Step 1: Sourcing & preparation�

The initial stage of our production process focuses on the sourcing and preparation of high-quality plastic materials.

  • Sourcing: We use 100% virgin polypropylene (PP) as the main material to ensure the best quality. Additionally, we incorporate carefully selected sub-materials, including color additives, UV stabilizers, TaiCal, and polyethylene (PE), to enhance performance and durability.
  • Preparation: The plastic is processed to meet the specifications required for subsequent steps.

Step 2: Mixing

Once the raw materials are prepared, the next stage is mixing, where the main and sub-materials are carefully blended to achieve the desired properties for FIBC bag production using advance technology and machinery.

​

  • Precision Blending: Virgin polypropylene (PP) is mixed with sub-materials such as color additives, UV stabilizers, TaiCal, and polyethylene (PE) in precise proportions to ensure consistency in quality and performance.

​

  • Uniform Distribution: Advanced mixing equipment ensures that all components are evenly distributed, enhancing the strength, flexibility, and UV resistance of the final product.

Step 3: Extrusion & Yarn Production

During the yarn production phase, we utilize advanced techniques and materials.

  • Melting & Filtration – PP resin and additives are melted and filtered to remove impurities.
  • Extrusion & Cooling – Molten PP is extruded through spinnerets and cooled into filaments.
  • Stretching & Strengthening – Filaments are stretched to enhance tensile strength and flexibility.
  • Winding & Storage – Final PP yarn is wound onto bobbins for the weaving process.

Step 4: Weaving

The weaving process contributes significantly to the strength and durability of FIBC.

  • Warp & Weft Arrangement – PP yarn is arranged in vertical (warp) and horizontal (weft) directions.
  • Circular or Flat Weaving – The yarn is woven using circular looms (for tubular fabric) or flat looms (for sheet fabric).
  • Fabric Strengthening – The woven fabric is designed for high tensile strength, durability, and load capacity.
  • Storage & Preparation – The fabric is rolled and stored for the next step: Coating

Step 5: Coating�

If the customer requires additional protection, the PP woven fabric undergoes a coating process to enhance its properties.

​

  • Lamination Process – A thin layer of PP or PE is applied to make the fabric water-resistant and dustproof.

​

  • Improved Strength – The coating adds extra durability and protection against moisture, UV rays, and contamination.

​

  • Customization Options – Coating thickness and material can be adjusted based on customer specifications.

​

  • Storage & Preparation – The coated fabric is rolled and prepared for cutting and printing.

Step 6: Cutting

Once the woven (or coated) fabric is ready, it is cut into specific sizes according to customer requirements.

​

  • Precision Cutting – Fabric is cut using automatic cutting machines or by hands for accuracy.

​

  • Customization – Different shapes and sizes are prepared based on bag design specifications.

​

  • Heat Sealing (if needed) – Edges may be heat-sealed to prevent fraying.

​

  • Preparation for Printing & Sewing – Cut pieces are stacked and sent to the printing or sewing process.

Step 7: Print & Sew

If required by the customer, the cut fabric undergoes printing to add branding or product information.

  • Custom Design – Logos, handling instructions, and product details are printed as per customer specifications.
  • Printing Methods – Uses flexographic for high-quality, durable prints.
  • Drying & Quality Check – Printed fabric is dried and inspected before moving to sewing.

​

Cut and printed fabric is stitched together to form the final FIBC bag structure.

  • Component Assembly – Body, bottom, top panels, lifting loops, and spouts are sewn together.
  • Reinforcement Stitching – Cross-stitching and overlock stitching ensure strength and durability.

Step 8: Quality Control and Packaging

Before packaging, each FIBC bag undergoes strict quality control to ensure it meets customer requirements and industry standards.

​

  • Load & Strength Testing – Bags are tested for tensile strength, seam durability, and weight capacity.
  • Visual Inspection – Checks for printing accuracy, stitching quality, material defects and metal contaminants.

​

  • Folding & Stacking – Bags are folded neatly and stacked for efficient storage.
  • Bale or Pallet Packing – Bags are packed in bales or on pallets, based on customer preference.
  • Labeling & Documentation – Each package is labeled with product details, batch numbers, and handling instructions.
  • Shipment & Delivery – Packed bags are loaded and shipped according to the customer’s delivery schedule.
