    • upgrade the base at any time
    • upgrade the carriage at any time
    • change the tower/wrap height at any time
  • Wulftec was the first in North America to put AC variable frequency drives as standard equipment on all machines. Why? Lower maintenance and better reliability—Wulftec stretch wrappers will save time and money
  • NEMA 4/12 control panel dust tight and waterproof
  • The control panel is neatly organized eliminating time otherwise lost searching for wires
  • The control panel is UL508A approved

  • A 25″ ring gear with pinion gear drive provides the strongest drive in the industry and is warranteed for 10 years.
  • Dual chain driven for balanced movement & no vibration
  • Quick and easy adjustment of upper and lower carriage travel
  • The “Maintenance Free” spring loaded carriage gate equipped with spring loaded rollers, ensures optimal contact with the stretch film year after year, without involving maintenance

  • Since all of our semi-automatic SMART Series™ stretch wrappers wrap 2 inches from the turntable, you are guaranteeing 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
    • Then the heat wire swings in and cuts the film
    • A timed impulse heat control, allows quick cool down so the heat wire becomes cold to the touch within 5 seconds
  • Wulftec’s revolutionary drop away clamp ensures clean film release from the pallet load
  • Benefit from our splash proof program with the top cover pause
