Belt straps is generally divided into three kinds: PET strapping, PP strapping and Steel strip.The following is to analyze the differences between the three packing tapes in all aspects.
First, material.
It can be seen from the name of the three kinds of raw materials with packaging that determines their differences.
PET strapping | PP strapping | Steel strip | |
Material | polyester resin | polypropylene | carbon steel |
Appearance | transparent,can't tear by hand | opaque,can be torn by hand | opaque,can't be tear by hand |
Second, product performance.
Three kinds of packing tapes behave differently in the same environment: the impact resistance and repeated bending performance of PET strapping are relatively strong, and PP strapping is relatively weak.
products/performance | PET strapping | PP strapping | Steel strip |
Breaking strength | strong | strong | strong |
Shock resistance | strong | medium | medium |
Repetitive bending performance | strong | weak | medium |
Ability to maintain tensioning | strong | weak | weak |
whether or not the bundled objects be contaminated
|
/ |
YES |
/ |
whether or not the bag be tied up | NO | NO | YES |
Long-term stability after bundling the bag | strong | medium | weak |
Long-term stability, solid | After rusting, easy to break | Easy to loose, and bale off |
Third, the use of cost and safety
PET strapping is environment-friendly and green strapping, which can be recycled and is suitable for sustainable development.The PP strapping is not environment-friendly strapping.The use of PET strapping is more secure than steel strapping.
Performance/products | PET strap | steel strip | PP strapping | |
Cost of Use （such as 16*0.6） | low （75 m/kg） | high （13 m/kg） | / | |
environmenttal protection | green，recyclable | limited post-export of the strip packaging | non-green product | |
security | Is it easy to hurt people when cut? | / | YES | / |
not easy | easy | not easy | ||
Compatibility with the outside world | temperature resistance | strong | strong | strong |
chemical resistance | strong | strong | strong | |
Moisture resistance | strong （not easy to rust） | strong （easy to rust） | strong （not easy to rust） | |
Fourth，application.
Pet strap is suitable for large, heavy material packaging，such as：glass, steel, stone, bricks, etc., and is more suitable for long-distance transport. However, the PP strapping is suitable for carton packaging or packaging of other lighter objects. Steel strip is suitable for auto parts, oil drums and so on.
