For the sustainable development of plastic packaging, it can be described as the industry's most concerned content, it determines the future development of the company and the focus of product development. Regarding the handling of plastic packaging after use, two approaches that are more recyclable and degradable are currently recognized. Recyclable has encountered the problem of being unable to recycle after laminating a variety of different material films. Now the industry's solutions have basically developed to "single materialization". For example, Dow, Borouge, and Jiangmen Hualong have developed PE films that can replace BOPA. The membrane substrate is fully PE for easy recycling. Degradability encountered two major problems: barrier properties when used in packaging, and the timeliness of degradation and microplastics. For example, a study of the degradation of plastic bags by the International Marine Litter Research Group of the University of Plymouth found that a biodegradable plastic bag placed in the marine environment for three years can still hold about 2.3 kg of articles. Therefore, some people believe that: a durable and repeatable Used plastic
Can degradable packaging solve the environmental problems of plastics?
