With the growing global emphasis on environmental protection and the sustainable utilization of resources, the recovery technology of food-contact recycled polyethylene terephthalate (PET) materials has drawn significant attention. The recovery technology, the regulation and the development trends of food-contact recycled PET materials were reviewed. Through a detailed analysis of different recycling methods, the significance of technological advancements in enhancing recycling efficiency and product quality is highlighted. Simultaneously, in combination with regulatory experiences from various countries, suggestions for improving the regulatory system of food-contact recycled PET in China were proposed, with the aim of facilitating the healthy and sustainable development of the food-contact recycled PET industry.

SUSTAINPELLET Low-Shrinkage Polypropylene: Redefining the Future of Sustainable Food Packaging ——Innovative Material Technology for Safety and Environmental Stewardship

The Global Recycled Standard (GRS), established by Textile Exchange, is an international certification system verifying the proportion of recycled materials in products and environmental compliance in production. Since its launch in 2008, GRS has expanded from textiles to plastics, packaging, electronics, and more.

Since the outbreak of CHINA-US trade friction in 2018, both countries have imposed additional tariffs on thousands of goods, including plastic products. By April 2025, cumulative US tariffs on certain Chinese goods had reached 104%, significantly increasing export costs for Chinese manufacturing. Polypropylene (PP), a critical material in the home appliance industry (accounting for over 40% of plastic usage in appliances), urgently requires technological innovation to reduce costs and improve efficiency. This article proposes systematic solutions for PP materials based on foaming theory, filling systems, structural optimization, and recycled material applications, using refrigerator and washing machine components as case studies and integrating domestic and international research with industrial practices.

In recent years, the application of recycled PC/ABS alloy materials in the automobile industry has witnessed an explosive growth. Behind this trend are multiple breakthroughs in material modification technology, which not only solve the pain point of the performance decay of recycled plastic, but also meet the dual needs of automobile lightweight and environmental protection.

As a pioneer in global environmental policy, the EU systematically promotes the application of recycled plastics through a number of regulations. For example, the proportion of recycled materials in PET bottles should reach 25% by 2025, increase to 30% by 2030, and further extend to areas such as automotive manufacturing, requiring the use of 25% of recycled materials. In addition, the EU revision to the Packaging and Packaging Waste Regulation clearly states that the minimum proportion of recycled plastics in all types of packaging by 2030, such as PET contact sensitive packaging, should contain 30% recycled materials. These policies not only cover the packaging field, but also force enterprises to transform through the binding force of the whole industrial chain.

As an innovation leader in environmentally friendly recycled materials, Sustain Pellet (STP) New Materials is committed to providing customers with high-quality, customized recycled materials solutions. With advanced physical recycling and modification technology as the core, we transform recycled plastics, glass and other wastes into high-performance recycled materials, which are widely used in automotive, electronics, home furnishing, packaging and other fields. By strictly following international standards (such as US FDA NOL, EU EFSA, GRS), we ensure that every gram of material is safe, environmentally friendly and traceable to help customers achieve sustainable development goals. Choosing STP is not only to choose high-quality materials, but also to choose the responsibility and commitment to the future.
