Many hotels and high-end restaurants use customized napkins with exquisite patterns printed on them, which not only make the users feel happy, but also have a certain promotional effect on the brand. However, some people may have concerns about the safety of the ink used for the patterns and text printed on them. Nowadays, most napkins are printed with water-based ink. So, are water-based ink napkins toxic? Today we will delve into it in depth.

Composition analysis of water-based ink

Water based ink mainly uses water as the solvent, which is also the key difference between it and traditional solvent based ink. In addition to water, its main components include water-based resins, pigments, additives, etc. Water based resin is the film-forming substance of ink, which can evenly disperse pigments and form a protective film after drying, fixing pigments on the surface of napkins. Pigments give ink various colors and are used to print exquisite patterns and text. There are various types of additives with different functions. For example, some additives can adjust the drying speed of ink, some can improve the fluidity of ink, and some can enhance the adhesion between ink and napkins.

The key point is that most of these ingredients are non-toxic and harmless. Unlike traditional solvent based inks that contain organic solvents such as benzene, toluene, and xylene, water-based inks do not contain volatile organic compounds (VOCs) that are harmful to human health. Water based resins are typically made from natural or synthetic polymer materials and do not release harmful substances under normal usage conditions. Pigments are often selected from types that meet food safety standards. These pigments undergo strict screening and testing and will not migrate to the surface of napkins, thus avoiding harm to the human body.

Related standards and regulations

In terms of food safety and hygiene, the country has strict standards and regulatory systems. For napkins that come into direct contact with food, the safety of their printing ink is of particular concern. When producing water-based ink for napkin printing, it must comply with relevant national standards and industry specifications. For example, there are clear limit requirements for indicators such as heavy metal content and harmful substance migration in ink. Production enterprises need to conduct strict quality inspections to ensure that water-based ink does not have adverse effects on the hygiene performance of napkins during use. Regulatory authorities will also conduct regular spot checks on napkin products in the market. Once products that do not meet the standards are found, they will be dealt with in accordance with the law to protect the rights and health safety of consumers.

Actual application situation

From practical applications, water-based ink has been widely used in napkin printing. Many well-known napkin manufacturers have adopted water-based ink printing precisely because of its environmentally friendly and safe characteristics. During normal use, we use such napkins to wipe our mouths and come into contact with food without any discomfort or health issues. Moreover, with the continuous advancement of technology, the performance of water-based ink is also constantly optimized, and its safety and stability in napkin printing have been further improved.

Water based ink napkins are non-toxic and can be used with confidence. Water based ink has become an ideal choice for napkin printing due to its environmentally friendly and safe characteristics. It not only meets consumers' needs for health and environmental protection, but also conforms to the trend of sustainable social development
