The Conitex Sonoco USA, Inc. flexible products division, BulkSak, has launched a new, multi-layer barrier bag product line.

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 25-kg (55-lb.) size.

The new barrier bag provides puncture-resistant packaging that protects against 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, vice president of the 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 customers 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.
