Over 40 percent of companies that manufacture disposable lunch boxes for Beijing markets are supplying low quality and possibly dangerous products, reveals survey.
Dong Jinshi, executive vice-president of the International Food Packaging Association, said at a press conference that out of 17 disposable box manufacturers they had probed, only 10 were producing quality products.
One of the 17 producers was found to still be selling foam lunch boxes, which have been banned since 2001 as they release toxic substances.
Dong said the association reported its findings to the Beijing Bureau of Quality and Technical supervision. The bureau quickly took action and closed the factory making the foam lunch boxes.
According to the China Daily, the association revealed nearly 15 billion disposable lunch boxes are used throughout the nation and over 90 percent are made of plastic.
Some makers preferred using cheap toxic materials, including industrial calcium carbonate, in an attempt to keep down production costs.
The association also announced that another of its investigations, which revealed that napkins sold in some areas are of low quality. Some of the napkins, which were recycled from waste paper, were found to be extensively bleached with brightener.
"Among some 40,000 restaurants in Beijing, I believe more than half of them are using the substandard napkins," said Dong.
Dong has suggested customers not to buy low quality products from open markets, and has urged them to buy quality products with trademarks from superstores.
