避免購買劣質塑料袋,使用風險大

可降解塑料袋作為普通塑料購物袋的替代品,在改善環(huán)境方面發(fā)揮著積極作用,但如果可降解塑料袋產品不能達到標準要求,也會對環(huán)境造成影響。
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.
濟南塑料袋是以生物降解塑料樹脂為主要原料生產的薄膜、經熱合或黏合等制袋工藝加工制得的塑料購物袋。生物降解塑料袋按照材質分主要包括:聚乳酸+聚己二酸/對苯二甲酸丁二酯共混物(PLA+PBAT)、聚乳酸+聚己二酸/對苯二甲酸丁二酯+淀粉共混物(PLA+PBAT+St)、聚乳酸+聚己二酸/對苯二甲酸丁二酯+碳酸鈣共混物(PLA+PBAT-CaCO3)等。生活中常見的生物降解塑料購物袋還分為食品接觸用和非食品接觸用。
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.
劣質的可降解塑料袋存在的質量風險主要是相對生物分解率指標達不到標準要求,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:
濟南塑料袋
影響農作物生長。相對生物分解率不符合標準要求的廢塑料制品混在土壤中不斷累積,會影響農作物吸收養(yǎng)分和水分,導致農作物減產,影響土地的可持續(xù)利用。混有相對生物分解率不符合標準要求的塑料生活垃圾不適用于堆肥,要從垃圾中分揀出來廢塑料,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.
對動物生存構成威脅。人們隨意丟棄的相對生物分解率不符合標準要求的廢塑料制品,被動物當作食物吞入,由于吃下的塑料長時間滯留胃中難以消化,易導致動物中毒或死亡。
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.
高溫環(huán)境會分解出毒害物質。塑料制品本害物質,但再生塑料制品因回收再利用的設備不夠完善、工藝簡陋,相對生物分解率等指標達不到標準要求,再生塑料制品在溫度達到65℃時會析出毒害物質,若被用于食品相關產品滲入到食品中,易對人體健康等造成危害。
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.
