Flip lids on polypropylene containers by Laszlo Lipot
 

Polypropylene (PP)

Polypropylene's resistance to fatigue enables it to be used for flexible (living) hinges. It resists most forms of physical damage including impact and freezing, resistant to corrosion and chemical leaching.

Examples of use: Flip-top bottles, cases and boxes, moulded products, bottles, insulation for electric cables, stationary folders.
