Identify Steel Banding Methods

　　Nowadays, steel banding is usually used for bundling goods and carton packing, but the quality of steel banding on the market varies, so how should we distinguish the quality of steel banding? What are the methods? The following editor will introduce it to you in detail.

　　1. After the polypropylene sheet is overstretched uniaxially, the macromolecules are highly oriented along the axial direction, and the strength will increase. The horizontal macromolecules lose their binding force and are more easily torn into ribbons, called tear film, which is widely used in bundling retail goods.

　　2. The tensile strength of the steel banding is determined by the width and thickness of the steel banding. Even steel bandings of the same width and thickness have different qualities, which depends on the packaging material.

　　3. The quality of steel banding is not only determined by width and thickness, but also by its raw materials to a greater extent, which is why the price of fully automatic packing steel belts remains high. A good quality steel banding must be produced with good materials.

　　4. The quality of steel banding depends entirely on the purity of polypropylene. The higher the purity of polypropylene, the better the pulling force of steel banding.

　　The above are the identification methods of steel straps. After mastering these methods, we can easily distinguish them when purchasing in the market.
