Material comparison
HIPS vs PP
Both are common in packaging and liners. HIPS is stiff, easy to form and decorate; PP resists chemicals and heat and is microwavable, but is more challenging to form.
HIPS vs PP — side by side
| HIPS | PP | |
|---|---|---|
| Stiffness | Higher | Lower, more flexible |
| Temperature | Lower | Higher (microwave/hot-fill) |
| Chemical resistance | Moderate | Excellent |
| Formability | Very easy | More demanding |
| Typical use | POS, liners, trays, cups | Microwave/hot-fill packaging, living hinges |
Choose HIPS when…
- Easy-forming, stiff, decoratable parts
- POS, liners and general trays
- Lower cost, room-temperature use
Choose PP when…
- Microwave or hot-fill food packaging
- Chemical resistance and living hinges
The verdict: Choose HIPS for stiff, easy-to-form, decoratable packaging and liners; choose PP where heat (microwave/hot-fill) and chemical resistance matter.
