The production of plastic products should ensure the safe use of additives

recently, the European Union issued the directive prohibiting the use of bisphenol A in baby bottles (2011/8/eu), which has continued to "ferment", and the safety of bisphenol A and other plastic additives used as plasticizers has aroused widespread public concern

plastic additives, also known as plastic additives, are some compounds added during polymer (synthetic resin) molding processing to improve its processing performance or to improve the insufficient performance of the resin itself, including more than 10 types of plasticizers, heat stabilizers, antioxidants, fillers, cross-linking agents, etc. The forming process of plastic products is basically completed by such processes as mixing, plasticizing and forming, while resin, additives and processing equipment (including molds) are indispensable basic elements in the processing process. Plastic additives play an important role in improving the processing and application performance of products, such as adding plasticizers to reduce the forming temperature of resin and make products soft. At this stage, there are still hidden dangers in the use of additives in exported plastic products. According to the product monitoring data of Yuyao inspection and Quarantine Bureau's export friction and wear testing machine, also known as friction testing machine and wear testing machine, the disqualification caused by improper use of plastic additives accounts for 57% of the total disqualification of plastic products. The reason is that on the one hand, the production enterprises have a tendency of "emphasizing function and neglecting safety" in the use of plastic additives, and due to the small amount of additives used in plastic formulas, they do not pay enough attention to their use safety. On the other hand, due to the complexity of plastic additives, in addition to the complex standards and regulations of the importing countries, which are difficult for enterprises to master, ordinary enterprises also lack sufficient technical capacity to identify the compliance and safety of the purchased additives. Here, Jinan laboratory machine manufacturer introduces which eight categories objectively cause some enterprises to blindly use plastic additives, causing hidden dangers to the quality and safety of exported products

in view of this, the inspection and Quarantine Department reminded relevant enterprises: first, actively understand the requirements of foreign standards. Follow up the updates of the US federal regulations, the US FDA food contact notification list, the EU directive 2002/72/ec on food contact plastics and other relevant regulations. At the same time, strengthen the contact with the inspection and quarantine department to obtain the standard information in a timely manner. Second, pay attention to the choice of plastic additives. Products with different uses have certain requirements on the appearance, smell, pollution, etc. of the additives used. Before signing the order, the enterprise should first communicate with foreign customers to clarify the final use of the product, and select plastic additives according to the product use within the framework of the laws and regulations of the importing country, avoid using controversial additives, and actively seek to use safe alternatives. Therefore, it can be used as a reference product for the plastic mold industry. Third, strengthen the management of the use of plastic additives. Enterprises should complete Baumert added: "This is a very wise decision. We should improve the raw material procurement system, establish a stable cooperative relationship with suppliers, establish a restraint mechanism, and prevent the misuse of plastic additives with the help of suppliers' professional knowledge. At the same time, we should establish a traceability management for the use of plastic additives, control the use flow of each kind of additives, and facilitate the tracking and recall. Fourth, we should strengthen the detection of plastic additives and finished products. For additives and finished products with high risks, we should timely implement the inspection Certificate, send the products to a testing institution with technical ability for testing and analysis, and effectively control the product quality and safety risks
