China fibc bulk bags are designed for different uses and come in various forms. This makes them useful for packing many products and improving how products are stored and transported.
Standard FIBC bags
These are also called knitted bulk bags. They have a simple structure and work well for holding dry products like grains, powders, and sands. These bags are cheap and suitable for many uses.
Cross Corner FIBCs
These bags have their corners stitched in a cross pattern. This makes them very strong and suitable for heavy products. The better the stitching, the longer the bag will last. They work well in industries that transport heavy materials.
Conductive FIBCs
These bags are made from special materials that help reduce static electricity. They are suitable for packing fine powders like chemicals and clays because they avoid sparks that can cause fire or explosions. These bags are used safely in risky environments.
Heavy Duty FIBCs
As the name suggests, these bulk bags are made to be very strong and thick. They are good for carrying tough materials like cement, gravel, or metal scraps. They are very durable and can be reused many times.
Jumbo bags
Also called big bags or super sacks, these bulk bags are bigger in size and usually hold more than one ton of material. It's easy to handle and stack. Made for bulk products. Example: sands, minerals, and agricultural products.
Liner FIBCs
These bags have an inner plastic layer for extra protection against water and dust. Good for products that need to avoid moisture like food grains. The liner keeps the product fresh inside, even in bad weather.
Box-shaped FIBCs
These bags are designed in a cube shape to facilitate easy stacking. When loaded, they maintain their box shape to optimize space. Best suited for products like gravel, sand, and building materials.
U-panel and 0-panel FIBCs
U-panel bags are made from a single piece of material that forms a U-shaped panel, providing strength on three sides. 0-panel bags are designed with a sewn-in horizontal panel, making them cost-effective. Both types are used for heavy bulk materials.
When buying bulk bags, one needs to think about what the bags will be used for, how much weight they carry, what material they are made of, and how long they will last. It will help one choose the right bags for their needs and save money at the same time.
Usage and Material
Select the inner and outer fabric based on the contents and conditions dealt with. Examples: polypropylene (PP) bags for chemicals, and grains in sandy soils bulk bags for building materials). Polypropylene bags are affordable and last long in dry conditions. If the product is sensitive to moisture, choose a bulk bag with a liner.
Safety factors and working environment
Consider conductive FIBCs for explosive materials. This helps eliminate static charges. Heavy-duty bulk bags are needed for sharp items like glass and metal and for things like cement and gravel. Proper handling equipment and practices should be used depending on the FIBC type (e.g., fork, loop, crane). This will help everyone stay safe while working.
Weight
Pay attention to the bag's construction, as this is very important in doing this. People make FIBCs in different denier sizes. Bigger deniers mean the fabric is stronger. The bag's strength also depends on the weave: plain weaves are good for stacking, but twill is better for handling tough materials. Load a bulk bag carefully, and do not overload it. Sticking to the safe working load (SWL) is crucial to prevent accidents.
Handling and storing FIBCs safely
FIBCs must be folded or packed neatly and kept dry and out of the sun's heat. That means stacking them well. Only stack filled bags up to two bags high to avoid crushing the one at the bottom. When handling, do not drag the bags on the ground; this can damage them.
Choosing the right bag
Decide if a standard bag is enough or if a special bag is needed. Special bags like conductive bags for risky factories are available. A U-panel bag could be used if stability and easy stacking are essential.
Filling and discharge systems
If the filling method in the factory is a top fill, a bag with a top fill spout is appropriate. For the bags' discharge, if the materials need slow release, go for a spout closure, but if quick release is needed, a spout open bulk bag is ideal. Flat top bulk bags are the best when stacking the filled bags is important.
The specifications of China fibc bulk bags and their maintenance are important as inappropriate handling practices can reduce the lifespan of these bags. Therefore, this insight is vital when maintaining these bags.
Polypropylene
Plastic bulk bags are mostly made from polypropylene (PP) plastic. Polypropylene is easy to recycle, reusable more than once, resistant to moisture and chemicals, and can be produced in any required shape and size. The thicker the plastic, the stronger the bag will be.
Fibricost and weave
The strength of the bulk bag and the material inside depend on the fabric used and how the fabric is woven. For example, plain weaves provide better tensile strength and are supportive of woven sacks used in agriculture. Twill fabrics are tougher and can hold sharp stuff. Bigger denier offers better strength.
Joints
Joints hold the bulk bag's panels together. Double stitching gives better strength. Overlock can be used where the bag will have normal usage only. Taped joints are better for heavy-duty processes.
Spout
Fill spouts make it easy to add materials to the bulk bag. Spouts can be square or round, depending on the type of bulk bag. Larger spouts mean easy filling; smaller spouts reduce the chances of the product spilling out.
Care and maintenance of fibc bags
Handle FIBCs with care to avoid damaging their seams or fabric. Avoid dragging bags on sharp surfaces. Keep bags dry and avoid excessive exposure to sunlight. This can weaken the fabric over time. Clean bags before storage to prevent contamination. Store FIBCs in a cool, dry, and shaded area away from direct sunlight and moisture.
Reusable
The big bags can be reused many times. This makes them a cheap way to move things. They are better for the earth because they cut down on the number of new bags needed.
Different uses
Big bags can be used to move many things like grains, powders, and stones. They come in many designs to protect the contents just right.
Lightweight yet strong
FIBCs are strong but weigh little, making them easy to move around. Even if the bags weigh only a few hundred grams, they can carry over a ton. This helps in handling and cutting transport costs.
Well-designed for security
Bulk bags are designed to securely hold their contents. Many have extra features to keep the product safe from fire, moisture, and other risks. Examples: conductive FIBCs prevent explosions, and liner FIBCs keep things dry.
Saving space in transport and storage
FIBCs are stackable and foldable, saving space when empty or full. This helps reduce transport and storage costs. They can be packed tighter during transport to lower freight fees. When not in use, they fold flat to occupy less space in storage facilities.
Reduced static electricity
Special conductive FIBCs are available to manage static charges. This makes them safe when hauling flammable powders. These bags help lower static electricity, making them safer for moving sensitive ingredients.
Stronger and bigger
Bulk bags are tougher than smaller sacks like jute or hessian bags. They hold more product, too, usually up to a ton or more. More bulk means: fewer bags to buy and manage, and greater savings.
It's important to consider the type of material to be held and the surrounding environment. If it's water-sensitive stuff, go for a bag with a liner. For stuff that makes static, conductive bags are better. Also, think about the filling and emptying methods. They should match how the bag will be used.
Most bulk bags are made of polypropylene because it doesn't break down easily and won't harm the environment. Some FIBCs have a treatment that makes them conductive to reduce static electricity. Liners of plastic can be placed inside the bags to keep water out and deliver extra protection.
Prolonged exposure to sunlight can weaken the polypropylene and linen material. It is best to keep the bags in a dry, cool place away from direct sunlight. If that's not possible, use a cover to shield the bags from the sun.
SWL refers to safe working load. SWL is the maximum weight a bag can carry safely without risking damage. Overloading bags can cause seams to rip and fabric to tear, putting people and things at risk. Always follow the SWL guidelines printed on the label of every FIBC bulk bag.
With proper care and maintenance, these bulk bags can be reused 5-10 times. Some heavy-duty bulk bags made for tougher tasks can be reused even more - 15 times or so. Cleaning the bags and avoiding excess wear will help them last longer.
