The best warranties in the industry

4-year unlimited cycle warranty, lifetime warranty on pre-stretch rollers and 10 years on the steel structure and ring gear.

Angled carriage with very low wrap possibility

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.

Features & Capabilities

AC variable frequency drives as standard equipment on all machinesWulftec was the first in North America to do so, for lower maintenance and better reliability. Wulftec stretch wrappers will save time and money.
NEMA 4/12 control panelDust tight and waterproof.
Neatly organized control panelEliminates time otherwise lost searching for wires.
UL508A approved control panel
Superior electrical/electronic designIncludes Allen Bradley Micro800 Series and AC drives.
Quick disconnect cablesOn all motors, proximity sensors, photoeyes and other sensors, simplifying installation and maintenance.
Heavy-duty steel structuresFor rugged performance, even in the harshest work environments. They are built to last forever.
25″ ring gear with pinion gear driveProvides the strongest drive in the industry and is warranted for 10 years.
Dual chain drivenFor balanced movement and no vibration.
“Maintenance Free” spring-loaded carriage gateSpring-loaded rollers ensure optimal contact with the stretch film year after year, without involving maintenance.
Lifetime warranty on the pre-stretch rollers’ blue compoundWulftec is the only manufacturer to offer it.
50% to 300% pre-stretch ratioPreset to customer spec, standard 200%; capability up to 400% depending on film type.
No film threading requiredA Lexan cover eliminates the operator’s ability to reach the rollers when the gate is closed.
Revolutionary drop away clampEnsures clean film release from the pallet load.
Splash proof program with the top cover pause
Non-proprietary partsAccessible on a local base.

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, ensuring longer heat wire life expectancy. The heat wire then 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.
