Polypropylene (PP) rigid film is a high-performance thermoplastic material widely used in the thermoforming industry due to its excellent balance of mechanical strength, heat resistance, chemical stability, and cost-effectiveness. It's particularly suitable for applications requiring durability, clarity, and lightweight properties.

Characteristics of PP Rigid Film for Thermoforming

Property | Description

Material Type Polypropylene 
Thickness Range 0.18 mm – 1.8 mm (commonly 0.4–1.5 mm for thermoforming)
Clarity Clear to translucent (can be matte or glossy finish)
Heat Resistance Up to 100–130°C (suitable for hot-fill and microwave applications) 
Mechanical Strength High stiffness and impact resistance (especially at low temps)
Chemical Resistance Resistant to acids, bases, oils, and many solvents
Lightweight Lower density than PET or PS – ideal for reducing shipping costs
