在20世纪70年代，一个生产塑料购物袋的商业系统开始运作，第一个由轻质高密度聚乙烯（HDPE）薄膜制成的购物塑料袋被引入超市行业，作为纸袋的替代品。塑料袋变得非常受消费者和零售商的欢迎，因为它们是一种卫生、轻便和坚固的包装形式。另一方面，塑料袋已经成为对环境的真正危害，因为它们在很长一段时间内不会在垃圾填埋场被分解，更重要的是，如果留在环境中并被冲入大海，它们会被海洋生物误以为它们是食物而吞下。近年来，许多国家的政府开始与工业工程师和环保主义者合作，减少塑料袋对环境的影响。要问的问题是，塑料袋是否真的对环境有害，回收利用是废弃塑料袋的唯一解决方案吗？在这篇文章中，作者试图分析塑料袋的历史，看看为什么塑料袋会成为一个问题，以及未来可能的解决方案是什么。
In the 1970s, a commercial system for manufacturing plastic grocery bags became operational and the first grocery plastic bag, made of light High-Density Polyethylene (HDPE) film, was introduced to the supermarket industry as an alternative to paper sacks. Plastic bags became very popular with consumers and retailers, as they are a hygienic, lightweight and strong form of packaging. On the other hand, plastic bags have become a real hazard to the environment because they do not break down in landfills for a very long time and, even more critical, if left in the environment and washed down to the sea, they are swallowed by marine life that mistake them for food. In recent years, governments in many countries have started to work with industrial engineers and environmentalists to reduce the environmental impact of plastic bags. The question to ask is whether plastic bags really represent an environmental hazard and is recycling the only solution for waste plastic bags? In this article, the authors endeavour to analyse the history of plastic bags by looking at why they have become a problem and what potential future solutions are.
