摘要
塑料垃圾已经成为全球环境污染的罪魁祸首之一,而废旧塑料包装材料是塑料垃圾的主要来源。塑料包装材料作为一种最常见的包装材料,具有质轻、防水、耐用、生产技术成熟、成本低的优点,在全世界被广泛应用且使用量呈逐年增长趋势。废旧塑料包装进入环境后,由于很难降解,会造成长期的、深层次的生态环境问题。如何减少甚至规避废旧塑料包装材料对环境造成污染,是全球塑料产业工作者和科学家们积极探索、研究的热门课题,目前在行业内比较成熟的有降解塑料、单一材质易回收包装材料和塑料热分解三个研究和发展方向。
Plastic waste has become one of the main culprits of global environmental pollution,and waste plastic packaging materials are also the main source of plastic waste.As one of the most common packaging materials,plastic packaging materials have the advantages of light weight,waterproof,durable,mature production technology and low cost.They are widely used all over the world and are growing year by year.However,after the waste plastic packaging enters the environment,it is difficult to degrade,which will cause long-term,deep-seated ecological and environmental problems.How to reduce or even avoid the environmental pollution caused by waste plastic packaging materials is a hot topic actively explored and studied by global plastic industry workers and scientists.At present,there are three mature research and development directions in the industry:degradable plastics,single material recyclable packaging materials and plastic thermal decomposition.
