In the field of food packaging, food paperboard plays a vital role. Understanding its main components can help us better understand the characteristics and advantages of this type of paper.
Food paperboard usually uses 100% virgin wood pulp as the main raw material. This virgin wood pulp is processed through multiple processes, including pulping, pulping, papermaking, etc. to ensure the quality and safety of the paper. Since no recycled fiber is added, food paperboard does not have hidden dangers such as residual chemicals that may endanger food safety.
In addition to virgin wood pulp, food paperboard will also add an appropriate amount of additives during the production process to optimize its performance. For example, in order to enhance the strength and toughness of paper, a small amount of natural enhancer will be added; in order to improve the printing adaptability of paper, environmentally friendly coatings suitable for food packaging will be added. These additives are strictly screened to ensure that they meet food safety standards and will not cause any harm to human health.
In addition, the raw material wood pulp of food paperboard needs to be strictly controlled in both the source and processing process. Wood pulp comes from high-quality wood, such as coniferous wood pulp, which is less polluted during its growth. During the pulping and papermaking process, the production environment is kept clean and hygienic, and the production process strictly follows the Good Manufacturing Practice (GMP) to prevent harmful substances from entering the paper from the source.
Food cardboard is of great significance to food safety. It can not only carry food information, but also directly or indirectly contact food. Its safe and hygienic characteristics enable it to be widely used in food packaging, providing a strong guarantee for consumers' food safety.
