The Standard Bag features cross corner loops sewn into the corners of the bag. Each end of the loops is securely stitched into one side of the FIBC, providing excellent stability and strength for handling and transport. This design ensures even weight distribution and facilitates easy lifting from all sides. The Standard Bag comes in two types of construction: U-Panel and 4-Panel.

• U-Panel Construction: U-panel bags are constructed with three body panels: one that runs the full length of the bag forming the bottom and two sides, and two additional pieces of fabric sewn into the larger piece that form the other two sides. U-panel bags maintain a square shape when filled, especially when equipped with baffles. They are an industry standard and the most popular type of construction, offering high safe working loads (SWLs) and solid durability.

• 4-Panel Construction: 4-panel bags are constructed with four individual pieces sewn together to form a square structure. When filled, a 4-panel bag will hold its square shape similar to other construction types. Typically, 4-panel bags hold their shape better than U-panel bags, and U-panel bags hold their shape better than circular bags. The primary drawback of 4-panel bags is the large amount of stitching required, which can create more areas prone to failure. However, 4-panel bags are ideal for storage due to the way they hold their shape when filled.

The Full Loop Bag features continuous lifting loops that extend from the bottom to the top of the bag, forming a full loop structure. This design enhances the bag's strength and stability, making it ideal for heavy-duty applications. The loops are securely stitched into the sides of the FIBC, ensuring even weight distribution and facilitating easy lifting from any angle. The bag also includes a cylindrical spout at the top for convenient filling and discharge. This robust construction is perfect for industries requiring durable and reliable bulk packaging solutions.

Standard FIBCs are flexible and can bulge at the sides when filled, losing their square shape. Baffles, which are additional fabric panels or strings sewn into the four corners of the bag, help maintain the bag's square shape when filled. This reinforcement makes them easier to store side by side or stack.

The most common types of baffled bulk bags include Circular, U-panel, and 4-panel constructions:

​

• Circular Baffle Bags: These bags have four tubes forming each corner, with the sides sewn into the corners to create the bag, often referred to as an 8-panel baffle bag. Despite their tubular construction, Circular Baffle Bags maintain a square shape when filled, as shown in the bird's-eye view.

• U-panel Baffle Bags: Constructed with three body panels, one that runs the full length of the bag forming the bottom and two sides, and two additional pieces of fabric forming the other two sides. U-panel bags with baffles maintain a square shape when filled.

• 4-panel Baffle Bags: Made with four individual pieces sewn together to form a square structure. When filled, these bags hold their square shape well. Typically, 4-panel baffle bags retain their shape better than U-panel baffle bags, and U-panel baffle bags hold their shape better than circular baffle bags.

Circular Bags are constructed from a tubular piece of fabric that forms all sides of the bag, requiring stitching only at the top and bottom. Despite the tubular fabric, advanced sewing technology enables circular construction bags to maintain a square shape when filled. A common misconception is that circular bags will be round when filled, but they actually retain a square or rectangular shape, though less rigidly than other construction types. They are named "circular" because they are made from a single piece of fabric that creates all four sides of the bag.

Sleeve Lift/Lift Tunnel loops are a specialized type of loop made from the bulk bag's body fabric. They are an ideal choice for operations that exclusively use forklifts to lift and move FIBCs. If forklifts are your primary method for handling bulk bags, then bags with sleeve/tunnel lift loops are a highly practical option. These loops can be positioned either at the bottom or the top of the bag, depending on your specific needs. Placing sleeve/lift loops at the bottom of the bag can be especially advantageous when height clearance is a concern.

The Hood/Covered Lift Loop option is crafted from the same fabric as the bag and connects two corners of the bag to the other two corners, forming one large loop. Like sleeve lift loops, they are commonly used with forklifts for easy handling and transport.

Stevedore straps or lift loops are specially designed for the safe handling of bulk bags. Unlike bags with four loops that require lifting at all four points, Stevedore loops enable lifting equipment to lift from just one or two points, depending on the type. There are three different types of Stevedore straps:

Supporting Stevedore Loops (Standard Stevedore Loops): These are additional loops attached to each corner loop, providing extra support for safe handling.

Stevedore straps or lift loops are specially designed for the safe handling of bulk bags. Unlike bags with four loops that require lifting at all four points, Stevedore loops enable lifting equipment to lift from just one or two points, depending on the type. There are three different types of Stevedore straps.

​

Double Stevedore Loops: These are two loops that link each pair of parallel corner loops.

Stevedore straps or lift loops are specially designed for the safe handling of bulk bags. Unlike bags with four loops that require lifting at all four points, Stevedore loops enable lifting equipment to lift from just one or two points, depending on the type. There are three different types of Stevedore straps.

​

One Stevedore Loop: This is a single loop threaded through the four standard corner loops, connecting them all together.

Also known as Corner Seam Loops and Loop-Over-Loop, Side Seam Loop Bags are the most commonly used lift loop construction. In this design, a lift loop is sewn into the seam of the bag, allowing it to be lifted by a forklift using all four loops simultaneously. This can make filling and transportation more tedious compared to other loop options. Key features of loop-over-loop FIBC straps include:

​

• Corner seam loops are the standard and most common type of lift loops.

• Each corner of the bag features one loop.

• The bag can be lifted by a forklift, but all four loops must be used.

1 & 2 Loop FIBCs, also referred to as single and double loop designs, are highly efficient containers widely used in industries such as agriculture and cement. These FIBCs feature either one or two integral lifting loops, providing ease of handling and cost-effective packaging solutions. Designed to accommodate automated filling lines with options for liners and various base configurations, they ensure reliable transportation and storage of bulk materials while minimizing plastic packaging weight.

Bitumen bulk bags in pyramid shape are designed for the efficient storage and transportation of hot liquid bitumen. Featuring a polypropylene liner that can tolerate temperatures up to 120°C, these bags are ideal for carrying 1000 kg (1 ton) of liquid bitumen. The pyramid shape ensures they stand upright during filling, providing stability and preventing spillage. Additionally, the entire material of the bag melts with the bitumen, ensuring a seamless and efficient transfer process.

Bitumen bags in cubic shape are designed to carry 300 kg of bitumen and are encased in a lightweight metallic cage to maintain their structure. These bags feature a polypropylene liner that tolerates temperatures up to 120°C, allowing them to securely hold hot liquid bitumen. When emptying, the entire bag melts with the bitumen, ensuring an efficient and clean transfer process. The metallic cage provides stability and ease of handling, making them ideal for transporting bitumen.
