Around 1990, kellogg co. Rice krispies treats squares were transformed from a cerealbox recipe into a sweet retail option for snackers. Until recently, these snacks were packaged using conventional coldseal technology, which involved laminating a reverseprinted oriented polypropylene clear film to a metallized opp web.
However, since kellogg switched to a lamination of metallized opp and clear polyester films that are packaged using a heatseal process, the company is enjoying notable benefits relating to sustainability and productivity.
