Big Bag

Flexible container to transport and store bulk products, such as sand, gravel, grain, plastic granules, etc. Its woven fabric is UV-resistant. This solution can hold a maximum weight of 1.5 t per standard bag. It is available in reusable (safety factor 6:1) or single use (safety factor 5:1) versions. Our partners have many certificates and offer specific designs such as flexible silos for foodstuffs, silos for storing hazardous material or bags that can withstand 2-ton loads, etc.

The flexible silo can feature a filler neck suitable for each process to fill the bag while controlling the flow (prevents spillage).

To manage the flow rate during emptying, whether full or partial, the bag can be fitted with a discharge chute.

For easier material transfer, we offer bags with filler skirts, which (thanks to their additional fabric) can open up flexible containers fully and also prevent any external contamination or content spillage by closing them fully.

The bag topfull opening option is an optimised solution for filling in one go. Your bag therefore becomes a storage container.

The bag bottomfull opening option is used to quickly and easily empty the contents of the flexible silo in one go, while guaranteeing handler safety thanks to remote opening.

It is possible to close the bag bottom fully thanks to the flat bottom option. It is suitable for bag storage and transport only.

ManuLine can customise flexible containers with company colours by printing (on one or more sides) to give brands more visibility.

We also offer tailor-made bags. Feel free to contact us for specific requests (sizes, big bag types, etc.)

A versatile holder that optimises flexible container (Big Bag, FIBCs) storage and handling.

Easy to stack and unstack thanks to the cupped feet stacking system (no tools or bolts needed). Optimises BIG BAG storage areas thanks to stacking feature (1+3 stacking possible according to tube length and BIG BAG weight).

It features a frame, four tubes and a base. Each structure can hold up to 2 tons.

Filling is optimised when flexible containers are in holders (there are no pockets as the fabric is stretched unlike when big bags are stored on pallets) and there is no risk of tipping during handling which guarantees operator safety.

Our standard holders are available in 950 mm or 1200 mm centre-to-centre distances according to Big Bag sizes, but we also offer specific holders to fit other containers.

Thanks to its renowned expertise in handling, ManuLine offers custom-built solutions to meet your specifications.

The 1200 mm centre-to-centre distanceholders can be fitted with fork slots in the frame and base (according to handling equipment fork length).

The Holderwith wheels is perfect for moving Big Bags by hand safely and easily (non-stackable solution)

The Holder with duckboard is designed to store filtering Big Bags. It is ideal for collecting liquid (in the event of mud or industrial wastewater, for example).

We can also offer a safety chair for maximum handler safety when opening flexible container discharge chutes.

To reduce the overall height of the Big Bag storage holders and to avoid tearing the bag, ManuLine offers sheet or latticed steel base plates according to requirements and bag type.

Big Bag emptying station

ManuLine develops safe solutions for emptying flexible containers (Big Bags, FIBCs) quickly and without any spillage. These solutions are suitable for all sectors of industry and for frequent or occasional use.

The emptying station is made up of a top part holding the Big Bag and a bottom part featuring a discharge system and the product collection container.

Our stations are fully customisable (size, valve model, accessories, etc.).

Holder stacking and unstacking is quick, safe and easy thanks to the cupped feet stacking system.

Depending on usage, ManuLine offers several solutions to meet specifications:

Emptying station with hopper and sleeve(s): used to fit the hopper with one or more sleeves for emptying by suction. This emptying solution enables quick and easy product transfer.

Please note that ManuLine does not supply the suction system.

Emptying station with check valve or butterfly valve: makes it easier to empty small particle size products (<6 mm), such as powdery materials. Enables basic flow control during emptying.

Emptying station with diaphragm valve: used to empty your flexible containers by controlling the flow easily and accurately. The Big Bag can be replaced during emptying. The flexible container can therefore be emptied several times.

This solution is highly recommended for the agri-food sector. As the Big Bag contents do not come into contact with the station, no contamination is possible.

The Emptying station with seed valve is perfect for the agricultural sector. This solution is designed to direct the Big Bag flow into a seed drill thanks to its telescopic tube.

Emptying station withindustrial knife gate valve: it is designed for large particle size products (>6 mm), such as plastic granules, rubble, etc.

The product must be able to withstand crushing or cutting during valve opening and closing. This system is not designed to accurately control flow during emptying.

It is recommended for total emptying of the Big Bag.

We can supply a stainless steel version suitable for food use.

ManuLine offers specific solutions to optimise transfer of materials.

A filling chute can be fitted with wheels to make it easier to move the station.

Ideal for storing grain, cattle food or seed, this product is mainly intended for agricultural use. Our flexible storage silos are available in 4 or 7m³ versions with different feeder systems. Our standard structure is available with full opening (bucket filling for example).

Our galvanised steel structures feature a flexible silo. As the silo is made from breathable fabric, it must be protected from adverse weather conditions. It ensures good air flow and therefore prevents condensation in the bag, protecting it from any damage.

The fabric is UV-resistant.

The screw-feed system is used to keep the bag filler neck open (400 mm-diameter steel cylindrical inlet). Please note that ManuLine does not supply the feed system.

The pneumatic feed system is a containment solution. Featuring a steel tube with a long radius elbow and a 100 mm-diameter Guillemin coupling accessible from the ground, it is easy to install and use.

Quick and easy assembly and disassembly. The scissor valve is used to control flow rate during partial emptying.

The ManuLine team will meet your specific requests.
