General guide to retention/containment force,
It is what is required from the film for different weights and types of loads
Retention/containment force is what holds the load together while on the pallet. It also locks the load to the pallet. Stops it from slipping off when in transit.
| Load weight in kgs | 50 < 200 kg | 200<500 kgs | 500< 760 kgs | 760< 1000 kgs |
| Containment /retention force required | 2-5 lbs | 5-7 lbs | 7 < 12 lbs | 12-20 lbs |
| Load types
examples |
Paper towels empty PET bottles & containers | Stable Regular cartons | Heavy unstable Bags of sugar. Filled paper sacks | Very Heavy & unstable. All liquids and plastic sacks |
| Examples |  |

The ideal wrapped pallet should be wrapped with 4 different levels of tension
Only our Alpha 508 has these exclusive features along with a 300% fixed stretch.
| Tension 1.
Tight. locks load to pallet |
Roping device.
Secures film to pallet & keeps it clear of fork lift |
Tension 2. Varies.
Containment force to suit load without damaging cartons |
Tension 3.
Holds loads together @ top of the pallet |
Tension 4
Pulls load together as it descends. Stops it separating. |
