Yesterday, the International Food Packaging Association Secretary Dong Jinshi told this reporter that the phenomenon of plastic containers over the use of the more common, which will undoubtedly increase the number of carcinogens in plastic products "run "" and the risk of accumulation in the human body.

Plastic containers also have shelf life

It is understood that in March this year, the Hong Kong Consumer Council released an investigation report that nearly 30% of microwaveable plastic lunch boxes will release plasticizers.

“We have found that the longer the plastic containers are used, the greater the risk of “toxicity”.” Dong Jinshi said that this also means that plastic container products have a shelf life, and they will age when they expire. In addition, PET bottles have previously been exposed to carcinogens containing heavy metals, and PET is currently the most used package in beverages.

"Even if the product is up to standard, it will increase the potential risk to the human body over the extended period of use," said Dong Jinshi.

Plastic cup with a few years of common

Yesterday, the reporter interviewed more than 20 people randomly. None of the citizens could say the shelf life of plastic container products. In the survey, common food-grade plastic products were common in three or four years or even longer.

“Only heard that the production date has been marked and the shelf life has never been heard.” During the visit, some of the plastic products sales companies took a few products for the reporter to see. Whether it was a cup or a washbasin, there was no warranty period.

Afterwards, the reporter contacted the manufacturer according to the contact method on a plastic drinking cup. The staff member responded that at present, the country only requires labeling materials, uses, production dates, precautions, etc., and there is no warranty period.

In shopping malls such as supermarkets in the city, when a reporter consults for how long plastic products can be used, the answer given by most shopping guides is: “If you break it, you will change it. If you use it, you will continue to use it. We really don’t know if it can. How long does it take?"

Frequent use of the proposed two-year exchange

How long is the shelf life of a plastic product? Dong Jinshi said that the use of plastic products and cleaning methods are different, and they have a certain influence on the “lifespan” of plastic products. Although there is no clear definition of which plastic material quality deadline is, it is generally stated in the industry that Most plastic products have a shelf life of three to five years.

Dong Jinshi suggested that food-grade plastic products in daily life should preferably be changed every two years. After a period of use, it depends on whether they have changed color, become brittle, and there are no irregularities inside. If this is the case, it should be timely. replace.

“The packaging of plastic products, especially the packaging of plastic products for food, urgently needs to mark the warranty period.” Dong Jinshi stated that only in this way can the risk of plastic “toxicity” endangering health be reduced.
