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.

What Is Metallized Paper? A Basic Review
Metallized paper is a composite material created by depositing an ultra-thin layer of aluminum onto the surface of paper via physical or chemical methods. It retains the flexibility and printability of paper, while also offering metallic gloss, barrier properties, and more.
Unlike aluminum foil paper, the aluminum layer in metallized paper is much thinner, usually between 0.01–0.03μm, making it more process-friendly and environmentally sustainable.
Common base papers include:
White board paper
Coated paper
Kraft paper
Dust-free paper
These substrates undergo pretreatment and are then metallized via vacuum deposition or transfer methods, making them ideal for premium packaging, food bags, wine boxes, gift boxes, and other applications.
Core Production Process of Metallized Paper
1. Substrate Pretreatment
Before metallizing, the paper surface is treated (e.g., gluing, glazing, or coating) to improve adhesion of the aluminum layer. This step significantly impacts the final product’s durability and print compatibility.
2. Vacuum Metallization
Currently the most mainstream and industrially efficient metallizing technique.
Working Principle:
Aluminum wire is placed in a high vacuum chamber and heated via resistance or electron beam, turning it into a vapor that condenses evenly on the paper’s surface.
Steps:
Heat aluminum wire to >1500°C until it vaporizes
Aluminum vapor condenses onto fast-moving paper rolls under vacuum via cathode radiation
The layer is cooled to form a film and rewound
Optional post-processing includes lamination, embossing, or varnishing
Equipment Involved:
Vacuum metallizer
Tension control system
Roll-to-roll transport system
3. Post-Processing
Depending on customer needs, the metallized paper can undergo various enhancements:
Embossing: Adds tactile and 3D effects
Matte Lamination: Reduces glare and adds a premium feel
Hot Stamping / Thermal Transfer: Enhances decorative appeal
Laminating: For multi-layer structures like food-grade heat-sealable bags
Key Differences Between Vacuum Metallization and Other Technologies

FAQ
Q1: What is the aluminum thickness in vacuum metallization?A: Typically 0.01–0.03 microns, hundreds of times thinner than aluminum foil, but still offers excellent reflectivity and barrier properties.
Q2: Is metallized paper prone to delamination?A: High-quality vacuum metallization ensures strong adhesion, especially when surface tension exceeds 38 dyn/cm.
Q3: Is it safe for food contact?A: Only if it has FDA or EU food contact certification. A PE or PET barrier film is recommended.
Q4: Can metallized paper be heat-sealed?A: Not directly. Lamination or composite layers are needed to form a heat-sealing layer.
Q5: How to evaluate coating quality?A: Through abrasion tests, peel tests, and optical density measurements to assess adhesion and uniformity.
Conclusion: Understanding the Process Is the First Step to Competitive Packaging
In today’s world of differentiated packaging, materials are not just protective shells—they are the first visual language of a brand. Vacuum metallized paper, with its balanced strengths of cost, gloss, eco-friendliness, and adaptability, is a preferred material for many international brands. If you are planning a packaging upgrade, mastering the metallization process will empower you to make smarter decisions.
