““Printed plastic bags” should not be reused
Thread Content
In daily life, it is common for housewives to reuse plastic bags. However, experts point out that attention should be paid to the adverse effects on the human body of reusing plastic food packaging bags, especially those with printed text. Wang Yi, director of the Dietetic Nutrition Department at Guang’anmen Hospital, said that plastic bags with printed words or patterns contain a certain amount of lead. Many people like to reuse plastic bags or store food in them for long periods of time, which allows the food to come into direct contact with the lead-containing printed text. She explained that the use of weak acids such as vinegar can remove 0.1 milligrams of lead from lead-printed packaging covering an area the size of a bread slice – an amount equal to twice the daily intake of lead for humans. While this level of lead does not pose a significant threat to health, it can still have potential adverse effects on the body. It is best not to use plastic bags with patterns or printed words to store food, and certainly not to reuse them.
You can’t generalize about everything. To determine whether it can be reused, one must distinguish it from printed materials. It is difficult to distinguish in ordinary consumption whether it is printed with lead type. Are there any restrictions on lead content in printing materials in food packaging safety regulations? There must be relevant regulations. It is truly unethical for businesses to use lead-containing packaging; such practices should be eliminated at the source.
Additionally, the original poster is confusing a concept. Containing 0.1mg of lead is a different concept from ingesting 0.1mg of lead. Not all of the lead from printing materials transfers to food. Of course, out of the poster’s kindness, one should indeed pay attention to food safety issues.
Is the poster the one who produces plastic bags, always eager to increase consumption?
