Abstract

During the last decades, thermoplastic packaging market has rapidly grown thanks to the rapid increase of global consumption, globalization and the unbeatable compromise between properties and large availability of relatively cheap commodity polymers. Recent awareness of the urgency of dealing with environmental concerns has stimulated the R&D on green materials such as biobased and biodegradable polymers, in this case mainly for short-term packaging applications. Main advantages are a lower environmental impact and a controlled end of life by enzymatic degradation till mineralization to resolve the complex equation linked to the waste management. Thus, the aim of this review is to highlight the variety of existing biobased and biodegradable polymers and their corresponding multiphasic systems, in connection with their production, relative properties and applications for packaging.

摘要

在过去的几十年里，由于全球消费的快速增长、全球化以及在性能和相对便宜的商品聚合物的大量供应之间的无与伦比的折衷，热塑性包装市场迅速增长。最近对解决环境问题紧迫性的认识刺激了对绿色材料的研发，例如生物基和可生物降解聚合物，在这种情况下主要用于短期包装应用。主要优点是较低的环境影响和通过酶降解直到矿化来解决与废物管理相关的复杂方程的受控寿命结束。因此，本综述的目的是突出现有的生物基和可生物降解聚合物的种类及其相应的多相系统，以及它们的生产，
