A good way to mention your address or name on plastic. 

Just heat the form (but not too much) and apply a gentle pressure, equilibrated on all length.

The reason I build this is linked to a newly purchased container for rubbish (paper, plastic), as I  have heard that it happens to disappear in some cities. 

For long names, I recommend to split them in shorter parts.

Don't forget to test first on a hidden zone.
