Something You Don’t Know About Material Wasting in Pallet Wrapping
When you are wrapping your goods which loaded on pallets, you might think about the best way to save wrapping materials while making a better wrapping and keep your goods safe. Actually, there are somethings you might haven’t known about the pallet stretch wrapping which could avoid the material wasting for you.
- Overstretching:
Stretch film has a certain stretch rate and strength. When wrapping a product with stretch film, the wrapping tightness of the product can be increased through the pre-stretching process, especially when the stretch film tries to restore its original length, which is like a rubber band as we know it. But stretching it too much can destroy its potential elasticity and reduce the stability of the wrap.
Stretch film can only be stretched to “slightly lower” than its marked maximum stretch rate at most, in order to achieve the safest packaging effect and reduce the amount of stretch film.
- Excess stretch film:
Most pallet wrapping machines start from the bottom of the pallet when starting and ending the cycle. This process will easily produce residual stretch film. For companies that use fully automatic packaging lines, it is easy to cause big problems. These remaining parts will cause the machine to get stuck, causing delays in the entire packaging line. You can use manual methods to smooth out the remaining stretch film, but this is a waste of time and may still cause other problems due to human error. The best way is to add an automatic film sweeping function to the pallet wrapping machine.
- Overuse:
We often see many users thinking that as long as they wrap a few more layers of stretch film, they can increase the clamping force of the packaging, but this is not a good method. If it is not packaged with the optimal number of winding turns, wrapping it in multiple layers is just a waste of time and money, and it is also very dangerous. Excessive wrapping makes users think that the clamping force of the packaging can be increased, but the real clamping force actually comes from the correct “stretching” of the stretch film.
The stretching of the stretch film can make the goods become a whole. When the stretch film returns to its original length before being stretched, pulling everything together with the stretch film can reduce the risk of goods moving and reduce unnecessary waste.
- The thickness of the stretch film is too thick:
Don’t be fooled into believing that you need a very thick stretch film to protect your heavier goods. Thickness does not ensure the safety of the goods, only stretchability.
Suppliers want you to use thicker stretch film because it consumes faster and then you will buy more, but if you use thinner stretch film with better stretchability and use it with a good quality pallet stretch wrapper, you can Use less stretch film to achieve better protection.
