The quality of iron sheet strapping depends on these points. Nowadays, just like packaging cardboard boxes, strapping goods are usually done with strapping steel straps. However, the quality of strapping steel straps on the market varies. How to judge the quality of good products is very important.
1. The purity of polypropylene, the higher the purity of polypropylene, the better the tensile strength of the packaged steel strip.
The quality of packaged steel strips is not only determined by their width and thickness, but also by their raw materials to a greater extent. This is why the price of fully active packaged steel strips remains high. A high-quality packaging steel strip is produced using good materials.
3. The tensile strength is determined by the width and thickness of the packaged steel strip. Even if the packaged steel strip has the same width and thickness, the quality is not the same, which depends on the material of the packaging.
4. After uniaxial excessive stretching, the high orientation of the macromolecules along the axial direction will increase the strength of the polypropylene sheet. Horizontal macromolecules lose their binding force and are more prone to tearing into ribbons, known as tear films, commonly used for tying.
