How to ensure the hygienic performance of paper bowls

In the modern food packaging industry, the hygienic performance of paper bowls is directly related to the health and safety of consumers. Therefore, it is crucial to ensure the hygienic standards of each link in its production process. First of all, the selection of raw materials is the basis for ensuring the hygienic performance of paper bowls. Paper bowls are usually made of chemical wood pulp that meets food safety standards. When selecting base paper, it is necessary to ensure that it meets strict hygienic standards, especially the detection of heavy metal content, fluorescent substances and microbial indicators. For example, excessive heavy metals such as lead will not only affect the safety of paper bowls, but may also migrate into food during use, and cause potential harm to the human nervous system and blood system after long-term intake. In addition, paper bowls using recycled raw materials have a higher hygienic risk because recycled materials may carry contaminants and harmful microorganisms, increasing food safety risks.

In the production process of paper bowls, the hygienic control of the production environment cannot be ignored. The production workshop needs to be kept clean, dry, well ventilated, and disinfected regularly. Before entering the production area, staff must undergo a strict disinfection procedure and wear work clothes, hats, masks and gloves that meet hygienic standards to prevent the introduction of contaminants such as bacteria and dust. These measures can effectively reduce the risk of cross-contamination in the production process and ensure the hygienic quality of paper bowls.

The storage conditions of raw materials must also be strictly controlled to prevent them from getting damp, moldy or otherwise contaminated. The base paper should be stored in a dry and ventilated warehouse to avoid mold growth caused by high humidity. In addition, during the production process, the use specifications of raw materials must be strictly followed to ensure that each batch of materials is strictly tested and meets the corresponding hygiene standards.

The optimization of the production process is a key link to ensure the hygienic performance of paper bowls. In the production process of paper bowls, every step from die-cutting paper, bending and joining to thermal synthesis must be strictly operated in accordance with hygiene standards. In the thermal synthesis link, precise control of parameters such as temperature and pressure is crucial to ensure that the various parts of the paper bowl are tightly combined to prevent gaps or holes, thereby avoiding food leakage and bacterial growth. At the same time, the coating process of the inner wall of the paper bowl also needs to use safe and non-toxic coating materials to ensure that the coating is uniform and firm to prevent the coating from falling off during use and affecting the overall hygienic performance of the paper bowl.
