October 30, 2017 – Gastonia, NC – 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 – 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.” explains 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 superior 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.

As with all their packaging products, Conitex Sonoco offers engineering and technical support. Visit for more information and to download our brochure, or call 1-704-833-1353 to speak with a customer service representative.
