PP Sheet for Thermoforming – Complete Technical & Application Guide
Polypropylene (PP) sheet is one of the most widely used materials for thermoformed food packaging, including microwaveable trays, takeaway containers, and ready-meal packaging.
Compared with other thermoforming plastics such as PET and PS, PP sheet offers superior heat resistance, chemical stability, and flexibility, making it ideal for packaging that must withstand reheating or hot filling.
This guide explains:
- PP sheet material properties
- Thermoforming processing parameters
- Typical thickness ranges
- Food packaging applications
- How PP compares with PET in thermoforming
What Is PP Sheet for Thermoforming?
PP sheet is a thermoplastic sheet made from polypropylene resin, commonly produced through extrusion and supplied in roll form for thermoforming machines.
