Shanghai quality supervision of new polyethylene resin

Recently, the Shanghai food contact material of polyethylene resin for special supervision and inspection, through the development of risk monitoring, the city is the production of food packaging film of polyethylene resin material bag, part of the enterprise does not meet the national mandatory standards of polyethylene film class paper cups andtableware and other food related products. Shanghai Municipal Quality Supervision Bureau immediately organized a polyethylene resin used as raw material for the production of food enterprises related products special supervision and inspection ofcontact within the scope of use of food sampling, key enterprises to use the resin raw materials and products, and on-site inspection of the production of raw materialsprocurement, production process and inspection records.

This special supervision and inspection, sampling a total of 95 enterprises in 192 batches of 111 batches of raw materials, including resin and resin raw materials for the production of 81 batches of products, after testing, products are all qualified, there are 11 enterprises in 12 batches of resin raw materials do not meet the GB9691-1988 "Hygienic Standard for polyethylene resin for food packaging", the qualified rate of resin material89.2%. Of which 5 batches of substandard residue on ignition, 7 batches of unqualifiedfor hexane extract. It is understood, residue on ignition and n-hexane index is unqualified, may lead to migration into food products in the presence of potentially hazardous materials in contact with food, food security.

What is the cause of some resin raw material sampling unqualified products, and all qualified situation?

The Bureau of quality supervision by experts analysis, a preliminary analysis of the reasons may be: one is to meet the processing and mechanical properties of the finished product requirements, enterprises in the production of tend to different grades ofpolyethylene resin raw material blending, a kind of nonconforming resin and other resinmolded product qualified, the performance is still meet the health standards; two is thetest conditions of resin raw material requirements higher than the molding test conditions.

According to the problems of special supervision and inspection, the Bureau will beinformed of relevant information of Shanghai city food safety supervision department,and requested the city districts and counties food related products production andsupervision departments to take further measures, crack down on illegal activities, to further strengthen the use of polyethylene resin raw material in the production of food related products enterprise supervision, and urge enterprises to implement the main responsibility.

Found in the security situation of instant noodles bowl when evaluating, wax technologyhas been widely used in the production of paper container, but because of the low melting point paraffin wax -- about 60 degrees Celsius, so the waxed paper containerused for containing low temperature food, such as ice cream, ice, ice cola, andtemperature to achieve instant noodles more than 90 degrees Celsius, so the waxed paper container was not used in the production of instant noodles bowl. In addition,instant noodles bowl has generally contain polystyrene (PS) foam material, but with thedevelopment and progress of the production technology, instant noodles bowl of PS foam material is polyethylene (PE) film lamination products replaced, in 68 batches ofpolyethylene (PE) film paper composite instant noodles bowl to carry out safetyassessment, explore in contrast to contain water and oil kind food conditions, heated to 100 degrees Celsius, whether there is a plasticizer, antioxidant, bisphenol A migration to the food or other substances. The evaluation results show that, the 68 batch of instant noodles bowl were not detected in the material migration.

At the same time, the Shanghai Municipal Quality Supervision Bureau of the city'scommercial production of electric heating food processing equipment, product quality supervision and spot checks carried out, a total of 15 batches of checks. Upon examination, 2 batches of substandard, Dinuote brand electric griddle production company was Shanghai tangliang hotel supplies Co. Ltd. Pudong and Shanghai GreenIndustrial Co., Ltd production Teppanyaki equipment. Failed projects involvingclassification, signs and instructions, input power and current, heating, non normal work,power connection and external flexible cords, protection against access to live parts,grounding measures etc..
