Formstable 4-Loop big bags – superior stability optimizes transport and storage

Formstable 4-Loop big bags with Baffle

We achieve the form-stability by sewing polypropylene “baffles” to sides of the bag, across each of the four corners. So when the bag is filled, the baffles prevent the sides from bulging out – a stable, cube shape is achieved.

Formstable 4-Loop big bags with Liners

Standard 4-Loop bag can also attain form-stability when fitted with Formstable Liners. These polyethylene liners are constructed with inner, heat-welded corner panels that give the liners (also the outer bags) a cube shape when filled.
