Featured Case Study: Stressed Bags
Bulk Lift’s Response to Stressed Bags Results in Stronger, More Resistant Bulk Bag Solution
Situation
Customers shared concerns within the industry of material failures in the supply chain. Their products, which were contained in bulk bags, were sometimes exposed to higher temperatures, prolonged UV exposure, and increased weight during the filling process. As a result, the bags became stressed resulting in material failures.
Solution
Upon hearing concerns, the team at Bulk Lift International Inc. went to work to construct a bag that could withstand higher stress components, such as high temperature exposure. The answer was to develop a bag loop with a higher strength fabric than the traditional Polypropylene (PP). A prototype was created using Polyester (PET) webbing and then tested for resistance to higher temperatures. See test results provided below:
PET Weight Test: Peak Load 6,227 LB
PET after 150°C: Peak Load 5,766 LB (PP after 150°C: peak load 2,912 LB)
Results
The team manufactured a bag that can retain its strength when subjected to prolonged UV exposure or higher temperatures compared to the standard PP looped bags which has a peak load of 2,912 lbs after 150°C exposure. In addition, a blue line was added to differentiate the stress-resistant bag from others bags within the supply chain. Customers are beginning to show interest in this solution to alleviate any concerns from their customers and internal controls.
New Design concepts plus material solutions lead to our Right Bag On TimeTM promise. It’s part of the Bulk Lift International customer experience.
