Soft Pack

Inner Bundling

Core Description
Inner Bundling (or Liner Packaging)  is designed to serve as the structural backbone of the soft-pack. Because soft-packs lack a rigid outer box, this material provides the necessary tensile strength and stiffness to maintain the cigarette bundle's rectangular integrity during handling and transit.Structural Reinforcement & Hermetic Sealing Offers a higher grammage and stiffness profile to protect cigarettes from physical deformation, combined with ultra-low WVTR to compensate for the less-secure outer paper wrap.
