without film breaks.

Pre-stretch kits, to a maximum of 300%, are available.
Note: With some premium films you can use a higher pre-stretch and hold the film tension without film
breaks.
Caution: An increase in the pre-stretch percentage lowers the film tension and can cause film breaks.
•
Use a higher pre-stretch for light loads that can use lower film tension.
Use a lower pre-stretch for irregular or inboard loads that have frequent film breaks.
