In today's environmentally conscious world, it is important to consider the impact of our actions on the planet. This includes the printing industry, where the choice of ink can make a significant difference. In this article, we will explore the basics of eco-friendly ink for paper bag printing and why it is a crucial consideration for businesses.

Due to the improvement of people's living standards and the improvement of both material and spiritual needs. Food and items are packaged extremely beautifully, and more and more paper bags are printed with various information labels to attract users' attention. Therefore, paper bag printing has gradually become one of the factors affecting physical health and the environment.
Especially if food is to be packaged directly, the ink should not contain substances harmful to the human body. The state has strict regulations on food paper bags. The printed ink must be completely solidified after printing, and there must be no solvent residue.
The printing industry has long been associated with high levels of waste and pollution. Traditional printing inks contain harmful chemicals and solvents that can have a detrimental effect on the environment. However, with the increasing demand for sustainable practices, eco-friendly ink options have emerged as a viable alternative.

The impact of ink on the environment

Traditional printing inks contain volatile organic compounds (VOCs) that are harmful to both human health and the environment. These VOCs contribute to air pollution and can cause respiratory problems. Additionally, the production and disposal of traditional inks often involve the use of hazardous chemicals, further exacerbating their environmental impact.

What eco-friendly ink for paper bag printing?

Eco-friendly ink for paper bag printing refers to inks that are made from non-toxic, renewable, and biodegradable materials. These inks are designed to minimize harm to the environment while still providing vibrant and long-lasting prints. Nowadays, there are generally three types of eco-friendly series of inks widely used by China printer:

1. Water-based ink

Water-based ink is one of the most popular choices for eco-friendly paper bag printing. It is made from a combination of pigments, binders, and water.

UV curable inks do not release any harmful VOCs and are free from solvents. They also offer excellent adhesion to various substrates, ensuring long-lasting prints that resist fading and smudging.
Compared with traditional inks, UV-curable inks polymerize and dry more thoroughly without any evaporative or solvent contaminants. It has the characteristics of good dispersion, good leveling, strong tinting power, small UV absorption under light irradiation, and no hindrance to polymerization reaction.
