The food packaging industry is facing the test of new standards

the EU has promulgated and implemented the 2002/72/EC clause, which has strict restrictions on the mobility of substances contained in plastic products used in food packaging. Therefore, plastic processing plants engaged in the food packaging industry need to re inspect and analyze whether their processed products meet this requirement

the newly issued and implemented provisions related to the safety of food packaging in the EU not only strengthen cooperation, but also require all food plastic packaging products imported to EU countries to comply with this provision. This EU Basic Law on materials in contact with food, that is, a mandatory industry regulation, is error free, carefully understand some of their indicators, and rest assured standards for operational safety. It requires that food packaging materials will not harm human health, that is, packaging materials are not allowed to contain a large amount of exudable substances, which are migrated to food, resulting in harm to human health, At the same time, the whole processing link of packaging products is also required to be in a good environment

according to the "mobility limit standard (SML)", many substances are included in the restricted list. It expressly stipulates that under specific circumstances, a certain substance is allowed to migrate from plastic products to milligrams within 1kg of food

whether the packaging materials meet the requirements of the standard is generally based on the experimental test data, but the European Commission has agreed to adopt a strict judgment mode, that is, to measure and calculate the maximum possible mobility. The extra testing work is time-consuming and costly. In order to help the packaging and processing industry achieve this goal, special chem (Paris, France), which provides technical services for various plastic products and additives, together with two other cooperative institutions, provides rapid mobility calculation software. The other two institutions are Pira international business consulting and testing company in the UK and fabes Research Institute in Germany (Munich). The software system is said to have been approved by the European Commission

fabes specially developed this set of calculus evaluation system called migratepass based on the accurate laboratory migration research topic. As long as the plastic processing plant clicks on the station of this system and inputs parameters such as resin type, physical structure shape of packaging, amount of additives and fillers, packaging thickness, processing temperature and time, as well as the category of packaged food, the calculation results will be obtained, Finally, a "mobility report of Leeper in Kingsport, Tennessee" was obtained, and the test report of "mobility limit standard (SML)" was clearly given. After comparison, we can judge whether the packaging products meet the standards formulated by the European Union. Each test costs about 100 euros

migratepass system is currently only limited to the detection of single-layer packaging materials, and the EU hopes to achieve the detection of the mobility of multi-layer composite materials within two years. The European Union excluded PVC materials from this test. At present, the types of materials that can be tested include PE, PP, PS, pet, Pa. according to the Bridge Engineering Institute of the University of buffalo, inks and coatings are not considered
