Many buyers confuse natural white rHDPE pellets with milky white rHDPE pellets.
They differ in raw source, appearance, and real-world performance.

Natural white rHDPE pellets show bright pure white tone, made from clean transparent HDPE containers. It has ultra-low impurities, high gloss, and a stable melt index. It is mostly used for high-end transparent packaging, cosmetic bottles, and clear plastic products.

Milky white rHDPE pellets present soft opaque milk white shade, mainly recycled from milk bottles and daily food HDPE vessels. It has good toughness and excellent blow molding properties. It is ideal for food storage bottles and household containers. It also works well for everyday plastic goods.

Both types of rHDPE pellets from Swanpoly are deeply sorted, washed and processed. All products pass GRS certification and comply with FDA food contact requirements. Compared with common recycled pellets, they have fewer black spots, less moisture and steady batch quality.

As professional China PCR polymer manufacturer, Swanpoly provides two grades of rHDPE pellets in bulk quantity. Customers can choose the right materials based on color needs, the production process, and budget. This helps support eco-friendly and cost-effective production.
