PP vs PET Strapping Production Line: Key Differences Explained

December 25, 2025

Strapping tape is widely used in logistics, construction, packaging, and heavy industry.

Among all materials, PP (Polypropylene) and PET (Polyester) strapping are the most common options — but their production lines, performance, and target markets differ significantly.

Understanding these differences is essential when selecting the right strapping production line for your factory.

PP vs PET Strapping Production Line: Key Differences Explained

1. Raw Materials and Processing Differences

PP Strapping Production Line

● Raw material: Polypropylene (PP)

● Lower melting temperature

● Easier extrusion and forming process

● Lower equipment investment

PET Strapping Production Line

● Raw material: Polyester (PET flakes or pellets)

● Higher melting temperature

● Requires precise drying, extrusion, and stretching

● Higher technical requirements for machinery

From a machine perspective, PET strapping lines require more advanced extrusion systems, temperature control, and stretching units to ensure stable performance.

2. Strength and Performance Comparison

Yes

PET strapping offers excellent tensile strength and dimensional stability, making it ideal for replacing steel straps in industries such as steel, bricks, timber, and construction materials.

3. Production Line Configuration Differences

PP Strapping Production Line Features

● Single or twin-screw extruder

● Simple stretching system

● Suitable for small to medium output

● Lower power consumption

PET Strapping Production Line Features

● Advanced screw design for PET processing

● Crystallization & drying system

● Multi-stage stretching and annealing

● Precise thickness and width control

A high-quality PET strapping production line directly determines strap strength, surface finish, and consistency.

4. Application Scenarios

PP Strapping

● Carton packaging

● Household appliances

● Light logistics

PET Strapping

● Steel coils

● Cement blocks

 Aluminum and timber

 Heavy palletized goods

Choosing the right strapping material also means choosing the correct production line configuration that matches your target market.

5. How to Choose the Right Strapping Production Line

When selecting between PP and PET strapping lines, consider:

● Target product application

● Required strap strength

● Daily production capacity

●  Available raw materials

● Energy consumption and labor cost

A professional equipment supplier should offer customized line solutions, not just machines.

Conclusion

PP and PET strapping production lines serve different markets and performance requirements.
Investing in the right production line ensures stable quality, high efficiency, and long-term profitability.

If you are planning to produce PP or PET strapping, machine design, process control, and technical support are just as important as raw materials.
