This is a disposable drinking cup. It is too thin. It bents with a slight force. Made to hold water and other cold beverages. Single use and dispose afterwards. It is too thin, made of plastic and seems not suitable for hot liquids like coffee and tea.
Is it really not suitable for hot liquids? Think again. Look at the cup bottom. The code symbol number “5”. Code 5 means polypropylene, a polymer resistant to grease, oil and various chemicals. It has high melting point and can be filled with hot foods. Polypropylene is generally recommended for food use.
To test, I prepared enough boiling water and poured it immediately in this disposable cup. The rising water vapor can be seen on picture. No deformities was observed after the test.
Now, can we use this cup for hot coffee or tea. It can be if you can manage to hold the cup without getting burns. However, it can really be used for variety of purposes like a cheap mold for making jelly, maja blanca and duldol.
Reuse if possible because it is a polypropylene. Wash it well and dry.
