Preparation and application of a polyethylene foam packaging material
AI summary Read the abstract
This review examines the preparation, modification, and application of polyethylene foam as a packaging material, discussing its lightweight, insulating, and shock-absorbing properties alongside the environmental and recycling challenges its widespread use creates. The authors propose approaches to address sustainability concerns while maintaining the performance characteristics that make polyethylene foam central to the modern packaging industry.
With the development of science and technology, packaging materials play an important role in the safety, hygiene and transportation of goods. Polyethylene foam has become the core component of the modern packaging industry because of its lightweight, sound insulation, heat insulation, shock absorption and other characteristics. However, its production and use also bring environmental protection and recycling problems. In this paper, the preparation, modification and application of polyethylene foam will be discussed in depth, aiming to provide ideas and suggestions for solving problems. It is hoped that the research will lead to the development of a more environmentally friendly and sustainable packaging material, which will contribute to the sustainable development of mankind.
