避免购买劣质塑料袋,使用风险大
可降解塑料袋作为普通塑料购物袋的替代品,在改善环境方面发挥着积极作用,但如果可降解塑料袋产品不能达到标准要求,也会对环境造成影响。
As a substitute for ordinary plastic shopping bags, degradable plastic bags play a positive role in improving the environment. However, if degradable plastic bag products do not meet national standards, it will also have an impact on the environment.
济南塑料袋是以生物降解塑料树脂为主要原料生产的薄膜、经热合或黏合等制袋工艺加工制得的塑料购物袋。生物降解塑料袋按照材质分主要包括:聚乳酸+聚己二酸/对苯二甲酸丁二酯共混物(PLA+PBAT)、聚乳酸+聚己二酸/对苯二甲酸丁二酯+淀粉共混物(PLA+PBAT+St)、聚乳酸+聚己二酸/对苯二甲酸丁二酯+碳酸钙共混物(PLA+PBAT-CaCO3)等。生活中常见的生物降解塑料购物袋还分为食品接触用和非食品接触用。
Jinan plastic bags are plastic shopping bags produced from biodegradable plastic resin as the main raw material, and processed through bag making processes such as heat bonding or bonding. Biodegradable plastic bags mainly include: polylactic acid+polyadipic acid/butylene terephthalate blend (PLA+PBAT), polylactic acid+polyadipic acid/butylene terephthalate+starch blend (PLA+PBAT+St), polylactic acid+polyadipic acid/butylene terephthalate+calcium carbonate blend (PLA+PBAT CaCO3), etc. The commonly used biodegradable plastic shopping bags in daily life are also divided into food contact and non food contact.
劣质的可降解塑料袋存在的质量风险主要是相对生物分解率指标达不到标准要求,其危害主要有:
The quality and safety risks of inferior degradable plastic bags mainly lie in the fact that the relative biodegradation rate index does not meet the national standard requirements, and their hazards mainly include:
影响农作物生长。相对生物分解率不符合标准要求的废塑料制品混在土壤中不断累积,会影响农作物吸收养分和水分,导致农作物减产,影响土地的可持续利用。混有相对生物分解率不符合标准要求的塑料生活垃圾不适用于堆肥,要从垃圾中分拣出来废塑料,增加堆肥成本。
Affects crop growth. The continuous accumulation of waste plastic products with a relative biodegradation rate that does not meet the standard requirements in the soil can affect the absorption of nutrients and water by crops, leading to crop yield reduction and affecting the sustainable use of land. Domestic waste mixed with plastic whose relative biodegradation rate does not meet the standard requirements is not suitable for composting. Waste plastic needs to be sorted out from the waste, increasing the cost of composting.
对动物生存构成威胁。人们随意丢弃的相对生物分解率不符合标准要求的废塑料制品,被动物当作食物吞入,由于吃下的塑料长时间滞留胃中难以消化,易导致动物中毒或死亡。
Posing a threat to the survival of animals. Waste plastic products with a relative biodegradation rate that does not meet the standard requirements that people casually discard are swallowed by animals as food. Due to the prolonged retention of plastic in the stomach, it is difficult to digest, which can easily lead to animal poisoning or death.
高温环境会分解出毒害物质。塑料制品本害物质,但再生塑料制品因回收再利用的设备不够完善、工艺简陋,相对生物分解率等指标达不到标准要求,再生塑料制品在温度达到65℃时会析出毒害物质,若被用于食品相关产品渗入到食品中,易对人体健康等造成危害。
High temperature environments can decompose toxic substances. Plastic products are originally free of toxic substances, but recycled plastic products do not meet the national standard requirements due to inadequate recycling equipment, simple processes, and relative biodegradation rates. Recycled plastic products will release toxic substances when the temperature reaches 65 ℃. If used in food related products, they can seep into food, easily causing harm to human health and other aspects.
So when purchasing, it is important to pay attention to product quality and safety, and remind consumers to consume cautiously and use safely. For more related content, come to our website http://www.jingmeisuliao.com consulting service
