Calcium carbonate filler

Greenplas (shenzen) Co.Ltd supplies calcium carbonate filler designed for polyethylene, polypropylene and polyolefin plastic bags. The filler is also listed as suitable for blowing moulds, fruit‑case or turner‑box production, injection moulding, sheet extrusion and thermosetting applications. For film formulations the supplier recommends a loading level of 20 % to 30 %, while injection mould blends may contain 20 % to 70 % of the filler. The product is described as giving a smooth feel, being harmless, non‑toxic and capable of replacing a portion of petroleum‑based resin.

In the wider market calcium carbonate fillers commonly meet ASTM D 5630 with a CaCO₃ content of 80 % ± 1 %. Typical particle size distributions lie between 1 µm and 5 µm, with a bulk density around 1.1 g / cm³. Standard melt flow rates for comparable masterbatches are about 0.05 g / 10 min measured at 190 °C under a 2.16 kg load. Moisture content is usually kept below 0.1 % to avoid processing issues.

The filler is primarily purchased by manufacturers of flexible packaging films, injection‑moulded components and rigid plastic containers. Buyers typically seek to improve opacity, increase stiffness and reduce material cost while maintaining processing stability. Greenplas does not publish minimum order quantities, pricing or lead times, so importers should request these details directly. Because the supplier’s response rate is recorded as zero, confirming communication channels before placing an order is advisable.
