According to the risk monitoring, the main quality and safety risk of degradable plastic bags is that the relative biodecomposition rate index does not meet the requirements of the national standard, and its hazards mainly include:
It affects the growth of crops. Waste plastic products whose relative biodecomposition rate does not meet the standard requirements accumulate continuously in the soil, which will affect the absorption of nutrients and water by crops, resulting in crop yield reduction, and affect the sustainable use of land. The plastic household waste mixed with the relative biological decomposition rate does not meet the standard requirements is not suitable for composting, and the waste plastic should be sorted out from the garbage, increasing the cost of composting.
Pose a threat to the survival of animals. Waste plastic products that are discarded by people at random and whose relative biological decomposition rate does not meet the standard requirements are swallowed by animals as food. As the consumed plastic stays in the stomach for a long time and is difficult to digest, it is easy to lead to animal poisoning or death.
High temperatures break down toxic substances. Plastic products are not toxic substances, but recycled plastic products due to the recycling equipment is not perfect, simple technology, relative biological decomposition rate and other indicators do not meet the national standard requirements, recycled plastic products at 65℃ when the temperature will precipitate toxic substances, if used in food-related products into food, easy to cause harm to human health.
In view of the above situation,Market Supervision Bureau tips:
When purchasing degradable plastic bags or other degradable products, check whether the product label has the degradable JJ logo and whether the material description of the product is degradable plastics such as PLA, PBAT, PBS.
