Friends engaged in food-related businesses should all be concerned about one question: The packaging paper used to hold food (that is, food-grade packaging paper) - how can we ensure that the quality of each batch is the same, without problems such as uneven thickness, easy breakage, and unpleasant odors? Actually, the core is very simple - from raw materials to finished products, every step must be closely monitored, without being lazy or compromising. Today, I will explain this clearly in plain language to make you feel at ease when purchasing and using it.
First and foremost, we must start from the source. The raw materials cannot be of poor quality. For our food-grade packaging paper, the pulp used must either be virgin wood pulp or recycled pulp that meets standards. We absolutely cannot use those miscellaneous materials that may contain harmful substances. Moreover, both the pulp itself and the additives added during production must be food-grade. They must not have any unpleasant smell or harmful components. After all, this paper will come into contact with food, so safety is always the top priority. Just like when we buy vegetables, we choose fresh ones. The raw materials for making packaging paper also need to be carefully selected. If the raw materials are poor, no matter how much processing is done later, it won't be of any use.
Then comes the production process, which is the key to ensuring stable quality. During the production, the concentration of the pulp, the fineness of the fibers, all need to be controlled properly. They cannot be too thin this time and too thick the next time. Otherwise, the produced paper will be either thick or thin, and when used, it will either be too brittle or too flimsy. There is also the drying stage. The temperature and time must be precisely controlled. If the drying is too dry, the paper will become brittle and prone to breaking; if it is too wet, the paper will easily get moldy, deform, and may also affect the subsequent printing. If it is packaging paper that needs to be oil-proof and waterproof, the coating must be applied evenly. It cannot be thick in some areas and thin in others. Otherwise, when packaging oil-containing snacks, the oil will seep out, affecting the use.
In addition, the production environment is also very important. The production workshop for food-grade packaging paper must be kept clean and should not have too much dust. If dust adheres to the paper, it will no longer meet the requirements for food packaging. Moreover, the temperature and humidity in the workshop also need to be controlled properly. If it is too humid, the paper is likely to absorb moisture and become soft. If it is too dry, it may become brittle. All these factors will affect the stability of the paper quality. And the operators also need to pay attention to hygiene and avoid any human contamination. After all, this is for packaging food, and nothing can be careless.
Finally, and most importantly, comes the inspection step. For each batch of paper produced, a sample inspection is conducted to check if the thickness is uniform, if the strength is sufficient, if there is any odor, and if there are any harmful substances. It is also necessary to test for compliance with food contact standards. If even one batch is found to be不合格, it cannot be released from the factory. It needs to be reworked. Only in this way can we ensure that every roll of food-grade packaging paper that everyone receives has the same quality and is safe to use.
In summary, ensuring the quality stability of food-grade packaging paper is not very complicated. It merely requires "qualified raw materials, meticulous processing, clean environment, and strict testing".
