Yantai Hengchang Packaging Co., Ltd.

Specially designed for pre-mixing PP pellets and masterbatches in the FIBC production pre-processing stage. Mixer adopts a ribbon blade structure with rotary shear action to ensure homogeneous material blending and prevent layered accumulation. Adjustable mixing speed ensures high efficiency and low energy consumption. Constructed with stainless steel for abrasion/corrosion resistance and smooth discharge, enhancing pre-treatment uniformity as a critical equipment for optimizing raw material formulation. 

Designed specifically for FIBC (Flexible Intermediate Bulk Container) production, melting machine efficiently melts and blends PP granules, calcium carbonate masterbatch, and color masterbatch. The equipment heats and maintains a constant temperature during operation to ensure material melting, integrated with an intelligent temperature control system that provides uniform and stable thermal regulation for homogeneous composition. Featuring user-friendly operation and rapid heating, the equipment sustains stable melting temperatures for raw materials over extended periods, making it ideal for continuous production processes to boost throughput capacity.

As a critical forming equipment for FIBCs, Extrusion line extrudes molten raw materials into high-strength flat yarns. Equipped with a high-efficiency extrusion system, precision die, and multi-roller drafting unit, it achieves polymer plastication and orientation through precise temperature control and adjustable draw ratios. Cooling and cutting mechanisms ensure dimensional stability, smooth surface finish, and compliance with tensile strength standards. High automation guarantees premium-quality raw yarns for downstream processes.

Used for post-extrusion yarn alignment, consolidating multiple flat yarns into uniform strands to supply stable feedstock for circular weaving. Features multi-roller yarn guides and tension equalization systems, with adjustable dividers for alignment correction and precise tension/spacing control. VFD motors synchronize with extrusion line speeds to ensure process synchronization. Open-frame design facilitates cleaning and enhances strand regularity, serving as a pivotal interface unit.

Core FIBC forming equipment that weaves cabling strands into tubular base fabric. Utilizes multi-shuttle circular weaving technology with VFD motors and precision gearboxes for high-speed operation. Real-time tension monitoring and modular frames enable rapid mold changes to accommodate grammage specifications. Produces high-strength base fabric for subsequent processing stages.

The automatic printing system consists of unwinding, printing, drying, and rewinding units. The unwinding unit steadily feeds woven bags, while the printing unit employs advanced technology to accurately reproduce vibrant patterns and text with high clarity. After printing, the drying unit rapidly cures the ink. The rewinding mechanism neatly rolls the finished products. Integrated with an intelligent control system, the equipment offers user-friendly operation, significantly enhancing printing efficiency and quality.
