The cereal liner's principal function is preservation. The liner evolved over time from an uncoated, bleached sulfate paper to a more protective waxed glassine paper. Plastic films were introduced in the mid-1970s. These coextruded films provide superior product protection via improved moisture and grease barriers and seal integrity. In 1985 films were made with bidirectional barrier properties to retain product aroma while preventing external contamination (23). Cereal liners can be modified to preserve other product attributes. Phenolic antioxidants can be incorporated into both waxed paper liners and plastic film coex-trusions to minimize oxidative rancidity, which may impart off-flavors to the product (21). Titanium dioxide is generally added to plastic films to provide varying degrees of opacity where transparency is not desired.
