1. Compliance with relevant standards and regulations
To test the hygienic performance of Color Blister Tray, we must first follow relevant standards and regulations. Different countries and regions have strict regulations on food contact materials, pharmaceutical packaging, etc., such as the relevant directives of the European Union, the standards of the US FDA, and my country's GB 4806 series of standards. These standards clearly define the limit requirements for various types of harmful substances, such as the maximum allowable content of heavy metals (lead, cadmium, mercury, etc.), the migration limit of specific chemical substances (such as phthalate plasticizers), etc. Manufacturers must be familiar with and strictly abide by these standards and use them as the basic basis for testing and quality control.
2. Hazardous Substance Migration Test
To ensure that the Color Blister Tray does not release harmful substances, migration testing is the key. The tray is exposed to a specific simulant (if used for food packaging, it may be water, ethanol, acetic acid, etc., to simulate the characteristics of different types of food) under specified temperature and time conditions, and then the simulant is tested for harmful substance migration. For example, high performance liquid chromatography (HPLC) is used to detect organic pollutants that migrate into the simulant, and atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS) is used to detect heavy metal elements. By precisely controlling the test conditions, such as the contact temperature simulating the storage and transportation environment temperature in actual use, and the contact time covering the longest time that the pallet may be in contact with the items, the risk of harmful substance migration can be accurately assessed.
3. Volatile organic compound (VOC) detection
Color Blister Tray may release volatile organic compounds, which is also an important factor affecting hygienic performance. The headspace-gas chromatography-mass spectrometry (HS-GC-MS) can be used to detect the type and content of VOCs released by the tray at a certain temperature. During the test, the tray is placed in a sealed container, and after balancing at a specific temperature for a period of time, the top air is extracted for analysis. In this way, common volatile organic compounds such as benzene, toluene, and xylene can be detected to ensure that their content is within a safe range to avoid contamination of the packaged materials or harm to human health.
4. Control of raw materials and production process
In addition to finished product testing, control of raw materials and production processes is also an important link to ensure hygienic performance. When purchasing raw materials, suppliers are required to provide certification documents that meet hygienic standards and conduct random inspections. During the production process, avoid using additives that may contain harmful substances, such as certain pigments and lubricants that do not meet regulations. At the same time, ensure the cleanliness and hygiene of the production environment to prevent the introduction of pollutants during the production process. For example, the production workshop should maintain proper ventilation conditions to prevent oil, dust, etc. on the production equipment from contaminating the tray. Improve the hygienic performance of the Color Blister Tray through strict control from the source to the entire production process.
