Discussion on the food safety of PVC fresh-keeping film. Whether it is a professional statistical analysis organization, food manufacturers or consumers who have stopped grouping patterns, they all have doubts about this: fresh-keeping film is directly used to package food, so will it produce substances harmful to human body when it is used in freezing, heating and microwave oven

in response to this problem, in late May, the president of the European Association of polyethylene film manufacturers (EPFMA) and the French linparker plastic pontiway company, a professional European manufacturer of fresh-keeping film, communicated with all relevant personnel of the General Administration of quality supervision, inspection and quarantine and the Shanghai Municipal Health Bureau on the production regulations and technical standards of fresh-keeping film

the European Association of polyethylene film manufacturers was established in 1976, representing the union of European PVC film producers. It works with the European Commission to study and formulate regulations on film production, and is committed to promoting the improvement of product quality and the innovation of production technology

epfma association chairman introduced the production of PVC fresh-keeping film in Europe in detail at the exchange meeting. 1. Equipment name: impact experiment low-temperature tank regulations and quality standards:

the fresh-keeping film used in various foods is different. The higher the oil content of food, the stricter the restrictions on the fresh-keeping film. Because the additives in the fresh-keeping film interact with the oil, so, At present, most of the fresh-keeping films on the market can not directly package high-fat food

in Europe, there are very strict regulations to define different kinds of fresh-keeping films used for different foods and give them a special number. For example, No. 4 fresh-keeping film for packaging ordinary meat, sausage and frozen food cannot be used for packaging butter, cream and other foods; No. 1 fresh-keeping film, which can be used for cooking in microwave oven, can pack all food. EPFMA Association and relevant European administrative departments will regularly spot check the fresh-keeping film in supermarkets and other places. If the selected fresh-keeping film does not meet the standards of corresponding laws and regulations, the manufacturer of the fresh-keeping film will be disqualified from the membership of EPFMA Association, which means that this kind of fresh-keeping film has lost the guarantee of food safety

the current European regulations on packaging materials in direct contact with food are: 89/109/eec, 90/128/eec, 82/711/eec and 85/572/eec, in which 90/128/eec specifies the mobility limit of substances in plastic packaging materials: 60mg/kg or 10mg/d ㎡ + -3 of food. The migration amount of substances in the fresh-keeping films produced in South Korea, Japan, Taiwan and Thailand exceeds the above standards. Therefore, for the sake of food hygiene and human health, the fresh-keeping films produced in these places cannot be sold in the European market

there is a special laboratory lne in Europe to test the safety of PVC fresh-keeping film microwave oven. The test is to measure whether the migration of substances in the fresh-keeping film meets the regulations under simulated conditions (simulated food, temperature and time) according to the provisions of European regulations. The most important thing about the preservative film used in microwave oven is to measure whether there are substances in the preservative film that migrate into the food and pollute the food under the condition of high temperature, that is, when the food is heated or even cooked together with the preservative film. For example, the triolin microwave oven fresh-keeping film produced by the French company linparker has been proved to be able to withstand a high temperature of 175 ℃ for up to 1 hour, that is, in daily microwave cooking, there will be no substances harmful to human body entering the food

compared with the U.S. FDA standard, European regulations pay more attention to the impact of substances in food packaging materials on food, that is, the direct impact on human health, while the U.S. FDA standard pays more attention to the impact of food packaging materials on nature

European regulations have always been the most stringent in terms of food safety and public health. Recently, the EPFMA Association and the legislative body of the European Commission are discussing to establish more stringent regulations on the mobility of food packaging materials in direct contact in 2004, that is, restrictions on the use of plasticizer ingredients (drha) in materials. At that time, the mobility limit of 10mg/d ㎡ + -3 in 90/128/eec will be further tightened. French linpak company has always been at the forefront of the fresh-keeping film manufacturing technology. In May this year, they have fully launched the latest special fresh-keeping film for fat food, that is, the fresh-keeping film with DEHA migration of only 3mg/d ㎡. This kind of fresh-keeping film has reached the standard of the new European laws and regulations to be issued in 2004. Other European fresh-keeping film manufacturers will follow suit and jointly launch new standards

At the exchange meeting, the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China and the food hygiene department also introduced China's industrial standards and management systems in this regard, enabling European representatives to have a clearer understanding of China's current regulations and management methods

relevant departments in China are expected to have an annual output of 100000 tons and are very interested in this exchange activity, especially the strict requirements of European countries on food packaging hygiene, and the good communication and cooperation between industry associations and government legislatures. Both sides hope to further maintain close contact, strengthen cooperation and exchange needed goods on the basis of this exchange

through this exchange, we can see that in Europe, PVC fresh-keeping film is a widely used food packaging product due to very strict regulations and testing system; In China, with the further improvement of laws and regulations in this area and the further standardization of management, the fresh-keeping film of PVC materials will give full play to its superior performance in all aspects and occupy an important position in the field of food packaging
