It is required to check the goods we receive from the supplier but unfortunately not everyone who deals with the stretch film products or pallet wrap is lucky to have a proper equipment to do that.
In this case checking manually could be an option, though the result would not be seen precisely, but still it can be used as a guidance.
This is one of the simple ways to check the stretch level manually – we need two people to do this test.
- Hold the roll and loosely pull the film for 10cm length, equals to 100% stretch (This is just for an example).
- Put a ruler or any similar stuffs on the loose film and mark it with a pen marker like the above picture.
- Pull the film out to the maximum stretch. The 10 cm mark should be stretched out, then measure it for the second time with a ruler.
- Now, you would be able to see the stretch difference. It is stretched from 10 cm length (100% stretch) to 37 cm length, (equals to 270% stretch).
