Cupstock paper is a food-safe paper, suitable for both hot and cold food and beverages. Each base paper consists of 2 or 3 layers, known as ply. High quality cupstock paper has the ability to withstand liquid holdout challenges because it's laminated with PE, PLA, or Water Base solutions and is supported by one of its mechanical properties: Scott Bond. This hinders liquids from leaking, penetrating through and getting absorbed into the inner layers of the paper ply. With this attribute, cupstock paper becomes the ideal choice for paper cups, noodle and soup bowls.
