Why are machine-grade straps more expensive than hand-grade straps?

High dimensional accuracy:The precision requirements for width, thickness, and other dimensions of machine belts are high, and they can generally be controlled within a small tolerance range to ensure good matching with the strapping machine and achieve smooth operations such as feeding, tightening, and welding. In contrast, the dimensional accuracy of manually used strapping may be relatively low, which can affect the packaging effect and efficiency.

High quality raw materials:In order to meet the requirements of high-speed operation and degree packaging of machines, machine belts usually use higher quality raw materials with higher purity and fewer impurities, which helps to improve the physical properties of the packaging belt. Taking PP machine strapping as an example, high-purity polypropylene resin is used to give the strapping higher tensile strength and tear resistance.

Smooth surface:The surface of the machine belt is usually smoother, which is beneficial for smooth transportation in the packaging machine and reduces the occurrence of problems such as jamming and slipping. At the same time, a smooth surface can also avoid scratching the surface of the packaged material during the process, improving the overall quality of the packaging.

High packaging efficiency:The machine strap is specifically designed to be used in conjunction with a packaging machine, enabling fast and efficient packaging operations and improving production efficiency. For example, on large production lines, machine straps can be packaged dozens of times per minute using automatic packaging machines, while the packaging speed of manual straps is much lower than that of machine straps.
