FIBC manufacturing process is a detailed and highly coordinated operation that demands precision, consistency, and stringent quality control. At EPP Vietnam, we have perfected this process over nearly two decades, ensuring every jumbo bag that leaves our facility meets international standards and exceeds customer expectations. Let us take you behind the scenes of our production facility to show how we turn raw polypropylene into durable, high-quality FIBCs ready for global export.
Raw Materials: The Backbone of Quality
The foundation of every superior FIBC manufacturing process lies in the quality of its raw materials. At EPP Vietnam, we use virgin PP (Polypropylene) and HDPE (High-Density Polyethylene) resins, selected and imported from globally recognized suppliers. To enhance product performance, we incorporate additives such as color masterbatch, UV stabilizers, antistatic agents, non-flammable compounds, and conductive carbon yarns. These materials are chosen based on the specific technical requirements of each order to guarantee durability, UV resistance, and safety under varying conditions.
Extrusion: Creating High-Quality Yarn and Film
In the FIBC manufacturing process, extrusion is the next vital step. Once the raw materials are selected, they are fed into our high-efficiency extrusion systems. Our extruder machines, with capacities ranging from 450 to 650 kg/h, are sourced from globally renowned manufacturers including Starlinger, Lohia, Hana, Hengli, and Yong Ming. These machines melt and stretch the plastic into high-tensile yarn with consistent denier and elongation, ensuring optimal weaving performance.
In addition to yarn production, our monofilament-making machine (200 kg/h) produces specialized mono yarn for high-strength applications. Meanwhile, our plastic film blowing machines (160 kg/h) generate PE film ranging from 1500 mm to 4500 mm in width, used as liners inside FIBCs for moisture protection and food-grade containment.
Weaving: Fabric and Loop Production
The FIBC manufacturing process continues with weaving. After extrusion, the yarns are woven into fabric using circular loom machines that operate at speeds of 60–100 RPM. These looms produce tight, high-density fabric rolls in widths ranging from 900 mm to 2200 mm. The woven fabric forms the core body of our FIBC bags, offering both strength and flexibility.
For the lifting components, our ribbon looms (80–150 m/h) produce strong and durable loops in widths from 20 mm to 110 mm. These loops undergo rigorous strength testing to ensure they can safely handle payloads of 500 kg to 2000 kg or more, depending on the bag’s design.
Lamination: Ensuring Adhesion and Waterproofing
Lamination is a key phase in the FIBC manufacturing process, enhancing the protective qualities of our FIBC bags. Our high-speed lamination machines, operating at 60–120 meters per minute, apply a coating layer of 15–30 grams per square meter. This step ensures water resistance and improves printability while maintaining the fabric’s flexibility.
We use lamination systems sourced from advanced manufacturers in Taiwan, China, and India, ensuring reliable adhesion for applications in humid or wet environments and extending the product lifespan.
Cutting: Precision for Semi-Finished Products
Precision cutting is vital to ensure consistency in size and shape across all FIBC components in the FIBC manufacturing process. Our fabric cutting machines produce 15–20 pieces per minute, tailored to customer-specified dimensions with minimal material waste.
Simultaneously, our belt cutting machines can process 1–6 belts at a time, producing 30–60 pieces per minute. This dual-system cutting setup maximizes throughput while ensuring dimensional accuracy, a crucial factor for downstream processes like printing and sewing.
Printing: Sharp and Accurate Branding
Branding and product information are added using advanced flexographic printing technology in the FIBC manufacturing process. Our 3–5 color Flexo printing machines deliver output speeds of 200–1200 pieces per hour, enabling us to meet large-volume orders efficiently.
Using high-quality ink and expert calibration, we produce sharp, smudge-resistant prints with excellent adhesion. Whether it’s logos, safety instructions, or batch numbers, every print aligns with our clients’ branding and regulatory requirements.
Sewing & Finishing: Sustainable Crafting FIBCs
Sewing is where our FIBC bags come to life. With sewing machines operating at 800–1200 RPM, we accommodate a range of sewing techniques, including single-needle, double-needle, overlock, and chain stitch configurations.
This step of the FIBC manufacturing process involves our skilled sewing technicians meticulously assembling each component, from attaching loops and spouts to integrating liners. This stage requires careful attention to detail to ensure load-bearing performance, leak-proofing, and ease of handling.
Inspection: Quality Assurance at Every Step
At EPP Vietnam, quality assurance is integrated throughout every stage of the FIBC manufacturing process. Our experienced QC team uses specialized testing equipment to inspect yarn strength, fabric density, loop durability, lamination adhesion, and print quality.
Each finished bag undergoes load testing, dimensional checks, and visual inspections before approval. We follow internationally recognized standards such as ISO 9001, ISO 22000, and FSSC 22000 to ensure full compliance with safety and hygiene regulations.
Packaging: Safe and Hygienic Loading
Packaging is not just about aesthetics — it’s about protecting the product until it reaches the customer. Our baling press machines, operating under pressures of 15–20 MPa, compress FIBC bags into compact, stable bundles suitable for export.
All packaging is conducted in a clean environment with strict supervision during container loading. This process ensures the product remains hygienic and damage-free during transportation.
Delivery: Reliable and On-Time Shipping
With years of experience in international logistics, EPP Vietnam guarantees safe, flexible, and on-time delivery to more than 30 countries worldwide. We work with reliable global shipping partners to offer air, sea, and multimodal transport options tailored to your timeline and budget.
Our logistics team monitors each shipment closely, ensuring full documentation, compliance, and real-time updates for our clients.
FAQ
Q1: What are FIBCs, and what are they used for?
FIBCs (Flexible Intermediate Bulk Containers), also known as jumbo bags or bulk bags, are large woven containers made from polypropylene fabric. They are widely used for transporting and storing dry, flowable products such as grains, fertilizers, chemicals, cement, plastic granules, and food ingredients.
Q2: Are FIBCs environmentally friendly?
Yes, FIBCs can be an eco-friendly packaging option. At EPP Vietnam, we manufacture FIBCs using virgin polypropylene, which is recyclable. Additionally, our manufacturing process minimizes waste, and many of our FIBCs are reusable depending on their design and application.
Q3: What is the production capacity of EPP Vietnam?
EPP Vietnam has a production capacity of approximately 6 million FIBC units per year. Our modern facilities and streamlined processes allow us to fulfill both small and large-scale orders with consistent quality and short lead times.
