When should plastic strap be used (Polypropylene or Polyester)?
You should use plastic strap if following conditions are implemented:
- Load weight is less than 2 tons.
- Package temperature is less than 100°С / 110°C.
- Package surface is flat or round (min diameter is 50 cm)
- Edges aren't sharp (we don't need protection corners using).
- Required strap breaking strength is less than 4000 N.
Plastic strap types:
- POLYPROPYLENE (PP) (usually with strap breaking strength from 50 till 350 kg)
- POLYESTER (PET) (usually with strap breaking strength from 150 till 1100 kg)
- Nylon (isn't widely used).
Plastic strap advantages comparing with steel strap:
- More chipper than steel strap
- Low costs of delivery
- Less quantity of rolls are required (with the same length)
- High strap tension
- Good resistance to external influence
- Keeps its tension even during load transportation, displacement, shaking or tightening (high flexibility)
- Doesn't bring to goods corners / edges damage; low friction
- Doesn't subject to corrosion, as a result doesn't put rusty spots
- Even tension distribution along the whole strap length
- More safe and foolproof than steel strap
