Paper straws are of great significance to environmental protection and are worth promoting, but after all, plastic straws have been eliminated. If you want to popularize them, you must ensure that the cost is competitive. Under the premise of studying how to overcome known shortcomings and improve materials and processes.

The main safety risks of paper straws are: first, harmful substances that may exist during use migrate into food, such as heavy metals in inks, fluorescent whitening agents introduced or unintentionally added during the production process, Formaldehyde, etc.; second, there may be microbial contamination in the product during circulation.

In China, there are special food safety control standards for paper and cardboard, namely GB4806.8-2016 "National Food Safety Standard for Food Contact Paper and Paperboard". This standard covers raw material requirements, sensory requirements, The safety of food contact paper and cardboard is controlled in terms of physical and chemical index requirements, microbial limits, additive requirements, labeling requirements, etc.

In addition, if adhesives and inks are used in the product, they must also comply with the corresponding national food safety standards. Ultimately, it is ensured that when the product comes into contact with food under normal use, the substances migrated into the food will not harm human health, will not cause changes in the composition, structure, color, aroma and other properties of the food, and will not produce technical functions for the food.

Under normal circumstances, if the manufacturer uses production raw materials that comply with regulations, adds additives that comply with regulations, the production process is compliant, and the paper straw end products produced comply with national food safety standards, there will be no problem in circulation. pollution, then its products are generally relatively safe and consumers can buy with confidence.
