We have established a vertically-integrated production systems to provide products and solustions for packaging in a wide range of industries. We manage all aspects of products from development; such as weaving, coating, printing & sewing, to delivery process.

Quality is in the details!

At every step of manufacturing process, we ensure high levels of discipline and quality standards.

To meets all relevant industry and/or regulatory requirements, our state-of-the-art, in-house laboratories equipped with the Test Rig Machine to ensure the safe working load (SWL) of FIBC as per ISO standard. Also we has a complete traceability system in every each of products to track down the root cause of deviation, should they happen to occur. All bags carry a unique code number to identifying the root cause of the problem.

To comply all the standard FIBC requirements. We do:

Cyclic Test

Cyclic Top lift test requires the filled bag to be hanged from its lift loops on a test rig devices as weight is added from the top. The bulk bag must maintain a total load of 6x SWL for 5 minutes.

Drop Test

The bulk bag is dropped from specified heights based on the testing requirements of the Packing Group.The bulk bag cannot burst or allow product to escape at each bag height.

Topple Test

The FIBC is placed on a platform filled at maximum SWL capacity. The platform is raised and forced to topple over from a specific height. The bulk bag cannot burst or leak.

Based a unique code number

Tear Test

The FIBC is filled to maximum SWL capacity and cut by a knife. The cut must be at least 100 mm long at a 45-degree angle. The tear cannot expand in size more than 25% when a load equal to 2x the SWL is applied for five minutes.

Righting Test

The FIBC is filled to maximum SWL capacity and knocked onto its side, then righted into proper position by only 2 lift loops. The bag and loops should not show any sign of damage once righted.

UN Certified FIBCs are designed specifically to meet the requirements set forth by the United Nations for transporting and storing hazardous materials. Our UN bags are certified by International Materials Testing Institute to make sure that each of our FIBC bag is safe, functional, and up to rigorous international standards.

When it comes to the safe handling of FIBC bulk bags, it's important to be aware of the correct Safe Working Load for your load capacity.
