Wulftec is the only manufacturer to offer a LIFETIME warranty on its pre-stretch roller blue compound
Preset pre-stretch ratios are available from 50-300%
Angled carriage with very low wrap possibility properly secures the product to the pallet, resulting in stable transport and less damage
No film threading required
Lexan cover eliminates operator's ability to reach rollers when gate is closed
Wulftec's revolutionary drop away clamp ensures clean film release from the pallet load
Non-proprietary parts accessible on a local base

Cut and Wipe System

Pneumatically operated cut and wipe-on system automatically cuts and wipes the film onto the load upon cycle end
First a vertical roller positions the film over the clamp which grabs the film, ensuring 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

Best Warranties in the Industry

3-year unlimited cycle warranty
10-year warranty on steel structure
Lifetime warranty on pre-stretch roller blue compound
