FIBCs
is called Flexible Intermediate Bulk Containers,
also known as “big bags”, “bulk sacks”, having
body made of flexible polypropylene woven fabric.
They
are first manufactured in the late 1950s or
early 1960s in America, Europe and Japan. The
first FIBCs were constructed with heavy-duty
PVC-coated polyester fabric and the initial
cost of these heavy-duty PVC containers is extremely
high. They are mainly used for multi-trip in
rubber industry with average loading capacity
of 2 metric ton per bag. Flexible Intermediate
Bulk Containers manufactured with polyolefin
fabrics were experimented in England, Japan,
Canada, and the United States at about the same
time in the late 1960s to the early 1970s. It
was the development of these high-strength light
weight fabrics (i.e., polypropylene) and the
specialized weaving technology that spurred
the growth of the Flexible Intermediate Bulk
Containers that are universally used today.

They have the following
characteristics:
- Cannot be handled manually
when filled. FIBCs make it possible for operators
to move large quantities of material easily
and efficiently around the working area by
using hoists or forklifts.
- Is intended for shipment
of solid material in powder, flake, or granular
form, convenient for transportation and storage.
- Does not require further
packaging. The cost of FIBCs is competitive
with other forms of packaging as it is usually
utilized without pallets.
- It can be folded flat and
bailed for shipment to the user. It can also
be folded and thus take up little storage
space in the working area after their contents
have been discharged. The weight of a bulk
bag used to ship one metric ton of product
weighs only 3.5-4.5kgs, offering a low package
product weight ratio. So it is easy for handling
and cost-effective.
- FIBCs can be manufactured
to meet specific requirements of the end-
users. The height of the container, the diameter
and length of the spouts, coated or uncoated
fabric, and whether a polypropylene liner
is necessary will be specified according to
the type of product that will be shipped.
It is user-friendly.
Generally, FIBCs is the ideal economical and
durable packaging material, which have been
widely used in various industries such as chemicals,
minerals, construction, plastics, agriculture,
food and pharmaceuticals, etc. |
