Inner Bracing Jumbo Bag

The inner reinforcement ton bag is an enhanced structural product of the flexible intermediate bulk container (FIBC). By adding reinforcing ribs inside the bag, it improves the stability of loading and stacking performance, and is widely used in the transportation of bulk materials for international trade. The inner reinforcement ton bag is mainly used in fields such as chemicals, building materials, minerals, and grain and feed, mainly because the inner reinforcement structure can effectively prevent the bag from deforming or collapsing after being filled with materials, and can also increase the stacking height, saving storage and transportation space.

1. European and American market: Focuses on environmental compliance, requiring compliance with standards such as EU REACH and US FDA (for food-grade materials), and is often used for the transportation of fine chemical raw materials and granular grains.
2. Southeast Asia / Middle East market: Focuses on high cost-effectiveness and durability, mostly used for heavy materials such as sand, cement, and fertilizers, with a high requirement for stacking layers.
3. Australian market: Has strict requirements for UV resistance, the inner reinforcement material needs to have weather resistance, and is suitable for outdoor storage scenarios.

Structural Features
1. Material of the reinforcing strips: Usually made of polypropylene (PP) braided strips, which are consistent with the material of the bag body and have high strength compatibility.
2. Layout of the reinforcing strips: Common designs include 4 reinforcing strips or 6 reinforcing strips. They are vertically fixed at the four corners or sides of the bag body, connecting the upper and lower bottoms to form a supporting framework.
3. Connection process: Using industrial sewing machines for double-line sewing to ensure uniform tension between the reinforcing strips and the bag body, and to prevent detachment.

Product Features
1. Structural Parameters: The material of the inner reinforcing ribs (usually polypropylene PP, the same as the bag material), the number of ribs (commonly 4 ribs or 6 ribs), and the connection process between the reinforcing ribs and the bag body (the degree of sewing firmness).
2. Certification Standards: Internationally, ISO 21898 (FIBC Safety Standard) is widely recognized. It is divided into four types: A/B/C/D. The corresponding type needs to be selected based on the electrostatic sensitivity of the loaded materials.
3. Additional Functions: Some customers may request to be equipped with discharge ports (Spout), dust-proof covers, and strap reinforcement, etc. The inner reinforcing rib structure must be compatible with these accessories.
