PP marked polypropylene containers, cups, bowls, trays, straws, etc. Our PP based food packaging products can be heated in the microwave. The heat resistance of PP ranges from -20 degrees Celsius to +110 degrees Celsius. For this reason they can be used for a much wider range of food packaging. They are as suitable for frozen goods as for hot food. They are practical because they are disposable, so you don't have to worry about washing them. They can be stacked on top of each other.
