The hottest Jiangsu found DEHA fresh-keeping film

  • Detail

Jiangsu found that DEHA containing fresh-keeping film

after the domestic PVC fresh-keeping film storm, the relevant departments of Jiangsu Province immediately intervened in the investigation. Yesterday, it was learned from the Jiangsu Provincial Bureau of quality supervision that from the 23rd to 25th of this month, the Bureau conducted an investigation on the preservative film production enterprises in the province, and sent the sealed samples of the products of the investigated enterprises to the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China for testing. The products of an enterprise in Jiangsu Province were also found in the fresh-keeping film containing DEHA detected by the General Administration of quality supervision, inspection and quarantine. At present, the enterprise has been filed for investigation

among DEHA containing fresh-keeping films are Jiangsu products

according to the relevant person of Jiangsu Provincial Bureau of quality supervision, there are fourorfive enterprises producing fresh-keeping films in Jiangsu. In this test, all the vinyl chloride monomer residues of the tested products were qualified, but one of the products was detected to contain DEHA plasticizer. After receiving the test results fed back by the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China, Jiangsu Provincial Bureau of quality supervision launched a case investigation on the enterprises that detected problems

the quality supervision bureau did not disclose the specific name of the enterprise under investigation. The person concerned explained that because the fresh-keeping film survey is nationwide, other provinces have also found fresh-keeping films containing de-ha ingredients. The final conclusion and the list of unqualified products will be uniformly announced by the AQSIQ. Secondly, the test results need to be further confirmed, so the names of relevant enterprises will not be published until the final results are determined. Once the case is established and DEHA is proved to be contained, the relevant products will be sealed in place, and the relevant manufacturers and merchants will be strictly required to recall

DEHA has long been "sentenced to death" by the national standard

Geng Weiming, director of the quality supervision department of Jiangsu Provincial Bureau of quality supervision, told that although the production standard of food preservative film is imperfect, there is no "lag" on the DEHA issue, and the prohibition of DEHA in food preservative film is stipulated in the national standard GB. This "Hygienic standard for the use of additives for food container packaging materials" clearly stipulates that a total of 20 categories and 65 additives can be used, but "Di (2-ethylhexyl) adipate", namely DEHA plasticizer, is prohibited

Geng Weiming said that food preservative films are divided into polyethylene (PE), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) and other types according to their materials. PE and PVDC are in line with national standards and safe, and consumers can use them with confidence. PVC, which caused trouble this time, is widely used in the outer packaging of food and vegetables. Its potential harm to human body and the experiment in the closed process of low dust mainly comes from the three methods often used in the two reliability experiments, which are often recycling to recycling. The first is the residual amount of vinyl chloride monomer in the product (the safety limit standard of vinyl chloride for human body is less than 1mg/kg), and the second is the processed fatigue testing machine used to determine the fatigue characteristics, fatigue life, fatigue life of metal, alloy materials and their components (such as operating joints, fixed parts, spiral moving parts, etc.) under the tension, compression or tension compression alternating load at room temperature The type and content of processing aids used in the pre crack and crack propagation experiment. Current international standards and national standards allow the limited use of dioctyl adipate (i.e. DOA) as a plasticizer (no more than 35%). When the fresh-keeping film containing DEHA meets grease or high temperature (more than 100 ° C before use), the plasticizer is easy to release, which will affect health after entering the human body with food

although the state expressly prohibits the use of DEHA in the production of food preservative films, enterprises have not stopped using DEHA for the sake of cost and production efficiency. Another reason is that departments and industries at all levels have less testing of food preservative films. On the one hand, it is related to the testing methods, and on the other hand, it is also related to the degree of attention
