| [PackRequest](/engine/6000.0/script-reference/unityeditor/packagemanager/requests/packrequest.md) | A [PackRequest](/engine/6000.0/script-reference/unityeditor/packagemanager/requests/packrequest.md) instance, which you can use to get the [PackOperationResult](/engine/6000.0/script-reference/unityeditor/packagemanager/packoperationresult.md) representing the path of the generated tarball from the `PackRequest.Result` property. |

### Remarks

`Pack()` is an asynchronous operation. Before the operation is complete, you can use the `PackRequest` instance to monitor the asynchronous operation.

**Note:** Make sure any other Client operations have completed before calling this method. For more information, see the note on the [Client](/engine/6000.0/script-reference/unityeditor/packagemanager/client.md) class reference page.
