To correctly determine the big bag sizes you need, you should consider the following points:
Density of the product packed in the big bag (each product has its own specific density)
Special conditions for bulk bag filling and discharging:
If you have a filling machine, you must choose the bag size within the sizes of the machine. If your customers have limited handling or lifting capabilities, you must comply with their requirements.
Product transport and storage conditions
The width, length and height of the vehicle on which the bags will be transported (truck, container or train car, ship) play an important role in determining the dimensions of a bigbag. In addition, the dimensions of the shelves and the warehouse to be stacked must also be taken into account.
MAXIMUM USE OF TRUCK SPACE
Since bulk bags are usually transported in trucks that are approximately 2.46 m wide and 13.6 m long, the most common sizes for a big bag are:
BIGBAGs ON PALLET
Since bigbags are usually placed on the pallet, the dimensions of the bag can also be selected according to the pallet dimensions. For a Europallet with a bottom of 80×120 cm, similar but slightly smaller sized bags should be preferred. An optimized FIBC for a Europallet is usually a Q-bag.
SQUARE AND RECTANGULAR BASED BAGS
Width and Length equity (square)
There is no need to worry about which side is correct during use. When the difference between the sides is small (eg 91×95 cm) and there isn’t any print It’s hard to tell the difference. There is no restriction on how you can lift the FIBC with a forklift. Insufficient use of the space on the pallet may occur with this type of bags.
Space can be used to the maximum. (For example on pallet). However, calculation may be required for lifting and handling.
Slingsan can also produce other sizes upon your request. Even extraordinary dimensions such as 50 * 50 * 50 cm or 200 * 400 * 280 cm are no deal.
Our standard PP fabric widths used in the production of FIBC (external dimensions) are 70 cm, 75 cm, 80 cm, 85 cm, 91 cm, 95 cm, 100 cm, 105 cm, 110 cm, 115 cm and 120 cm.
Since there is no standard big bag height, it can vary between 50 cm and 280 cm. For the stability of a FIBC, it is not recommended that the height be greater than twice the short side. The height is determined by adding +10% free space to the amount of material required for easier filling.
Bigbag size consists of the width, length and height of its body. The dimensions of the inlet and outlet of the big bags and the spout length are not considered as part of the FIBC size.
OUTER AND INNER DIMENSIONS
When determining the Big Bag dimensions, it should be noted that the outer and inner dimensions are not equal. The outer size of a bag is 4 cm larger than the inner size. (For example, if the outer dimension is 95×95 cm, the inner dimension is 91×91 cm). The outer dimension is measured from the beginning to the end of the fabric, while the inner dimension is measured from seam to seam. The volume that can be used for the packaging material should be calculated based on the internal dimensions.
FLEXIBILITY OF THE BAG (belly)
When a big bag is filled with material, its diameter is approximately 25 cm larger than the size of an empty big bag. This problem can be solved by placing panels on the corners of the big bag to prevent the belly after filling. The diameter of this type of product increases only by 10-15 cm. This type of bag is called Q-Bag.
Single and Double Loop
Big bags with one or two loops are made of tubular fabric in sizes from 60 x 60 cm to 95 x 95 cm. There is no difference between inner and outer dimensions of these bags.
