FACILATATING THE TRANSITION TO POLYETHYLENE (PE) "DESIGN FOR RECYCLE" PACKAGING.
Salted snacks, confections, salad mixes, and condiments are examples of products that are often packaged on VFFS (vertical form fill seal) machines. Compared to alternative packaging equipment, VFFS machines bring value as they minimize floor space and work well for loose, granulated, doughy, or difficult to handle materials that can offer material conveyance challenges.
When choosing the materials for packaging product on VFFS as well as alternative packaging equipment, there is often a balance between providing sufficient product protection, machinability, and cost. At the present time, many of the packaging materials are comprised of multi-materials where each layer of the package is optimized for certain performance characteristics. The benefit of the multi-material composition is that one can take advantage of the synergies of each material component. However, the major disadvantage is that often these multimaterial laminates offer no end-of-life option and are destined for the landfill.
