According to China Packaging Network, it is known that in recent days, the laboratory of food contact materials of State Inspection and Quarantine Bureau has continuously detected a total of 5.9 8.3 mg/m2 of residual solvents in paper-plastic, aluminium-plastic and plastic composite food packaging, which exceeds the national standard GB/T10004-2008. For this kind of packaging material with potential food safety hazards, relevant departments and enterprises need to attach great importance to it.
Our national standard GB/T 10004-2008 "Plastic Composite Film for Packaging, Bag Dry Composite, Extrusion Composite" stipulates that the total amount of residual solvents shall not exceed 5 mg/m2, and benzene solvents shall not be detected (detection limit is 0.01 mg/m2). In the superstandard products, the residual solvents detected were mostly ethyl acetate, acetone, ethanol and other volatile solvents.
According to the survey of China Packaging Net, the residual solvents in composite food packaging mainly come from various solvents used in the production process of composite food packaging printing, composite and coating. Although the toxicity of solvents such as ethanol and ethyl acetate is relatively low, the high residual solvents will affect the taste of food. Therefore, China's national standard GB/T 10004-2008 clearly stipulates the limit of the total residual solvents, especially for the more toxic benzene solvents, the strict limit of 0.01mg/m2 can not be detected. In recent years, the problem of residual solvents in food packaging bags has attracted wide attention from all walks of life. It urges manufacturers to strictly screen raw materials, improve technology and abandon benzene solvents, so that the residual solvents in composite food packaging can maintain good quality. However, with the development of national economy and the acceleration of life rhythm, the national demand for packaged food has increased substantially, and the demand for packaging materials for food production enterprises has also increased. In order to meet the demand, some food packaging enterprises work overtime and overload, only to catch up with the time and complete the production tasks, but neglect the control of residual solvents. The improper control of raw materials, insufficient drying temperature and time deviate from the process, resulting in excessive solvent residues.
Therefore, food packaging enterprises should attach great importance to the problem of excessive solvent residues. Optimize raw materials and control process to ensure solvent residue within the qualified limit. At the same time, food enterprises should strengthen the monitoring of residual solvents in incoming food packaging to prevent a large number of residual solvents from volatilizing in food processing areas, leading to food odor or contamination by solvents.
