Several factors that hinder the development of environmentally friendly materials
Although there are many studies and reports on degradable plastics, there are still many specific issues, including : 1 The strength of degradable plastics is low, which can not meet the strength requirements of flexible packaging. 2 The barrier properties of degradable plastics can not meet the requirements of flexible packaging products ; 3 Degradable plastics have short shelf life and poor performance stability ; 4 The price is high. In general, the implementation of the plastic restriction order has promoted the application of degradable materials, but the road of sustainable development is currently in its infancy, and there are still many imperfections that need to be actively developed and improved by enterprises. 'Safety, health and environmental protection ' is the future development direction of packaging materials. Packaging is evolving into a force for change, from visual art, protecting consumer safety, sustainability needs and other aspects are constantly improving.
