Filling a big bag

A bigbag ( English for large sack or large bag ) is a flexible bulk material container that looks and can be used like a large sack or a large bag (with handles / loops). The internationally used abbreviation is FIBC and stands as an abbreviation for Flexible Intermediate Bulk Container (English for flexible intermediate container for bulk goods ).

A big bag holds about 1000 to 1300 liters. The maximum filling weight is indicated on the outside and is usually 1000 kg. It consists of a stable plastic fabric and can be refilled after emptying and, if necessary, cleaning, so it is reusable. Waste disposal companies mostly use disposable bags, which are incinerated if they contain flammable contents. Several stable loops are sewn on the open side, by which the container can be lifted for filling, transport or emptying. But there are also big bags available with an upper apron to close or with sewn-on filler or outlet nozzles. The fabric used is, for reasons of tightness and moisture protection, usually made of polypropylene , is provided or in part with an inner coating lined with foil liner. A large big bag fills the area of ​​a Euro pallet and is filled to a height of approx. 1.5 meters.

With some bulk goods, due to their properties, the dust-free and metered emptying of the big bag causes problems. Special big bag dispensing machines have been developed for these cases.

Big bags are often used in disposal technology for lighter waste materials such as paper and scraps , but also for the construction of cofferdams .

In Rhöndorf , a district of Bad Honnef , big bags were set up in the vineyard in spring 2014 to ward off an assumed risk of falling rocks. After several reports, the big bags were accepted from an occupational health and safety point of view.

Big bags must meet the safety requirements of the Equipment and Product Safety Act (GPSG). The importer is responsible for compliance, if applicable. The load capacity of big bags (except hazardous goods big bags) is tested according to the ISO 21898: 2004 standard.
