You will have to find the checkbox since it’s inside the template field
Example:

if (PackagesListView.Items.Count > 0)
{                
    for (int i = 0; i < PackagesListView.Items.Count; i++)
    {
        CheckBox PackageCheckBox= (CheckBox)PackagesListView.Items[i].FindControl("PackageCheckBox");
        if (PackageCheckBox!= null)
        {
            if (PackageCheckBox.Checked.Equals(true))
            {
                //do your stuff here
            }
        }
    }
}
