Main description of PET strap production line :
PET pet packaging belt production line features:
1. Better tensile strength-----PET strap production line has the tensile strength of steel belt, good ductility and better impact resistance. Not easy to break, can ensure the safety of product transportation.
2. Small extension-----Although PET strap is a plastic, its extension change is very small, its elongation is only 1/6 of polypropylene, it can maintain tension, and after packaging, the expansion will no longer change.
3. Strong temperature resistance----Experiments have shown that the melting point of PET packaging belt is around 260℃, and it can be used under 120℃ for a long time without distortion, and it has good stability.
4. Good economic benefits----The density of PET packaging tape is 1.30 ~ 1.38g/cm3, which is only 1/6 of the density of steel tape (7.8g/cm3), equivalent to the length of 6 tons of steel tape, and the price of the same unit length is relatively low.
5. Environmental protection----Steel tape will rust due to exposure to air, and the permeability of rust to packaging is high. PET packaging tape is beautiful and will not rust, but it can avoid unnecessary worries. It can also be recycled.

Application of PET strap
PET packing straps are widely used as a high-performance alternative to steel straps in international packing applications. They offer excellent tensile strength, flexibility, and a low elongation rate, along with superior heat resistance, anti-rust properties, and cost efficiency.
These straps are ideal for bundling a variety of materials, including glass, steel, stone, construction materials, chemical fibers, paper, tobacco, and agricultural products, making them a versatile solution across multiple industries.
