| One of the primary functions of custom cereal boxes is product protection. Cereals are dry, fragile, and sensitive to moisture and air exposure. High-quality packaging typically uses durable paperboard or cardboard combined with an inner food-grade liner, such as a plastic or wax-coated bag. This dual-layer system helps preserve freshness, prevent contamination, and maintain the crisp texture of the cereal. Proper sealing also extends shelf life, ensuring that consumers receive a high-quality product every time. |
