These packages are most likely created by the 6.x HPCMS product.
Obtain their guids and then add them into the ItemToDelete table.
If these packages share a common name, you could use the following query to obtain their guids instead of right-clicking each one and choosing properties:
SELECT Guid, GETDATE()
FROM RM_ResourceSoftware_Package
WHERE name like '%common name goes here%'
If they dont exist in that table, try the SWDPackage one.
You could then use a query like this to add them into the ItemToDelete table:
INSERT INTO ItemToDelete
SELECT Guid, GETDATE()
FROM RM_ResourceSoftware_Package
WHERE name like '%common name goes here%'
