Seminar on the safety of the hottest food packagin

The seminar on food packaging safety and new materials, new technology

the seminar on food packaging safety and new materials, new technology was held in the hotel on August 2 and 3, 2009. The conference was hosted by Huang Qihong, executive vice president of Guangdong Packaging Association, delivered a welcome speech at the conference

food packaging is called special food additive. Mr. dongjinshi, Secretary General of the International Food Packaging Association, made a speech entitled "Hygienic standard for the use of additives in food packaging containers and packaging materials" at the meeting, explaining the terms and definitions in the standard, the principles for the use of additives in food containers and packaging materials, the determination of specific migration, examples of several commonly used additives, and example questions, It also mentioned the regulations on the use of non listed national reference materials. Mr. Dong said that compared with the original standard (gb9685 2003), the new standard of the hygienic standard for the use of additives for food containers and packaging materials (gb9685 2008) has expanded the approved varieties of additives from dozens of varieties in the original standard to 959 kinds, changed the additives in the original standard into additives, and listed the list of permitted additives, Chemical Abstract registration number, scope of use, maximum amount of use Specific migration or maximum residue and other restrictive requirements. The standard has made clear provisions on plasticizers, tougheners, curing agents, initiators, accelerators, antioxidants, flame retardants, and related adhesives, inks, pigments, etc. used in plastics, paper products, rubber and other materials used in food contact. At present, China's requirements for the health and safety performance of printing inks mainly focus on the testing of heavy metals, solvent residues, polycyclic aromatic hydrocarbons, polybrominated biphenyls and other items. However, the latest version of gb/t10004 2008 composite film for packaging, bag dry compounding and extrusion compounding standard implemented on August 1, 2009 stipulates that the total amount of solvent residues is 5mg/m2, Benzene solvents shall not be detected (in this new standard, toluene is not on the list of 959 additives allowed to be added, that is, food packaging will never be allowed to detect toluene). The new standard also clearly emphasizes that substances not specified in the list shall not be used in containers and packaging materials for food processing. Mr. Dong pointed out that the "Hygienic standard for the use of additives for food containers and packaging materials" (gb9685 2008) is a mandatory national standard. The amount of additives in food containers and packaging materials used in food packaging materials shall not only comply with the provisions of the standard, but also comply with the provisions of the corresponding national health standards for food containers and packaging materials

Su Chuanjian and Zhang Liming from the national printing and decoration products quality supervision and inspection center elaborated on the national executive standards stipulated in the food packaging production license. It is mentioned that in terms of food plastic packaging regulations, among the conditions that enterprises applying for production licenses should meet (on-site inspection methods), the inspection conclusion of plastic packaging is based on:

among the 53 inspection contents, 8 items, including production facilities, equipment and tooling, raw and auxiliary material procurement, process management, packaging identification, and safety production, are rejected

qualified judgment (it is qualified in one of the following two cases):

1. There are no more than 8 general unqualified items, no serious unqualified items, and no veto items

2. There is no more than 1 serious nonconformity and no more than 6 general nonconformities, and there is no veto

unqualified judgment (unqualified in one of the following three cases):

1. More than 2 serious unqualified items

2. More than 9 general nonconformities

3. One or more items are rejected

Mr. dongjinshi, Secretary General of the International Food Packaging Association, suggested that domestic food packaging container, packaging material additive production enterprises, relevant food packaging production enterprises, as well as food production enterprises and operators should learn and understand relevant policies, regulations and standards in a timely manner, strengthen technical research and development, improve their product competitiveness, and reduce the risks caused by blind production

the implementation of the hygienic standard for the use of additives for food containers and packaging materials (gb9685 2008) should have a great impact on the industry and is likely to bring about a reshuffle. At the symposium, fanjiaju, chairman of New Oriental ink group, believed that China's flexible packaging industry has entered a new era of comprehensive use of benzene free ink and the application of environmental friendly benzene free ketone free composite ink. Xu Jianming, chairman of Suzhou Zhongya Ink Co., Ltd., introduced the development and application of green ink. Xiewenbo, technical director of Sano International Co., Ltd., delivered a speech on (through) rational selection of high-quality packaging materials to ensure food safety. Liu Xiong, the technical manager of Jiangmen Toyo Ink Co., Ltd., made a difficult answer to the question of how to improve the transferability, scraping and practical application technology of benzene free and ketone free environmental friendly ink, and said: Jiangmen Toyo ink is willing to provide more technical support for the majority of flexible packaging enterprises and contribute to creating a standardized and environmental friendly packaging industry. Also speaking at the meeting were Chen Jifei, technical manager of Dow Chemical polyolefin products department, who flew the energy to impact the friction resistance consumed by the pendulum in the process of one swing, Zhu Jing and Chen Xin, chemical engineers of ExxonMobil, Feng Xinping, general manager of European and American Chemistry, and so on. The discussion on how to adapt to the requirements of new regulations and how to adjust according to relevant standards was extensive and in-depth

the hygienic standard for the use of additives for food containers and packaging materials (gb9685 2008) clearly stipulates that toluene cannot be used in food packaging materials, or at least, toluene and butanone can no longer appear in products. For packaging enterprises, we should first pay attention to the selection of ink. The second is the control of solvent residue: for flexible packaging plants, there are many factors that cause the solvent residue to exceed the standard (with peculiar smell), such as raw materials and substrates, ink quality, ink release and the thickness of inking, the quality and coating amount of adhesives, the purity and proportion of organic solvents and the consistency with substrates, which will affect the solvent residue. Through this meeting, we can accurately grasp the changes of policies and standards, and clarify the direction for solving the problem of solvent residues caused by solvent based inks and adhesives in the future, and how to ensure that products meet national standards. It is beneficial for our factory to actively respond to the standards and find its own position in the fierce market competition

in terms of law, production must comply with the regulations. In terms of theory, it is the bounden duty of our employees in the packaging industry to control solvent residues and ensure food safety
