Import Calcium Carbonate Masterbatch — Buy in Bulk from Supplier in China

Greenplas Co., Ltd’s Calcium Carbonate Masterbatch is engineered for PE, PO, and PP plastic bags and films, offering enhanced strength and durability in extrusion and blowing processes. The masterbatch incorporates a high calcium carbonate loading to reduce resin usage while maintaining performance in thin-film applications. Based in Shenzhen, China, this product is optimized for manufacturers in the packaging and consumer goods sectors.

The material’s calcium carbonate is typically ground to a fine 2-10 micron range, ensuring smooth processing and a matte finish in films. It is compatible with a broad range of polyolefin resins and can include processing aids such as lubricants or anti-blocking agents to improve line speeds. Standard industry practice often includes a coupling agent to bond the filler with the polymer matrix, enhancing mechanical properties.

Common applications include shopping bags, agricultural films, and industrial packaging where cost efficiency and stiffness are critical. Buyers in the plastics industry use this masterbatch to lower material costs without compromising tensile strength or puncture resistance. Trade terms such as FOB Shenzhen are typical, with packaging suited for containerized shipments. Lead times and MOQs should be confirmed directly with Greenplas Co., Ltd.
