Is it safe to print napkins with water-based ink？
Date: Jul 17 2024 From: Star Color
The environmental characteristics of
water-based ink have been widely recognized, but paper towels come into contact with food. If the ink used to print paper towels is not safe enough, it can cause harm to human health. So, can water-based ink be used to print paper towels?
The answer is: Yes, water-based ink is a safe and environmentally friendly ink, and it can also reach food grade. After drying, even if it comes into contact with food, it will not contaminate the food or emit harmful substances. Let's analyze it in detail below.
1、 The environmental characteristics of water-based ink
Low volatile organic compounds (VOCs): The VOCs content of water-based ink is extremely low, and can even reach zero VOCs emissions, which reduces the harm to the environment and human health.
Non toxic and harmless: Water based ink uses water as the solvent and does not contain toxic or harmful organic solvents such as toluene, xylene, etc., so it will not cause harm to operators during the printing process.
Compliant with environmental regulations: Water based inks comply with increasingly stringent environmental regulations, such as the EU's REACH standard and the US FDA standard, which have strict restrictions on harmful substances in the ink.
2、 Application of water-based ink in tissue printing
Safety: Due to the non-toxic and harmless nature of water-based ink, it is particularly suitable for packaging and printing products that require strict hygiene conditions, such as tissues, napkins, etc. Printing with water-based ink on these products can ensure their safety and hygiene.
Adhesion: Although the adhesion of water-based ink may be slightly inferior to solvent based ink on some non absorbent substrates, its adhesion fully meets the requirements on absorbent substrates such as paper and tissues.
Printing effect: Water based ink can print bright and high gloss colors, making the printing effect of products such as tissues more beautiful.
3、 Precautions
Although water-based ink has high safety in tissue printing, the following points should still be noted during use:
Avoid prolonged skin contact: Although water-based ink is non-toxic and harmless, prolonged skin contact may still cause discomfort, so operators should wear protective equipment.
Maintain workplace ventilation: Although the VOCs content of water-based inks is extremely low, maintaining good ventilation in the workplace can further reduce the concentration of harmful substances.
Proper storage and handling: Water based ink should be stored in a cool, ventilated, and dry place, avoiding direct sunlight and high temperatures. The remaining ink after use should be sealed and stored in a timely manner to avoid volatilization and contamination.
Although water-based ink has many advantages and can also reach food grade, when we choose
ink for printing napkins, we must carefully check whether the ink meets food grade and whether corresponding testing reports can be provided. For example, the food grade water-based ink produced by StarColor can provide testing by the US FDA. Welcome to consult.
