Filling bulk bags ( aka… FIBC fillers, supersack fillers, big bag filling , and bulk sack ) requires consideration and balancing of these factors:
Filling a few bags per day
Filling a few bag per hour
Filling many bags per hour
Is the system to be dedicated to one size bag, or a few of similar size ?
Or, system to be capable of many or any size bag ?
What range of bag heights ?
Range of bag cross section (width) ?
Range of bag weights ?
Might the system also need to fill drums, gaylord or portable bins ?
Does the product value justify a high accuracy feeding system ?
Does the product value justify a high precision scale(something better than just NTEP certified ) ?
What is the smallest and largest weight to be filled?
Traversing/Sliding strap hangers
Is a hopper required over the filler ?
What is the headroom in the area ?
Adjustable fill heights ?
Programmable fill heights ?
Is pre-weighing required ? (sometimes suggested for high speed systems)
Product Compaction & Bag Stability
Granular product, where gravity compaction is sufficient ?
Fluidizable product, requiring extra time to de-aerate ?
Fluffy product that demands tamping, vibration, and/or vacuum de-aeration ?
Dense powder that requires "tabling" to yield a flat bottom on the filled bag ?
Bag Closing & Package Handling
Will a forklift remove the finished bag by lifting it with a skid ?
Should the finished bag be shuttled or conveyed "downstream" for closure ?
Is accumulation of filled bags necessary ? (normally yes, for high output systems)
Is a pallet dispenser or slip sheet dispenser advisable ? (again, yes, for high speed filling)
Portability & Environment
Will the system be stationary ?
Or, must the filler be forklift portable ?
Does the service area require ATEX design ?
