Four loop polypropylene big bag

The four-loop soft container (Big Bag) has four loops made in the form of an extension container’s body. Four loop big bags have a large number of modifications of both the upper and the lower part of the container.

Four-loop polypropylene containers are mainly used for transportation and storage of biofuels as well as in the metallurgical industry, less commonly used in the mining and agricultural sectors. Big bags with a frill or open top, the lower part with a solid bottom, less often with the lower valve and without a polyethylene liner are used for transportation and storage of biofuels (pellets, briquettes).

In metallurgy they are used to transport pitch, copper sulphate, iron sulphate, ferroalloys and more. It is possible to use a liner or a two-layer fabric.
