Production of plastic products should ensure the safe use of additives
The molding process of plastic products is basically completed by the processes of compounding, mastication and molding, while the resin, auxiliary agent and processing equipment (including mold) are the essential elements in the processing process. Plastic additives are processed for plastic products. It is important to improve and improve the performance of the application, such as reducing the molding temperature of the resin, making the product soft and adding a plasticizer.
At present, the use of auxiliaries in export plastic products still has hidden dangers. According to the monitoring data of export products of Yuyao Inspection and Quarantine Bureau in 2010, the unqualified products caused by improper use of plastic auxiliaries accounted for 57% of the total unqualified plastic products. The reason is that on the one hand, manufacturers have a tendency to “heavy function, light safety†in the use of plastic additives, and because the amount of additives used in plastic formulations is small, the safety of their use has not caused enough. Pay attention to it. On the other hand, due to the complexity of plastic additives, in addition to the complexity of importing country standards and regulations, enterprises are difficult to master, the general enterprises also lack sufficient technical capabilities to identify the compliance and safety of procurement auxiliaries. Objectively, some enterprises blindly use plastic additives to cause hidden dangers to the quality and safety of export products.
In view of this, the inspection and quarantine department reminds relevant enterprises:
First, actively understand the requirements of foreign standards. Track US federal regulations, the US FDA Food Contact Bulletin List, EU Directive 2002/72/EC Food Contact Plastics and other related regulations. At the same time, it is necessary to strengthen contact with the inspection and quarantine department to obtain standard information in a timely manner.
The second is to pay attention to the choice of plastic additives. Products with different uses have certain requirements on the appearance, smell and pollution of the auxiliaries used. Before signing an order, the company should first communicate with foreign customers to clarify the final use of the product and within the framework of the importing country’s regulations. Product use Choose plastic additives, avoid the use of controversial additives, and actively seek to use safe alternatives.
The third is to strengthen the management of the use of plastic additives. Enterprises should improve the procurement system of raw materials, establish stable cooperative relations with suppliers, establish a restraint mechanism, and use the expertise of suppliers to prevent misuse of plastic additives. At the same time, traceability management of plastic additives should be established to control the flow of each additive to facilitate tracking and recall.
The fourth is to strengthen the testing of plastic additives and finished products. For auxiliaries and finished products with higher risks, verification should be carried out in time, and the products should be sent to the testing institutions with technical capabilities for testing and analysis to effectively control product quality and safety risks.
