Are you Confused Deciding Which Variety of Bulk Bag to buy?
Bulk bags are a well known packaging solution for large quantities of product for example aggregates and waste. They’ve many names which consist of, Tonne bags, Dumpy bags, FIBC’s, Builders bags. Get far more facts about Aggregates
The array of sizes and specifications of Bulk bags are vast and every type will suit a diverse use. The specifications can also be really detailed and technical which can often make it difficult to ascertain what type is going to be necessary for the expected use.
When deciding around the proper variety of FIBC, the following points need to be considered;
– Physical properties or chemical properties on the intended product to go inside the bulk bag, which include:
• Needed 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 needed
– The filling, handling, transporting, storing and emptying procedures with the FIBC.
See below for a complete rundown of terms for this common packaging solution and their which means. This will help to produce informed decisions regarding the type of bag required.
Terminology Details
Class of IBC = Single trip, normal duty reusable or heavy duty reusable.
Safe operating load (SWL) = this is the capacity with the bag and relates for the maximum weight or volume of product that the bulk bag can hold safely. It’ll generally be shown in kilograms and ranges from 250kg – 2000kg
Size = This may commonly be shown in external dimensions and in centimetres.
Safety aspect = Common tonne bags will have a safety issue of 5:1, which means a 1000kg capacity bag is guaranteed not to break, rip or tear using a weight of much less than 5000kg. A safety factor of 6:1, is usually a bulk bag produced out of thicker woven polypropylene body fabric and tested to a higher normal and is generally a heavy duty or multi trip FIBC.
Filling and discharging options
Plain base – This can be a Normal flat base on the bottom of the bulk bag which tends to make it cuboid in shape. All standard builders bags will come with a plain base.
Lifting loops – Powerful loops sewn into every single 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 – There are two sorts of filling inlets. They’re;
Filling spout – A extended tube which allows the contents to flow into the bag simply
Skirt prime – More fabric at the leading with the bag which can be secured around the filling device to stop any loss of contents, ensuring that each of the contents flow effortlessly into the IBC.
Baffles = Additional internal baffles are sewn onto the corners of 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 created out of woven polypropylene fabric is sewn onto the bottom of the bulk bag. This offers an a lot easier flow in the contents out the bag when held over a hopper as well as the contents discharged.
Food grade = Food grade manufacturing relates towards the conditions in which the FIBC has been manufactured and stored in prior to delivery to client. These conditions are based on strict requirements which enable the bag to be appropriate for use for foodstuffs. Food grade bulk bags usually come with an internal polythene lamination.
You can find two key forms of food grade situations;
Clean room = The manufacturing/storage facilities are free of loose threads, dirt and dust. Commonly much 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 suitable to package food components without having the risk of getting contaminated.
Liners – An internal polythene liner delivers added protection for the contents inside. Liner can either be:
• Inserted loosely or tabbed
• Cuffed, exactly where the liner is inserted along with the top rated section roll over the top of your bag to produce it additional safe.
• Tabbed, liner is stitched in spot in the corners to ensure stability inside the bag.
