Are you still struggling to choose packaging materials? We'll explore the pros and cons of PET (polyethylene terephthalate) and PVC (polyvinyl chloride), two popular plastic packaging materials, to help you choose the one that best suits your packaging needs!

In order to implement the Sunnylands Statement on Strengthening Cooperation to Address the Climate Crisis, on October 31, 2024, the Circular Economy Task Force of the China-Us Climate Action Working Group held a briefing of the China-Us Circular Economy Expert Dialogue via video conference.Mr. Dechun Liu, Director General of the Department of Environmental Information of the National Development and Reform Commission, and Mr. Rick Duke, Deputy Special Envoy of the US President for Climate Issues, attended and addressed the meeting. Mr. Mark Kasman, Director of the Office of International Affairs of the US Environmental Protection Agency, chaired the meeting.

In April 2022, six departments including the Ministry of Industry and Information Technology issued the "Guiding Opinions on the 14th Five-Year Plan to Promote the High-quality Development of the Petrochemical and Chemical Industry" to optimize and integrate the research and development platform and create innovation centers in fields including high-performance engineering plastics. In December 2023, The State Council issued the "Action Plan for Continuous Improvement of Air Quality" notice, proposing to promote the low-nitrogen combustion transformation of gas PEEK materials.

Since the 1980s, PET as an engineering plastic has made breakthrough progress, and continued to develop nucleating agents and crystallization promoters, PET and PBT together as thermoplastic polyester, become one of the five major engineering plastics (PA PC POM PBT PPO).

PET plastic is the abbreviation for Polyethylene terephthalate in English, abbreviated as PET. As a small variety in the plastic classification, what are its properties? What are the application areas?

In September 2024, the price index of recycled plastic pellets in China was 759.6 points, a year-on-year decrease of 1.9% and a month on month decrease of 1.2%.

The rapid development of technologies such as 5G communication, the Internet of Things, artificial intelligence (AI), low altitude economy, 3D printing, and the rise of intelligent living and new energy vehicles will constantly increase the market's requirements for material performance, which will promote the innovation and development of the modified plastics industry.

Among many packaging materials, plastic packaging accounts for the highest proportion. It is worth noting that abandoned plastic packaging will weather and decompose into fine particles, which may eventually enter the human body through various forms. But plastic packaging is essential for goods, in the case that it can not be replaced, how to eliminate its harm? This paper proposes a third approach: the use of high-performance materials.

According to the statistics from 1949 to 2018, the recycling and reuse rate of waste plastics in China is only 30%, about half of the waste plastics are incinerated or buried with domestic waste, and the remaining 20% or so enter the natural environment without any treatment. It can be seen that the treatment status of waste plastics in China is very serious and needs to be improved.
