Hengchang Packaging's FIBC Production Equipment & Bulk Bag Manufacturing Machinery

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.

Designed for precision length cutting of tubular fabric, converting circular-woven base fabric into FIBC blanks. Employs high-speed rotary blades or thermal cutting systems with high-precision positioning for rapid and accurate cuts. Intelligent thermal control melts the cutting edges to prevent yarn fraying. Adjustable length/quantity settings and automated winding at the discharge end ensure efficiency. Durable construction simplifies maintenance.  

Advanced post-processing equipment specialized in integrated stitching of spout fabric and drawstrings. Automates spout folding, drawstring insertion, and cylindrical spout formation with uniform stitching. Equipped with intelligent feeding platforms and closed-loop tension control for automated feeding and stacking, driving revolutionary efficiency improvements. 

Designed for coating PE film onto base fabric. Utilizing a coating process, precise roller pressing and intelligent temperature control devices achieve uniform adhesion of the PE film. Equipped with automatic edge alignment and tension systems, capable of processing base fabrics with varying widths, delivering smooth and wrinkle-free surfaces post-coating. The equipment supports fully automated integrated operation, featuring stainless steel frame compliant with food-grade standards, serving as critical equipment for enhancing waterproofing and mechanical performance.

Automatic inner liner insertion machine, an automated equipment for woven bag production, designed for seamless integration of inner liners with woven bags. Utilizing dual-reel synchronous feeding and precision alignment mechanisms to achieve automatic insertion of liners into bag bodies, simultaneously completing open-end formation. Equipped with intelligent tension control system ensuring smooth adhesion without wrinkles. Modular structure supports specification changes, producing high-strength and airtight finished products.
