AI Technical Summary

Technical Problem

Existing steel strapping has high tensile strength, resulting in poor flexibility, making it difficult to adapt to complex packaging shapes and frequent operations. In addition, its production cost is high, making it unsuitable for light industry.

Method used

The steel strapping is made of iron, manganese and aluminum as its main components. A protective film is added and a dense oxide film is formed through a bluing process. Combined with appropriate bluing temperature and time, a packing strap with a tensile strength of more than 700MPa and an elongation of more than 12% at A30mm is prepared.

Benefits of technology

It reduces production costs, improves the flexibility and corrosion resistance of the strapping, is suitable for complex packaging shapes and frequent operations, and extends service life.
