  • 50% to 300% pre-stretch ratio (preset to customer spec, Std 250%; capability up to 400% depending on film type)
  • The angled carriage with very low wrap possibility, the product is properly secured to the pallet, resulting in a pallet that is more stable for transport, and therefore less damage
  • No film threading is required and a Lexan cover eliminates operator’s ability to reach rollers when gate is closed
  • The pneumatically operated cut and wipe-on system automatically cuts and wipes the film onto the load upon cycle end
    • A vertical roller positions the film over the clamp which grabs the film; this ensures longer heat wire life expectancy
