3.5 Sealed packings
Sealed packings are used for delicate components.
In contrast to standard packings, machine parts are completely enveloped in plastic foil wrappings whose
seams are welded to make an air-tight seal. As much of the air as possible inside the foil wrapping is first
removed by suction. The amount of desiccant to be enclosed is calculated for the specified duration of
transport and storage, taking into account the climatic zones involved. All sharp corners and edges are
padded to prevent the wrapping from ripping.
All cases should be subjected to an immediate visual inspection on arrival to make sure the packing, the
contents and the seals are undamaged. If humidity indicators have been provided, the sealed packings must
be inspected visually 1 to 2 days after storage.
IMPORTANT
If cases have been opened in the ports of arrival and the sealed wrappings have been damaged or if
cases have been damaged during transport, the sealed wrappings must be repaired as quickly as possible
(if possible) in order to ensure proper storage, especially in tropical areas. Opening or damage to the
wrappings must berecorded in writing and immediately reported to the project manager/site supervisor.
If humidity indicators are provided in the sealed wrapping, there is an inspection opening in the external
packaging, the cover of which can be unscrewed. Humidity indicators change their colors from blue (dry) to
pink (damp) to indicate the humidity level (relative humidity) within the sealed plastic wrapping.
IMPORTANT
Humidity indicators recondition themselves automatically, i.e. they do not indicate whether the humidity
inside the packing was too high at an earlier time.
