The purpose of this study was to develop a process to develop a multi-material paperboard based laminate carton and membrane. This includes replacing the existing paperboard-polyethylene-foilpolyethylene structure used in the Foldcan. The new structure must meet the current barrier requirement without contaminating the pulp and finished paperboard. Standard requirements of repulpablility for recycled paperboard mills must aslo be met. Research has been conducted to identify all current materials. Potential replacement material for traditional, commonly laminated materials as well as newly developed materials have been studied. A possible new paperboard based lamination which could be easily separated and recycled by all recycled paperboard mills may be successful!. The research concluded that two development paths would be followed. The first path using a material made of flexible glass. This new material is the best candidate for barrier materials but will not be commercially available in the U.S.A. until 1 994. The second path using a material made with metallization. This structure will prove other aspects of a lamination including bond, sealability and machineability. Ultimately the metilization will be replaced with flexible glass. As environmental laws focus more on closed loop recycling as a process to reduce packaging waste, used packaging components will be required to be re-manufactured into new packaging components.
