Bulk bags are a well known packaging solution for massive quantities of product for instance aggregates and waste. They've quite a few names which consist of, Tonne bags, Dumpy bags, FIBC's, Builders bags. Get extra details about Aggregates
The array of sizes and specifications of Bulk bags are vast and each kind will suit a various use. The specifications may also be fairly detailed and technical which can often make it tough to ascertain what variety is going to be necessary for the needed use.
When deciding around the ideal form of FIBC, the following points must be regarded;
- Physical properties or chemical properties of your intended product to go inside the bulk bag, such as:
• Expected volume
• Weight of product to be contained
• Bulk density
• Contents flow qualities
• Degree of aeration
• Particle shape and size
• Fill temperature
• Whether food grade is expected
- The filling, handling, transporting, storing and emptying methods on the FIBC.
See under for a full rundown of terms for this preferred packaging solution and their meaning. This will likely help to make informed decisions concerning the type of bag required.
Terminology Info
Class of IBC = Single trip, typical duty reusable or heavy duty reusable.
Secure functioning load (SWL) = this really is the capacity with the bag and relates to the maximum weight or volume of product that the bulk bag can hold safely. It is going to commonly be shown in kilograms and ranges from 250kg - 2000kg
Size = This may ordinarily be shown in external dimensions and in centimetres.
Safety aspect = Typical tonne bags may have a safety factor of 5:1, which means a 1000kg capacity bag is guaranteed to not break, rip or tear with a weight of significantly less than 5000kg. A safety factor of 6:1, can be a bulk bag created out of thicker woven polypropylene body fabric and tested to a higher regular and is usually a heavy duty or multi trip FIBC.
Filling and discharging attributes
Plain base - This can be a Standard flat base around the bottom of the bulk bag which tends to make it cuboid in shape. All common builders bags will come with a plain base.
Lifting loops - Robust loops sewn into each corner from the bag which allows it to be picked up and manoeuvred by a fork lift truck. All FIBCs will come with 4 lifting loops.
Filling inlet - You will discover two varieties of filling inlets. They're;
Filling spout - A lengthy tube which allows the contents to flow into the bag simply
Skirt best - Further fabric at the prime from the bag which may be secured around the filling device to stop any loss of contents, making certain that all of the contents flow simply in to the IBC.
Baffles = Extra internal baffles are sewn onto the corners on the bulk bag. This could help to stabilise the bag and make it extra rigid and are especially used for unstable or fluid products.
Discharge spout = A tube made out of woven polypropylene fabric is sewn onto the bottom of your bulk bag. This provides an easier flow on the contents out the bag when held more than a hopper and also the contents discharged.
Food grade = Food grade manufacturing relates for the situations in which the FIBC has been manufactured and stored in ahead of delivery to buyer. These circumstances are based on strict requirements which enable the bag to become suitable for use for foodstuffs. Food grade bulk bags typically come with an internal polythene lamination.
You will find two key sorts of food grade situations;
Clean room = The manufacturing/storage facilities are free of loose threads, dirt and dust. Normally additional suited to bird seed and animal feed
BRC compliant food grade bulk bags = manufactured and stored in stringent circumstances that meet the BRC requirements. This guarantees the food grade fibc is suitable to package food ingredients with no the danger of being contaminated.
Liners - An internal polythene liner supplies added protection for the contents inside. Liner can either be:
• Inserted loosely or tabbed
• Cuffed, exactly where the liner is inserted and also the leading section roll more than the prime of your bag to produce it more secure.
• Tabbed, liner is stitched in spot in the corners to make sure stability inside the bag.
