It is recommended to store food packaging paper boxes in a semi-sealed manner; this protects against dust and insects while allowing for slight ventilation, thereby preventing moisture accumulation and dampness caused by complete airtightness. Boxes can be placed in lidded storage bins or dust-proof bags-leaving a small gap for airflow-and kept on dry, cool shelves away from stoves, sinks, and windows. While completely airtight storage prevents dust, the lack of air circulation over time can lead to condensation due to temperature fluctuations, causing the boxes to become damp and soft; conversely, leaving them completely open exposes them to dust and grease, compromising food hygiene. Semi-sealed storage keeps the boxes clean and dry while preserving the paper's structural integrity; when stored properly, quality remains stable for 6–12 months without requiring complex storage conditions, making it a practical solution for various food service establishments.
