How to choose a stretch wrap by type of cargo ➤ ...
The biggest cost driver in stretch wrapping is in-transit damage incurred by loads that were stretch wrapped ineffectively. One of the best ways to stretch wrap well is with a stretch wrapping machine. In fact, weve talked about some of the problems with hand wrapping pallets before, and often the biggest issue with hand wrapping is that machines are just better at wrapping loads than people are.
However, as much as machines are capable, theyre not as smart as you. They cant decide:
WHETHER YOUR FAVORITE FILM WILL WORK.
More than likely, film used for hand wrapping wont work as well on a machine. Youve got to consider the gauge, pre-stretch, and material of the film. Talk with a distributor in your area, who knows as much about machines as he does film.
HOW TIGHT TO STRETCH WRAP YOUR LOAD.
The top, middle, and bottom layers of your load need to all have the correct amount of containment force, which is the film tension multiplied by the number of film layers. Containment force is what holds the load together. The right amount of containment force depends on the type of load youre wrapping. Is your load heavy, light, or unstable? Heavy loads may require more containment force and light loads may require less.

WHY THE FILM JUST BROKE.
The way the load is wrapped depends on your stretch wrappers settings. You need to choose the number of top and bottom wrap counts. You must also decide the wrap force settings and how much overwrap you want applied on top of the load as well film delivery systems speed and the rotation speed of the turn table or wrap arm.
- Keep your products from overhanging the pallet and try to eliminate sharp corners.
- Train operators to properly handle film. Improper film threading is a main cause of film breaks. Film breaks can occur when the film roll experiences nicks. These nicks happen when the film roll has been dropped or mishandled.
- Dont set the wrap force too high. Depending on your film and product, adjust the tension of the film to determine the best setting.
If the load needs special attention or reinforcement at some spot.
You may need to secure partial layers with the roping technique or you may need to band apply multiple layers of film to one spot on the load.
STRETCH WRAPPING MACHINES GIVING THE BEST OF BOTH WORLDS
Stretch wrapping machines have the potential to greatly increase a pallet loads chances of arriving in as made condition. They simply do a better job than people at consistently wrapping loads to wrap standards. However, human beings do have a place in the stretch wrapping process. With a bit of research and practice people can work with their stretch wrapping machines to make sure their loads have the best chance of reaching their destination in as made condition.
Make sure the machine you buy will get the job done. A good rule of thumb is always not to guess, but to test. Get help if youre not sure.
