Plastic bags or foam boxes used to store hot foods such as hot soy milk, corn water, soup, rice at 78-80oC will cause additives to soften, toughen, and toughen the plastic bags, causing side effects and easily contaminating the food with toxins.

Through the reporter's investigation, the plastic bag wholesalers at some large markets in Hanoi said that they sell about 30-40kg of bags every day, priced from 2,300 - 4,500 VND/tael. The traders said: Plastic bags for vegetables, meat... in the market are made from recycled plastic. Just by looking at them, you can tell which bags are good, which are bad, and even where they are produced.

Plastic bags or foam boxes to store hot foods such as hot soy milk, corn water, soup, rice... at 78-80oC or plastic wrap that melts after heating in a microwave oven will easily release DOP (dioctin phthalate) into food.

People who buy these plastic bags said that they usually get the bags in Hanoi such as: Trung Van, Tu Liem, La Phu, An Khanh, Hoai Duc, Hanoi and in neighboring provinces of Hanoi such as: Hung Yen, Nam Dinh, Hai Phong...

However, when asked about the quality of the bags, these business people said that they and many consumers do not care about the quality of the bags. This is a potential danger that destroys the health of consumers.

Heavy metal contamination with cadmium and lead due to the use of plastic bags

Associate Professor, Dr. Nguyen Duy Thinh - Former lecturer at the Institute of Biotechnology and Food Technology, Hanoi University of Science and Technology, said that currently, Vietnam is using mostly recycled plastic bags, causing many risks of lead and cadmium contamination for users.

There are two types of plastic bags: The first type is made from 100% virgin PV and PP plastic particles from pure petroleum. This type of plastic is not toxic to humans.

The second type (the type we are commonly using) is recycled plastic bags from many used plastic products. Among them, there are even paint cans, toilet bowl cleaner bottles... During the recycling process, handmade plastic will absorb heavy metals such as cadmium, lead... (substances that lead to cancer).

If eating food contaminated with DOP (dioctin phthalate) from melted plastic for a long time, boys may become feminized and infertile, while girls are at risk of early puberty.

According to Associate Professor Thinh, the process of toxic contamination from plastic bags occurs more strongly when exposed to high heat. Plastic bags or foam boxes used to store hot foods such as hot soy milk, corn water, soup, rice at 78-80oC will cause additives to soften, toughen, and toughen the plastic bags, causing side effects and easily leaching toxic substances into food.

One of these substances is DOP (dioctin phthalate), which is similar to female hormones, so it is very harmful to men and children whose reproductive organs are not yet fully developed. If exposed to this substance for a long time, boys may become feminized and become infertile, while girls are at risk of early puberty.

Associate Professor Thinh especially noted that plastic wrap should never be used on the surface of food to be heated in the microwave. After being heated in the microwave to 300-500oC, these plastic wraps will melt and the plastic will stick to the food.

Never use plastic wrap on the surface of food to heat it in the microwave. After being heated in the microwave to 300 - 500oC, these plastic wraps melt and the plastic will stick to the food.

Therefore, to use plastic bags safely, people should choose colorless bags with high transparency, gloss, bright colors, and product surfaces that are not rough or scratched. Limit the use of plastic to store hot, sour, spicy foods...

Associate Professor Nguyen Duy Thinh said: Currently, scientists around the world and in Vietnam are researching to create plastic bags that are a mixture of 60% regular plastic and 30% starch (usually wheat flour). This type of bag will only take 3-5 years to decompose, not up to 500 years like the recycled plastic bags currently used. It is expected that this product will cost more than plastic bags and will be widely used in the future.
