Conitex Sonoco, a manufacturer and distributor of flexible intermediate bulk containers (FIBC) and other packaging products, has announced 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.
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.
