Bulk bags are a well-known packaging solution for large quantities of product such as aggregates and waste. They have numerous names which involve, Tonne bags, Dumpy bags, FIBC's, Builders bags. Get extra information about Aggregates
The array of sizes and specifications of Bulk bags are vast and each and every kind will suit a different use. The specifications also can be rather detailed and technical which can often make it hard to decide what sort might be required for the expected use.
When deciding on the ideal form of FIBC, the following points must be regarded as;
- Physical properties or chemical properties with the intended product to go inside the bulk bag, for example:
• Required volume • Weight of product to be contained
• Bulk density • Contents flow traits • Degree of aeration • Particle shape and size • Fill temperature • No matter whether food grade is expected - The filling, handling, transporting, storing and emptying solutions from the FIBC. See beneath for any full rundown of terms for this well known packaging solution and their which means. This will likely help to produce informed choices about the type of bag required. Terminology Data Class of IBC = Single trip, typical duty reusable or heavy duty reusable. Protected operating load (SWL) = that 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 can usually be shown in external dimensions and in centimetres. Safety aspect = Common tonne bags may have a safety issue of 5:1, which means a 1000kg capacity bag is assured to not break, rip or tear having a weight of less than 5000kg. A safety aspect of 6:1, is really a bulk bag made out of thicker woven polypropylene physique fabric and tested to a larger normal and is generally a heavy duty or multi trip FIBC. Filling and discharging options Plain base - This can be a Regular flat base on the bottom on the bulk bag which tends to make it cuboid in shape. All regular builders bags will come with a plain base. Lifting loops - Powerful loops sewn into every single corner of your bag which permits it to become picked up and manoeuvred by a fork lift truck. All FIBCs will include 4 lifting loops. Filling inlet - There are two kinds of filling inlets. They are; Filling spout - A long tube which makes it possible for the contents to flow into the bag simply Skirt best - Added fabric at the top in the bag which is usually secured around the filling device to prevent any loss of contents, making sure that each of the contents flow simply into the IBC. Baffles = Extra internal baffles are sewn onto the corners with the bulk bag. This can help to stabilise the bag and make it much more rigid and are particularly used for unstable or fluid products. Discharge spout = A tube created out of woven polypropylene fabric is sewn onto the bottom in the bulk bag. This provides an less complicated flow with the contents out the bag when held over a hopper plus the contents discharged. Food grade = Food grade manufacturing relates towards the conditions in which the FIBC has been manufactured and stored in ahead of delivery to buyer. These conditions are primarily based on strict requirements which enable the bag to become suitable for use for foodstuffs. Food grade bulk bags normally include an internal polythene lamination. You can find two principal types of food grade conditions; Clean room = The manufacturing/storage facilities are free of loose threads, dirt and dust. Generally a lot more suited to bird seed and animal feed BRC compliant food grade bulk bags = manufactured and stored in stringent situations that meet the BRC standards. This ensures the food grade fibc is suitable to package food components with out the risk of becoming contaminated. Liners - An internal polythene liner gives added protection for the contents inside. Liner can either be: • Inserted loosely or tabbed • Cuffed, where the liner is inserted as well as the leading section roll over the top on the bag to create it far more safe. • Tabbed, liner is stitched in location in the corners to ensure stability inside the bag.
