.
● Uneven cutting edges, leading to labels peeling off or rough edges.
Solutions:
✅ Use sharp die-cutting blades to improve precision and minimize edge cracking.
✅ Adjust die-cutting pressure to prevent paper breakage.
✅ Modify the waste removal process by widening waste edges or optimizing the cutting layout.
3. Adhesion Problems
Problems:
● The glossy surface makes it difficult for adhesives to bond properly.
● Labels may curl or lose adhesion over time.
● Adhesive performance weakens in cold or humid environments.
Solutions:
✅ Choose high-tack adhesives specifically designed for cast coated paper.
✅ Ensure labels are fully dry before storage to prevent adhesive degradation.
✅ Use suitable release liners (e.g., glassine or PET) to prevent curling.
4. Water and Abrasion Resistance
Problems:
● Exposure to moisture can cause bubbling or coating detachment.
● Labels are prone to scratching or wear over time.
Solutions:
✅ Select waterproof cast coated paper or apply an additional water-resistant coating.
✅ Use scratch-resistant coatings or lamination to enhance durability.
✅ Apply UV varnish for extra abrasion resistance.
5. Warping Due to Temperature and Humidity Changes
Problems:
● Paper deforms when exposed to moisture, affecting label application.
● High temperatures can soften the coating, reducing adhesion quality.
Solutions:
✅ Store in a controlled environment (recommended: 20-25°C, 40-60% humidity).
✅ Avoid prolonged exposure to heat or humidity during transport.
✅ Use thicker or composite materials for better stability.
6. Environmental and Regulatory Compliance
Problems:
● Some coatings may not comply with environmental regulations, affecting exports.
● Cast coated paper is less recyclable, increasing sustainability concerns.
Solutions:
✅ Choose materials that meet ROHS, REACH, or other regulatory requirements.
✅ Use eco-friendly water-based coatings to minimize chemical impact.
✅ Opt for recyclable or biodegradable label materials to align with sustainability goals.
Conclusion
Cast coated paper is widely used in the labeling industry but presents challenges such as printability, die-cutting, adhesion, and durability. By optimizing ink selection, adjusting cutting processes, improving adhesives, and enhancing resistance properties, its performance can be significantly improved.
