Conitex Sonoco USA, Inc., a manufacturer and distributor of flexible intermediate bulk containers (FIBC) and other innovative packaging products, announces a new multi-layer barrier bag product line from their Flexible Products Division, BulkSak®.

Offered in 20 to 50 kg bag sizes, the high-quality, multi-layer barrier film bag provides up to 10-color customizable packaging and comes in a standard 25kg (55lb) size. The construction of the barrier bag provides puncture-resistant packaging against corrosive damage caused by humidity, moisture, oxygen, salt spray, aromas, grease, and other airborne contaminants. In addition, an optional one-way degassing valve exhausts air from inside the bag to preserve freshness and maintain quality for products sensitive to oxygen.

“We see an opportunity to offer a competitive advantage to our customers and prospects with this new multi-layer barrier bag.” Says David Monteith, VP Flexible Products Division at Conitex Sonoco. “When there is no compromise for quality, these barrier bags provide a means to maintain a brand’s promise to their customer for a quality, delivered product.”

This alternative to the multi-wall paper bag, offers a variety of customizable laminated film layers. Composite materials available for laminated coextrusion include high-density polyethylene (HDPE), polyethylene terephthalate (PET), aluminum (AL), nylon (PA), ethylene vinyl alcohol (EVOH), and others available upon request.
