Bulk bags are a common packaging solution for big quantities of product including aggregates and waste. They have numerous names which involve, Tonne bags, Dumpy bags, FIBC's, Builders bags. Get much more information and facts about Aggregate Suppliers
The range of sizes and specifications of Bulk bags are vast and every kind will suit a unique use. The specifications also can be fairly detailed and technical which can at times make it hard to ascertain what sort will be necessary for the expected use.
When deciding on the suitable form of FIBC, the following points need to be regarded as;
- Physical properties or chemical properties from the intended product to go inside the bulk bag, including:
• Needed volume
• Weight of product to become contained
• Bulk density
• Contents flow traits
• Degree of aeration
• Particle shape and size
• Fill temperature
• Regardless of whether food grade is necessary
- The filling, handling, transporting, storing and emptying approaches with the FIBC.
See below for any complete rundown of terms for this popular packaging solution and their meaning. This will likely help to make informed choices about the form of bag needed.
Terminology Info
Class of IBC = Single trip, standard duty reusable or heavy duty reusable.
Safe working load (SWL) = this is the capacity from the bag and relates to the maximum weight or volume of product that the bulk bag can hold safely. It is going to typically be shown in kilograms and ranges from 250kg - 2000kg
Size = This will normally be shown in external dimensions and in centimetres.
Safety issue = Normal tonne bags will have a safety issue of 5:1, meaning a 1000kg capacity bag is guaranteed not to break, rip or tear using a weight of less than 5000kg. A safety factor of 6:1, is actually a bulk bag produced out of thicker woven polypropylene body fabric and tested to a greater typical and is generally a heavy duty or multi trip FIBC.
Filling and discharging characteristics
Plain base - This is a Standard flat base on the bottom in the bulk bag which makes it cuboid in shape. All regular builders bags will include a plain base.
Lifting loops - Powerful loops sewn into each corner with the bag which enables it to be picked up and manoeuvred by a fork lift truck. All FIBCs will come with 4 lifting loops.
Filling inlet - There are two varieties of filling inlets. They're;
Filling spout - A long tube which allows the contents to flow in to the bag quickly
Skirt top - More fabric in the major of your bag which may be secured around the filling device to stop any loss of contents, ensuring that all the contents flow simply in to the IBC.
Baffles = Additional internal baffles are sewn onto the corners in the bulk bag. This could help to stabilise the bag and make it much more rigid and are especially used for unstable or fluid products.
Discharge spout = A tube produced out of woven polypropylene fabric is sewn onto the bottom with the bulk bag. This delivers an less difficult flow from the contents out the bag when held over a hopper as well as the contents discharged.
Food grade = Food grade manufacturing relates for the circumstances in which the FIBC has been manufactured and stored in just before delivery to consumer. These circumstances are based on strict requirements which permit the bag to become suitable for use for foodstuffs. Food grade bulk bags typically include an internal polythene lamination.
You will find two principal varieties of food grade situations;
Clean room = The manufacturing/storage facilities are free of loose threads, dirt and dust. Normally more 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 appropriate to package food components without the need of the risk of being contaminated.
Liners - An internal polythene liner offers added protection for the contents inside. Liner can either be:
• Inserted loosely or tabbed
• Cuffed, where the liner is inserted and the best section roll over the major of the bag to create it far more safe.
• Tabbed, liner is stitched in spot at the corners to ensure stability inside the bag.
