Nowadays, for HDPE shopping bags, T-shirt bags & food packaging bags, it’s very popular to blend recycled material & calcium carbonate (CACO3). Especially CACO3, it can cut down your resin cost, increase capacity & make your film products heavier. Although CACO3 provides so many advantages, it changes the feature of HDPE film. HDPE film will be reduced in tensile strength after blending CACO3, so that HDPE film won’t pack heavy subjects. Besides, CACO3 will make HDPE film feels dusty.

High Density Polyethylene Resin, briefly, HDPE film grade resin mainly designed for producing shopping bags, T-shirt bags, grocery bags, garbage bags, food packaging and many so on.
