WCRT-200 Automatic Rotary Arm Stretch Wrappers

The WCRT-200 conveyorized fully automatic rotary arm high-speed stretch wrapping system.

Our Automatic stretch wrappers maximize throughput and efficiency. They take care of everything; you only change the roll of film. An automatic stretch wrapper will save significant time and money.

The WCRT-200 can keep up with even the most demanding production rates. It can wrap almost anything. It is ideal for wrapping very light, very heavy, tall or unstable loads and also great in wash-down and dusty applications.

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
Wulftec is the only manufacturer to offer a LIFETIME warranty on its pre-stretch rollers’ blue compound.
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
- 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
Non-Proprietary parts accessible on a local base
The best warranties in the industry
