Thank you for contacting us.
Please tell us more about the situation where you cannot unzip mlpackage.zip.
Do you mean that you cannot unzip the zip in the first place?
In that case, we can investigate the issue more quickly if you could tell us how you unzipped it (for example, by double-clicking it in macOS Finder) and provide a screenshot of the result.
Or does it mean that the unzipped mlpackage is corrupted in some way?
I would appreciate it if you could let me know.

@CharanPrasadK I just tested now by training a new model in HUB and exporting to CoreML. The download will be a *.zip file that contains your CoreML model. Unzip the zip file to get your CoreML model:
