**In the Wave of Green Circular Economy, R-PET Materials Demonstrate Broad Application Prospects**

In the wave of green circular economy, R-PET (Recycled Polyethylene Terephthalate) materials, with their excellent performance and characteristics, show broad application prospects in fields such as textiles and packaging. Driven by high standardization and high value-added products, some high-end recycled PET products have even entered the realm of food-grade applications, setting a new benchmark for the industry.

Application of Photometric Sorting Technology in the R-PET Industry

 In recent years, with the enhancement of environmental awareness and the continuous advancement of recycling technology, photometric sorting technology has achieved remarkable results in the R-PET recycling field. Color sorting machines, as key tools in this field, are widely used in the sorting process of R-PET with different colors due to their efficient sorting capabilities. Meanwhile, plastic sorting machine also demonstrate the ability to identify and separate differences in R-PET materials to some extent.

However, faced with the increasingly higher quality demands from downstream users, the traditional "plastic color sorter > polymer sorter" combination method appears inadequate when tackling some complex challenges. The main issues exposed include:

1. **Difficulty in Distinguishing Very Light Color Differences**:

 In recent production lines, although plastic colour sorting machine can efficiently distinguish most color differences in R-PET, they struggle to accurately identify very light color differences, affecting the purity and reuse value of the recycled materials.

2. **Difficulty in Removing PET-G Low-Temperature Materials**:

As a low-temperature material, PET-G has physical characteristics similar to conventional PET, making it difficult for traditional material recognition technology to accurately remove it from recycled materials. This not only increases the difficulty of subsequent processing but also affects the quality of recycled products.

3. **Difficulty in Identifying Food-Contact Materials**:

During the recycling process, common food-contact materials such as PC, Tritan, and PPSU are often difficult for plastic color sorting and NIR plastic sorting to effectively identify due to their certain similarities in appearance and material with R-PET. The inclusion of these materials poses a serious quality threat to recycled products.

**Technological Breakthroughs Elevate R-PET Purity to New Heights**

Among the company’s numerous innovative achievements, the GVR Pro series models, equipped with very light color recognition technology, are specially developed to address the issue of identifying minor color differences in R-PET materials. They can accurately identify minor color differences in R-PET materials, improving the accuracy and efficiency of color sorter. Meanwhile, our R&D team continuously optimizes algorithms and upgrades hardware to achieve high-precision identification of minor differences in high-end materials such as PC, Tritan, PPSU, and PET-G. The GIR Pro series models, custom-developed for the high-purity material needs of polyester plastics R-PET, not only have extremely high identification accuracy but are also easy to operate and highly stable. They are highly praised by users and are referred to as “zero PC models.”

**Striving for Ultimate Purity Together**

In the fiercely competitive market, the performance bottlenecks of outdated equipment and the collaboration concerns of traditional production lines gradually surface, becoming key factors restricting industry development. With a unique perspective, we have embarked on the path of "one factory, one custom" production line design. By customizing equipment and production line combinations, we fully maximize the overall process performance, providing users with an extremely pure sorting experience.
