New box liner film stretches material usage
June 15, 2011
Makers of boxed cereal, baking mixes and other moisture-sensitive dry foods can now downgauge their liner film by 30% or more with new FeatherWeight films from Bemis.
The liner film allows the most downgauging on the market while maintaining machinability, stiffness and strength at gauges as low as 1.5 mil. The high-clarity, high-density polyethylene-based films offer moisture and oxygen barrier to protect food quality and extend shelf life.
FeatherWeight films achieve physical properties at lower gauges through a combination of engineered resins, proprietary sealant technology and Bemis’s tightly controlled manufacturing processes. Seal strength and ease of opening can be tailored to the application, allowing easy opening for consumer convenience or weld seals for tamper resistance.
While designed for box liners, FeatherWeight films may also be used as a sealant layer in printed/converted laminations for any package requiring a moisture barrier. FeatherWeight films need less material to protect dry foods, resulting in less energy to produce and fewer truckloads to ship. Other cost advantages include a lower price per square unit than traditional liner films and more footage per roll, which translates to fewer roll changes for greater productivity.
