Import Blowing Film Filler Masterbatch — Buy in wholesale FOB from Supplier in Viet Nam

PE filler masterbatch for blowing film applications is a calcium carbonate concentrate dispersed in polyethylene carrier resin, designed to reduce raw material costs and modify film properties in extrusion processes. Gcc Minerals Jsc supplies this product from their location in Hanoi, Viet Nam, for compatibility with low-density and linear low-density polyethylene film extrusion. The masterbatch typically contains calcium carbonate at loadings of 70 to 80 per cent by weight, with the balance comprising carrier resin and processing aids to ensure uniform dispersion in the base polymer. Particle size distribution of the calcium carbonate filler, median diameter (d50), and top cut (d98) are critical parameters that determine film surface quality and mechanical properties.

The calcium carbonate used in blowing film masterbatch is typically surface-treated with stearic acid or calcium stearate to improve hydrophobicity and compatibility with non-polar polyethylene matrices. This surface modification reduces moisture absorption during storage, improves dispersion during extrusion, and minimises die build-up during continuous production runs. Typical melt flow index (MFI) of the masterbatch ranges from 2 to 10 g/10min at 190 degrees Celsius and 2.16 kg load, depending on the carrier resin grade and filler loading. The product finds application in polyethylene bags, garbage bags, T-shirt bags, roll bags, shopping bags, agricultural film, and biodegradable bag formulations where cost reduction and specific mechanical properties are required.

Gcc Minerals Jsc indicates compatibility with HDPE extrusion pipe and bar applications in addition to film and injection moulding, suggesting a versatile product range. Buyers should confirm with the supplier the exact calcium carbonate grade, whether it is coated or uncoated, the specific carrier resin density, and recommended let-down ratios for different film thicknesses and applications. The exact MOQ, packaging format, lead time, and available Incoterms are not stated in the listing and require direct confirmation. The supplier's trust tier is harbour with zero per cent displayed response rate, so proactive communication through multiple channels is advisable to establish trading terms and request technical data sheets.

Gcc Minerals Jsc is located at Xuan Phuong, Nam Tu Liem District, Hanoi City, 100000, Viet Nam, operating from the capital region with access to northern Viet Nam's industrial infrastructure and logistics corridors. The company holds a harbour trust tier designation with a response rate of 0.00 per cent and zero average response hours recorded on the platform, indicating limited or no recent engagement through platform-mediated communication channels. Their product focus spans calcium carbonate filler masterbatch for multiple polyethylene processing applications including blowing film, blow moulding, injection moulding, and HDPE pipe extrusion.

The supplier's name, Gcc Minerals Jscentials Jsc, suggests mineral processing or compounding as their core business, though the listing provides no information about manufacturing facilities, production capacity, quality certifications, or years of operation. No details are given about their calcium carbonate source, whether mined domestically in Viet Nam or imported, nor about their compounding equipment capabilities such as twin-screw extrusion or high-intensity mixing. Buyers should verify directly with Gcc Minerals Jsc their actual manufacturing status versus trading role, their quality control procedures including sieve analysis and melt testing, and whether they hold ISO 9001 or food-contact compliance certifications relevant to specific end-use applications.
