Baffle / Q-Bag FIBC A four-panel FIBC with internal baffles or corner ties that hold a near-cube shape whether the bag is empty or part-filled. Built for loads that have to stack square in a container or on a pallet without the bag slumping.

Concrete Washout Bag A fabric bag placed where concrete wagons are washed out, so solids settle and the water can be handled separately. It keeps washout out of drains and site ground; the water rules remain the site's.

Container Liner A liner that turns a 20 ft or 40 ft container into a bulk carrier: it protects the cargo from the container and the container from the cargo, and it is filled and emptied through built-in ends.

Dewatering Bag A woven bag made with geotextile fabric so water drains out while the solids stay in. It is sized from the sludge, the flow and the containment requirement rather than from a working load alone.

Dumpster / Skip / Yard Bag A heavy-duty open-top bag for construction, yard and mixed waste, lifted by four loops or handled by fork sleeves. It is built for abrasion and puncture, not for dust control.

Food-grade FIBC A bulk bag built around hygiene rather than around load: liner choice, closure, foreign-body control and batch traceability are the decisions that matter. The requirements that apply are confirmed per market and per project.

Four-Panel FIBC A four-panel FIBC is built from four separate body panels joined at the vertical corners, giving the tightest dimensional control in our woven polypropylene range. It is the family to choose when a filled bag has to keep a rectangular footprint and print square on every face.

One-Loop / Two-Loop FIBC A bag lifted from one or two central loops instead of four corner loops. It suits light to medium loads handled by a single hook or crane where loop alignment is the operator's main constraint.

Tubular / Circular FIBC A seamless circular woven bag for free-flowing powders and granules; the lowest-cost standard construction where stackability is not the deciding factor.

U-Panel FIBC A flat-bottom FIBC whose body is one U-shaped panel joined to two side panels, giving a squarer filled footprint than a tubular bag. It is the usual answer when a filled bag has to sit level in a stack at a workable sewing cost.

Ventilated FIBC A woven bag with mesh panels or a perforated body so air moves through the load. It is specified for produce, wood and other materials that must not sweat in storage.
