Product Update: Barrier FOILS
These layers of foils block out oxygen and moisture.
A manufacturer offers liners made with an impermeable layer of aluminum foil. IBC liners are designed to help ensure long-term product integrity. They protect sensitive products, using such additional materials as nylon, Surlyn, and EVOH. The liners act as a barrier against oxygen and moisture. The manufacturer also features vertical fill spouts on its foil liners. These vertical spouts are designed to be easier to fill, and later to reseal, than angled fill spouts. Custom-sized bags are available. CDF Corp., Plymouth, MA; 508/747-5858; www.cdf1.com.
