A static charge is a very efficient way to temporarily bond two materials. When this process is controlled it can be extremely beneficial. When it is an unwanted by-product it can cause all sorts of problems.
If a static charge is present during wrapping then there are a range of issues that can occur. The film can bond to itself or the machine, refuse to leave the reel or even wrap around rollers.
- If the film sticks to the product, this can be prevented by installing a 1250-S Bar in the position shown above, preferably the last place where the film is in free air before wrapping the product.
- If the unwinding film will not leave the reel, or wraps around rollers it should be neutralised with a 3024L Bar just after the unwind.
- If large reels are used then a NEOS 12L will provide excellent medium range neutralisation at distances up to 600mm
- The same principles apply to Over-Wrappers, Flow-Wrappers & Shrink-Wrappers.
