In the process of food packaging box printing, it is crucial to avoid pollution to ensure the safety and hygiene of food packaging.
Here are some key measures to avoid pollution:
1. Choose environmentally friendly and safe printing materials
Ink selection:
Use environmentally friendly inks, such as water-based inks, UV inks, etc. These inks have lower VOC (volatile organic compound) emissions than traditional solvent-based inks, and are less harmful to the human body and the environment.
Avoid using inks containing heavy metals (such as lead, chromium, mercury, etc.) and other harmful substances, which may migrate into food and cause harm to human health.
Paper and plastic materials:
Choose paper and plastic materials that meet food safety standards to ensure that they are non-toxic, odorless, corrosion-resistant, and will not react chemically with food.
2. Strictly control the printing process
Cleaning and maintenance:
Before printing, thoroughly clean the printing equipment to ensure that there are no residues or contaminants.
Regularly maintain and service the printing equipment to prevent pollution caused by equipment aging or failure.
Operating specifications:
Establish strict printing operating procedures to ensure that operators operate in accordance with the specifications and avoid contamination caused by improper operation.
During the printing process, pay attention to controlling the amount of ink and drying time to ensure that the ink is fully dried and reduce the migration of residual solvents.
3. Strengthen quality control and safety testing
Printing sample testing:
Before formal printing, test the printing samples to check whether the quality of the printed products meets the requirements, especially in terms of color, clarity, position, etc.
Safety testing:
Carry out safety testing on printed products, including testing the content of ink and other chemicals that may migrate into food to ensure that they meet food safety standards.
Use professional testing equipment and methods, such as gas chromatography, liquid chromatography, etc., to assess the migration risk of ink.

4. Comply with relevant laws and standards
Comply with laws and regulations:
Comply with national and local laws and regulations on food packaging printing, such as GB 9685 "Hygiene Standards for the Use of Additives in Food Containers and Packaging Materials".
Pay special attention to the directives and standards on food packaging material safety in countries and regions such as the European Union and the United States to ensure that products can be exported to these markets.
QS standards:
For packaging materials that are in direct contact with food, the country has mandatory QS (Quality Safety) standards.
Enterprises should ensure that the packaging materials used meet the requirements of QS standards.
5. Improve environmental awareness and training
Environmental protection publicity:
Strengthen the publicity and education of environmental awareness within the enterprise and improve employees' awareness of the importance of environmental protection.
Employee training:
Regularly train employees on food safety and environmental protection to improve their professional quality and operational skills.
