Converting of Polymer Packaging (Composite Packaging)

Converting means upgrading of a packaging material. A monolayer web (single layer) can be converted to a multilayer composite through a suitable procedure to get better performance. Better performance means better mechanical properties like sealing or puncture strength. It may also mean better barrier properties against light, oxygen, moisture, or aroma or better ESCR (environmental stress crack resistance). Converting may also fulfill marketing aspects like an attractive surface through special printing, lacquering, or a soft touch.
