          PP strapping, the scientific name polypropylene, is the lighter kind of common plastics. There are many classifications of PP straps, including transparent, translucent and opaque. All transparent PP straps can be recycled and reused, so they are environmentally friendly. Friends who often use the packing machine may have encountered such a situation. After packing, the joint of the PP packing tape breaks. What are the reasons for the joint break?

PP straps

          There are several possible reasons for the fracture of the pp strapping joint:

1. The temperature of the baler is not moderate, usually around 450 degrees Celsius in summer and 600 degrees Celsius in the north;

2. There is too much dirt on the ironing head of the baler, you can use sandpaper to polish off the dirt;

3. Deflection of the ironing head of the baler must be corrected with pliers;

4. The lower bearing of the middle blade of the baler is deformed, and the middle blade needs to be replaced;

5. The operator does not wait for the upper pallet of the baler to return when working, and then moves the goods down;

          Generally, the fracture strength of the bonding point is 75% of the natural fracture, and the natural fracture of the pure new material PP strapping greater than 4.4g/m is less than or equal to 120kg/bar, and the fracture of the bonding point is 94kg/bar. It is recommended to use High-purity PP straps with a thickness of 0.5mm-0.8mm. The straps of this thickness have light specific gravity, strong resistance to fracture, beautiful appearance, and are the most cost-effective.
