Suitable for manufacturing paper cups, food packaging boxes, and disposable tableware, providing safe, hygienic, and eco-friendly solutions for the food industry.
Can it be used for both hot and cold drink cups?
Yes. The base paper is treated with a PE waterproof coating, allowing it to maintain stiffness in cold drink environments (0–4℃) and preventing softening or collapse from condensation. It is also heat-resistant up to 95–120℃, suitable for beverages above 85℃ such as coffee and hot tea, without delamination or leakage. This makes it fully suitable for producing disposable hot and cold drink cups.
Is color printing supported?
Yes. The paper has excellent print adaptability, supporting high-definition offset printing, flexographic printing, and UV spot coating. Printed designs achieve abrasion resistance up to grade 4, ensuring durability and vibrant presentation.
