PET strapping

Now many brick manufacturers everywhere have adopted the non-pallet brick packaging method. The brick bundling packaging has extremely high requirements for PET strapping. Because the edges of the bricks are sharp and the surface is uneven, the PET strapping will contact the surface or edges of the bricks during the packaging process. Contact friction can easily cause longitudinal cracks of the PET strapping, which will cause the longitudinal tension to decrease and the straps to break loose. How to test the resistance to cracking ability of PET strapping?

The test method is to take a random sample of each piece of PET strapping with a length of 2 meters, and use clamps to fold and entrain the strap on the sample. Each pinch point is 20 cm apart to observe whether the strapping has serious brittle points or cracks. The brittleness of the strapping is an obvious feature of poor quality. General plastic strapping will be easy to crack in the longitudinal direction, but good PET strapping can withstand repeated double folding or tear resistance.

The average length of each piece of PET strapping bricks is 4 meters. If the strapping is obviously bent, it means that the strapping is unevenly broken during the tightening process or the machine jamming occurs during the threading process. The test method is very simple, only 5 straps are randomly selected, each of which is about 5 meters in length

The above is the introduction of the test method for the tear resistance of the PET strapping. I hope it will be helpful to you.
