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.
