Single and Double Loop FIBC Bag with Air Releasing Vent

Faster filling without touching the filling machine

The problem it prevents

Your filling line is the bottleneck, and most people blame the machine.

During fast filling, the air pushed out by the incoming product has to escape somewhere. Without venting it blows the bag up, slows the filling rate, and pushes the bag out of shape so it will not stack square.

Filling is slow, bags come out fat and round, and the warehouse cannot stack them properly. The vent panel fixes it at a fraction of the cost of new filling equipment.

What it is

A single or double loop FIBC fitted with air releasing vent panels. With venting, the fill cycle is faster, the bag holds the shape it is meant to hold on the pallet, and the stack is more stable in the warehouse and in the container.

Key features

  • Single loop or double loop lifting arrangement
  • Air releasing vent panels for faster filling and discharge
  • Better shape retention and a more stable stack
  • Fabric grade and safe working load made to your requirement
  • Filling spout, discharge spout, flat top or flat bottom options
  • Custom printing available

How we build it

Our development work has been on where the vents are placed and how many are needed for a given fill rate and product density. Vents in the wrong place do very little. We work this out from your fill rate rather than copying a standard pattern.

Built to your specification

Every one of these can be changed for your application, and a sample is supplied for trial fitment before bulk production.
