FIBC bags are manufactured by using polypropylene as the primary raw material, blending it with a small amount of stabilizing additives, extruding the mixture into plastic film via an extruder, cutting the film into filaments, and then stretching the filaments. The resulting high‑strength, low‑elongation PP monofilaments are heat‑set to produce a base fabric, which is subsequently woven and coated to form the plastic woven fabric. This fabric is then sewn together with straps and other components to create the space bag.

FIBC (flexible intermediate bulk containers) are manufactured primarily from polypropylene, to which a small amount of stabilizing additives is uniformly blended. The mixture is then melted and extruded into plastic film via an extruder, cut into filaments, and subsequently stretched. After heat-setting, this process yields high‑strength, low‑elongation PP monofilaments. These filaments are woven into a base fabric, which is further coated with a laminating layer to produce the final plastic woven bag. The finished bag is assembled with straps and other components to form a space‑saving bulk bag. Scope of application: chemical raw materials, food additives, construction materials, and any industry that utilizes FIBC packaging. In fact, FIBCs are a type of bulk bag. As a professional FIBC manufacturer, we proudly present our products. Our FIBCs feature lifting loops at all four corners; two or more of these loops have a load‑bearing capacity exceeding the rated capacity, ensuring that even if two loops were to break, the bag would remain fully usable.

FIBC straps strike a balance between artistry and practicality, offering consumers a fresh product‑selection experience that takes into account a wide range of factors. FIBC types vary greatly in style and exhibit clear differentiation; manufacturers tailor their designs to the specific application, factoring in vastly different considerations. In some cases, particular requirements for volume are essential—when the load is substantial, the bag must meet stringent dimensional specifications. Historically, such meticulous attention was not standard; while distinctions were made in appearance and size, the categorization remained rather simplistic, failing to address diverse needs. Today, however, designs are customized to align with users’ real‑world applications. The market now offers a wealth of product‑related insights: for instance, when sourcing in bulk, are there special requirements? And once price and quality have been established as reliable benchmarks, do further adjustments still need to be made to suit specific niche applications?

1. The load capacity of ton bags ranges from 0.5 to 3 tons.

2. Based on content, cargo is categorized into two main types: bulk cargo ton bags and small-package ton bags, suitable for both single-use and reusable applications.

3. Ton bags are classified into three shapes: round, square, and U‑shaped.

4. Lifting structures are available in top‑mounted, side‑mounted, and bottom‑mounted configurations, typically equipped with material inlet and outlet ports.

FIBC products have a wide range of applications, particularly for packaging bulk materials such as cement, grain, chemical raw materials, feed, starch, and minerals—whether in powder or granular form—as well as pharmaceutical ingredients, plastic resins, food additives, feed additives, refractory materials, and even hazardous substances like calcium carbide. They offer exceptional convenience during handling, transportation, and storage. FIBC products are currently experiencing robust growth, with particular popularity for one-ton capacity bags packaged on pallets—either one bag per pallet or four bags per pallet.
