“限塑令”背景下可降解塑料吸管产品质量状况研究

Product Quality of Degradable Plastic Straw in the Context of“Plastic Limitation”

“限塑令”背景下可降解吸管需求旺盛,了解其产品质量状况尤为重要。本文浅析了当前降解吸管发展状况和相关标准,从流通领域和电商平台采集了10组降解吸管,进行了生物降解试验,发现2组不合格产品,通过热重和红外光谱分析,确定不合格样品是以聚丙烯为主要原料的吸管。针对降解吸管提出了监管和使用的建议。

In the context of“limiting the use of plastic products”,the demand for degradable straw is strong,so it is important to understand its product quality.This paper briefly analyzes the current development status and related standards for degradation straws.Ten groups of degradation straws were collected from the circulation field and e-commerce platform,and the biodegradation test was carried out.Two groups of unqualified products were found.Through TG and infrared spectrum analysis,it was determined that the unqualified sample was a straw with polypropylene as the main raw material.Suggestions on the supervision and use of degradation straws were put forward in the paper.
