Along the edge of the cardboard box, a crease was made by hand and the box board broke with a sound. After peeling off the outermost layer of the cardboard box, it was found that the originally hollow honeycomb paper wall was filled with gray-white cement slurry. If calculated according to the price of 3.5 yuan per catty for apples, it means that consumers would have to pay about 10 yuan extra just for a cement-filled cardboard box.
In Qingyuan, Mr. Wen, a local resident, reported that he was shocked to find cement slurry in the packaging box of a box of apples he bought from a fruit wholesale market.
