STRENGTH AND SAFETY – Unlike traditional film liners that are composed of mono-layer film, our liners are made of co-extruded film formulated to yield the highest strength and puncture resistance of any liner on the market. In fact, our humidity barrier film liners are able to stretch up to 880 percent before breaking. This impressive elongation capability provides a significant advantage over woven liners, which are able to stretch only 15 to 30 percent before breaking.

SUPERIOR CONSTRUCTION – BULK-FLOW’s humidity barrier film liners feature a seamless, tubular construction. The lack of seams eliminates the chances of product contamination with loose threads, as well as the possibility for leakage. Our liners are also composed of virgin resin materials for additional protection from contamination.

ULTIMATE PRODUCT PROTECTION – Our HDPE film liners’ proprietary formulation minimizes the transmission of water vapors in order to protect the liners’ contents from moisture damage. In fact, our HDPE film liners are six to eight times more impermeable than woven liners and three to four times more impermeable to humidity than other film liner designs.

ACCESSIBLE DISCHARGE PORT – Blocked discharged ports can be disastrous for a product’s recipient. Our film liners feature a top steel bar with low-elongation hanging belts designed to hold the bulkhead in place so that the discharge port is always exposed and accessible to receivers.

COST-EFFECTIVENESS – Our film liners feature a proprietary flooring system that eliminates the need for a fifth steel bar in the liner’s floor; hence, reducing the overall packaging cost.
