With the rise of eco-consciousness and continuous upgrades in packaging design, metallized paper has rapidly become a popular choice in packaging for food, tobacco, alcohol, cosmetics, and more. Combining visual appeal, functional properties, and environmental friendliness, it is highly attractive to brand owners, packaging manufacturers, and procurement managers. Understanding the core production processes of metallized paper, especially the difference between vacuum metallization and other methods, helps in making cost-effective and competitive material decisions.

Use corona treatment or pre-coating layers to increase surface energy, improving the adhesion of UV varnish, lamination, or top coatings.

Adjust the heat settings, optimize airflow, and use the correct film type based on shrink percentage requirements.

Use fast-drying inks or UV-curable inks and adjust printing pressure accordingly.

Use a suitable adhesive (pressure-sensitive or heat-activated) for better bonding.

When using BOPP (Biaxially Oriented Polypropylene) film for in-mold labeling (IML) in injection molding, several challenges may arise during printing, processing, and molding. Below is a detailed breakdown of common problems and corresponding solutions.

When using pressure-sensitive adhesive (PSA) materials in labels, various issues may arise during printing, application, and storage. Below are the most common problems and their corresponding solutions.
