What Are HDPE Blow Grade Regrinds and Flakes?

HDPE blow-grade regrinds and flakes are recycled from post-consumer or industrial HDPE. "Regrinds" are shredded or ground plastic, whereas "flakes" are flat recycled fragments. These materials preserve HDPE blow grade resin characteristics, making them perfect for reprocessing into new products without compromising quality. Regrinds and flakes are sorted, cleaned, and treated to satisfy reuse specifications. To balance cost and performance, manufacturers combine these materials with virgin HDPE.
Manufacturing Process of HDPE Blow Grade Regrinds The production of HDPE blow grade regrinds and flakes involves several critical steps:
1. Collection and Sorting: Waste HDPE products are collected and sorted based on resin type, color, and cleanliness.
2. Cleaning: Advanced washing systems remove contaminants like labels, adhesives, and residue.
3. Shredding: HDPE waste is shredded into smaller pieces, forming regrinds. 4. Flaking: Shredded materials are further processed into flakes, ensuring consistent size and shape.
5. Quality Control: The regrinds and flakes are tested for purity, density, and melt flow index to ensure they meet the required specifications. By following this meticulous process, manufacturers can produce high-quality HDPE blow grade regrinds and flakes suitable for diverse applications.
