The main safety risks of paper straws are: first, harmful substances that may exist in the process of use migrate to food, such as heavy metals in ink, fluorescent brighteners brought in or unintentionally added in the production process, formaldehyde, etc. Second, there may be microbial pollution in the process of product circulation.
China has a special food safety control standard for paper and paperboard, namely GB4806.8-20 16 "National Food Safety Standard for Food Contact Paper and Paperboard", which controls the safety of food contact paper and paperboard from the aspects of raw material requirements, sensory requirements, physical and chemical indicators requirements, microbial limit, additives requirements and labeling requirements.
In addition, if adhesives and inks are used in the products, they should also meet the corresponding national food safety standards. Finally, it is guaranteed that when the product comes into contact with food under normal use, the substances that migrate into the food will not harm human health, will not change the composition, structure, color, flavor and other properties of the food, and will not have technical functions on the food.
Under normal circumstances, if the production enterprises use raw materials that meet the requirements, add additives that meet the requirements, the production process is compliant, the paper straw terminal products produced meet the national food safety standards, and the circulation links are pollution-free, then the products are generally relatively safe, and consumers can buy them with confidence.
