Why are machine-use pet straps of higher quality than hand-use pet straps?

1.Production process and precision

(1)Advanced production equipment: Machine strapping band are usually produced through highly automated professional equipment, and parameters such as temperature, pressure, and stretching during the production process can be more accurately controlled, resulting in more stable product quality and smaller differences between batches. For example, in the production of PET machine strapping, the machine can precisely control the extrusion temperature and stretching speed to make the molecular structure of the strapping more uniform, thereby improving its strength and toughness.

(2)High dimensional accuracy: Machine strapping band require high precision in width, thickness, and other dimensions, and can generally be controlled within a small tolerance range to ensure good matching with the strapping machine, achieving 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.

2.Materials and Properties

(1)High quality raw materials: In order to meet the requirements of high-speed operation and packaging, machine band 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.

(2)Better performance: Machine straps typically perform better than manual strapping in terms of strength, toughness, wear resistance, and other aspects. It can withstand greater tensile force, is less prone to breakage during high-speed travel, and has good flexibility, less prone to brittle cracking, and can adapt to different environments and packaging needs. For example, in the logistics industry, machine straps are commonly used to tie heavy goods and require high tensile and impact resistance to ensure the safety of the goods during transportation.
