I have to press/print some sentences with this font on the packages. But when I contact mother company, they said the font used is Song typeface. They are from China. When I searched, too many song typeface fonts appeared but they did not match what I am looking for. I need the digital font file because I can't send back packages to China. 

That’s not a regular outline font, but the internal dot matrix grid from a labelling machine. It might not be available outside of the specific machine. 

Maybe you can try Merchant Copy?
