Looking to automate with a stretch wrapper?
All applications are different and all stretch films perform differently. Fixed pre-stretch machines do well in most applications and deliver a consistent wrap throughout the pallet. In some cases, you may require an automatic adjustment to the level of stretch and tension being applied to the load. Whether you need less stretch on top or more tension on the bottom, this is where you would benefit from using a variable pre-stretch machine.
In the following video, Ben Dressler, BGR's Director of Equipment, Service and Parts, explains the difference between fixed and variable pre-stretch by comparing a Wulftec SMHPA-200 High Profile Stretch Wrapper and Robopac's Roboplat 708 Stretch Wrapper.
