Twinwall Polyproplyene


Twinwall Polypropylene Sheet is a highly versatile material, suitable for a variety of signage, display, packaging and building applications.

Key features of the material are:
    Water resistant
    Lightweight
    Low cost
    Easily fabricated
    Suitable for outdoor use
    Has excellent chemical resistance
    Food safe
    Recyclable
    Reasonable impact resistance
Applications include:
    Packaging
    Signs
    Displays
    Enclosures

Twinwall Polypropylene Sheet is usually cut using conventional paper guillotining equipment. The material can also be die cut or scored into a variety of shapes using standard steel rule die cutting equipment. For smaller job runs or craftwork a sharp utility knife is also suitable.

Twinwall Polypropylene Sheet is ideal for screen printing with most inks formulated for polypropylene. Solvent based and UV inks work exceptionally well, providing superior adhesion. PP Flute can also be printed using both letterpress and flexographic processes. Vinyl graphics can also be easily applied.
