What is important in printing on milk tea paper cups?

May 21,2025

The company is currently focusing on the research and development of new types of ink, such as water-based ink and UV ink, that meet environmental protection requirements for milk tea paper cup printing. Water-based inks are widely recognized as environmentally friendly printing materials for paper cups. Since water is a polar substance, water-based inks contain little to no organic solvents, as polar substances are soluble in polar media. The key feature of water-based inks is their reduced VOC emissions, which helps prevent pollution from volatile organic compounds, improves printing work environments, and benefits human health.

It completely eliminates the harm caused by certain toxic and harmful substances in solvent-based inks to human health and the contamination of paper cup packaging products. It is particularly suitable for packaging printing products with strict hygiene requirements, such as food, beverages, pharmaceuticals, and toys. Additionally, it reduces fire hazards caused by static electricity and flammable solvents and minimizes the residual solvent odor on printed products. At the same time, water-based varnishing technology is being developed. Both lamination and oil-based varnishing can cause significant environmental harm, while water-based varnishing uses diluents that are non-toxic, odorless, and non-polluting water. From the perspectives of environmental protection and human health, water-based varnishing technology undoubtedly has advantages.

Environmental protection technologies can be employed to treat exhaust gases and waste. Various by-products generated during the printing process of milk tea paper cups can be collected specifically. Valuable items such as paper can be recycled, while materials like film and plastic that are difficult to decompose and pose environmental risks can be processed through cost-effective methods by waste recycling stations or sanitary landfilling. At present, due to production requirements, it is still necessary to use various printing materials that may release harmful or toxic gases during use. These gases can be treated through methods such as ventilation, adsorption, recycling, or catalytic combustion to reduce the concentration of harmful gases in the workplace, minimize their impact on human health, and reduce environmental pollution.
