Building Merchants bags, also known as 1000kg bulkbags, tonne bags, single trips, dumpy bags, chubby bags, 1 tonne bags, 1 ton bags. These are the most basic of all FIBCs, made from 135gsm woven polypropylene fabric, as the name suggests this is what the building merchants, store supply and deliver their sand and aggregates in. The bags are intended to be used once and as such are classed as single trip, ie filled once and once empty disposed of. However they are a handy size for re-usable as lightweight domestic applications eg. general waste disposal, garden waste etc. We can custom print these 1 sided or supply them unprinted.
