30% of food deterioration is caused by packaging loopholes

dongjinshi, a packaging expert, exposed that 60% of food packaging had potential safety hazards

after CCTV reported that the qualified rate of sampling inspection of food packaging bags in various places was only 50% ~ 60%, and the benzene residue exceeded the standard, the Nestle milk itx penetration incident on the 22nd of last month exposed Tetra Pak packaging materials' potential safety hazards globally for the first time. In the face of the food packaging safety problem that has exposed the tip of the iceberg, on the 30th of last month, dongjinshi, deputy director of the Committee for the comprehensive utilization of packaging resources, processed the real gold plate with the phase change package thermal insulation and energy storage technology, disclosed publicly for the first time in an exclusive interview that 30% of the deterioration events of food within the shelf life were caused by the defects of packaging materials

60% of food packaging materials have hidden dangers

the spot check results of food packaging (film) released by the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China in 2004 show that the unqualified rate of sampling inspection of special food packaging bags is as high as 15%. The main problems are that the health indicators do not meet the national standards and the physical and mechanical properties of the products are poor. The food packaging manufactured according to the traditional process inevitably contains solvents of benzene, toluene and other harmful substances. Although most of them volatilize during the manufacturing process, a small amount of solvents will remain between the composite films. With the passage of time, they will penetrate into the food from the film surface, causing it to deteriorate and taste

according to Dong Jinshi's analysis, in terms of plastic packaging, some enterprises replace food grade plastics with industrial grade plastics, adding excessive filling materials or toxic substances such as waste materials and paraffin; In the aspect of paper packaging, waste paper is used on the paperboard, industrial composite film is used, artificial whitening agent is added, and printing ink penetrates into food; In terms of composite packaging, the barrier performance of hazardous substances can not meet the requirements, and the barrier materials used by many enterprises do not have oil barrier performance. At present, about 30% of the food deterioration events during the shelf life inspection are caused by food packaging materials, and about 60% of the food packaging materials have potential safety hazards

hygiene licensing has become a regulatory gap

dongjinshi believes that the potential safety hazards of food packaging mainly come from three aspects: first, the standards are extensive or lagging behind. Most of the existing food packaging standards are extensive, and the concept is vague. Some standards have relatively low requirements for relevant indicators. For example, in the PVC fresh-keeping film incident, there were only hygienic standards for plastic molded products, but there were no relevant standards for the use functions of specific products, resulting in confusion in product quality. Second, there are problems in policy orientation. The policy on the development of food packaging materials or packaging container industry is still unclear. The regulatory functions of industry and commerce, quality inspection, health and other departments are absent from time to time. For example, at the initial production of food packaging production enterprises, the quality inspection department failed to effectively intervene in the supervision. Especially after 2000, the health licensing supervision function retained by the health department was withdrawn from the production field, and there was no health licensing management. Third, the production enterprises have poor self-discipline. Manufacturers do not understand the policies and regulations and blindly produce. As long as they receive orders at appropriate prices, they do not care what customers pack. The packaging produced is either not marked with the manufacturer or is marked indiscriminately

compulsory certification of food packaging materials next year

"from next year, China will implement compulsory certification of safety and environmental protection for food packaging materials". Dongjinshi disclosed that the food packaging to be certified mainly includes plastic products, paper products, composite packaging, metal packaging, glass packaging, etc., including 21 categories and 139 kinds of PolyOne products. PolyOne also recently announced the financial statements for the second quarter and the first half of 2016. Next year, PolyOne will take the lead in carrying out compulsory certification for plastic packaging, paper packaging and composite packaging in the food and beverage industry

citing relevant data from China Packaging Association, Dong Jinshi said that there were more than 10000 food packaging production enterprises nationwide, and only more than 100 applied for safety certification. At present, 20 food packaging enterprises have passed or will pass 3C certification. It is predicted in the industry that once the food packaging materials are installed 5 and the low temperature is set: see the operation manual of TCC intelligent temperature controller for compulsory certification, the manufacturers of poor quality packaging materials will be severely punished
