Shortcuts to test stretch film quality
Besides standard methods, we recommend the following methods for every stretch film users to distinguish better film easily
Appearance of stretch film
Before we doing any test, please check if there is any damage or cut at the film edges. Then, check if the film roll surface is smooth. Also, film made of cirgin material reflects brighter beam lights.
Puncture resistant test
Pull out about 1 meter stretch film and grab the two ends horizontally without extension, gradually push down your fist into the film until it breaks.
For the same size fist and pushing speed, the deeeper you can push down your fist without breaks, the better the punture resistance is.
Also you can use a pen or other sharp tools to pick out the best one from various of stretch films of the same specification.
Elongation test / stretch to break test
Elongation and stretch to break percentage are two important parameters of stretch film. Fisrtly, pull out a meter stretch film, secure the outer side and hold tightly the reel with hands.
Secondly, mark two parallel lines vertically on the center of stretch film slightly like the above does. Thirdly, pull out the rel slowly with constant speed unil it breaks. The longer the space of the two lines, the better the film strretch to break percentage.
