Han King : Review K-2022 - Post Consumer Recycling For Environmental Resource Circulation

At K-2019, the plastic industry was focused on downgauging thickness to reduce the raw materials used in production, to save resources. The material suppliers developed high-performance resin formulation for the end-product to achieve downgauging with better properties. There were two hot topics – recycling and biodegradation. The plastic product, made from biodegradable materials, can degrade naturally by burying the plastic wastes. However, with changes in temperature, moisture and oxygen, it will affect the degradation process and delay efforts to improve the environment.

The topic of recycling grew hotter at K-2022. Emphasis was placed on using post-consumer recycled resins back into the production process to achieve environmental policies, implemented by governmental bodies. Such policies call for a definite ratio of post-consumer recycled resins to prime resins, as well as the frequency of recycling post-consumer waste. However, the post-consumer recycled resins do affect the properties of the blown film and its production stability. Therefore, it is important to manage the quality for post-consumer recycled resins.
