PRODUCT PROTECTION – BULK-FLOW’s barless woven HDPE liners have the thickest internal and external lamination of any liner in the industry, providing an impermeable barrier against humidity. BULK-FLOW liners also feature a circular seamless construction, thus eliminating the permeable seams found in many other types of woven liners.

CONTAMINATION-FREE – Because our barless woven liners are seamless, shippers don’t have to worry about loose threads from seams contaminating their product. Likewise, our liners’ thicker-than-average lamination layer ensures strong bonding and eliminates the risk of delamination, which could also lead to product contamination.

SAFETY AND STRENGTH – Our packaging engineers designed the barless woven HDPE liner with safety in mind. Our liners’ fabric is composed of high-quality virgin resins, and our disciplined quality control procedures ensure that all liners are well-designed, safe and secure.

SELF-RESTRAINING – The built-in self-restraining system successfully braces the load without the need for the dangerous and costly steel bars typically included in the design of traditional container liners. These bars are constantly under pressure and can sometimes become dislodged when the container is tilted, which can lead to injury or death. With BULK-FLOW’s patented built-in self-restraining system, you don’t have to worry about these risks. This system has been tested extensively for safety and is capable of withstanding the pressure of up to 41MT of cargo.

FAIL-SAFE/REDUNDANT SAFETY CAPABILITIES – BULK-FLOW’s barless woven liner is the only one in the market with a built-in fail-safe safety system. Although steel bars are not required for our barless woven liner, the liner has sufficient clearance at the door of the container to allow for the addition of optional steel bars for extra safety. The extraordinary strength of the liner’s self-restraining system protects the steel bars from pressure even when the container is tilted. However, should the self-restraining system fail, the steel bars will be in place to prevent an accident.

COST SAVINGS – BULK-FLOW’s barless woven liner provides significant cost savings by eliminating the need for expensive steel bars to brace the container’s load. In most cases, our barless woven liner will eliminate the need for four steel bars. However, in high-density product applications, it can eliminate the need for sourcing, handling and purchasing up to eight steel bars.

FULL CARGO CAPACITY – Other manufacturers’ barless liners are often smaller or shorter in order to reduce bulging. However, BULK-FLOW’s barless woven liner is not reduced in size, allowing shippers to utilize the container’s full capacity.
