var texts = PackagesListView.Items.Cast<Control>()
                .Where(c => ((CheckBox)c.FindControl("PackageCheckBox")).Checked)
                .Select(c => ((Label)c.FindControl("PackageLabel")).Text);

var sb = new StringBuilder();
foreach ( var text in texts)
   sb.AppendLine(text);

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
            }
        }
    }
}

foreach (var item in PackagesListView.Items.Where(i => ((CheckBox)i.FindControl("PackageCheckBox")).Checked))
{
    var label =(Label) item.FindControl("PackageLabel");
    label.Text += " Appended text";
}

Perhaps this will help you? This should go after page load. Also make sure you are not rebinding your listview.
