c. Secure the desiccant by tying, taping, etc. or in specially
designed desiccant baskets affixed to the container interior
(some desiccants are supplied in self adhesion
packs).
d. Secure the desiccant adequately to prevent it from shifting,
moving and preventing it in all circumstances from
coming into direct contact with critical surfaces of the
enclosed item.
e. Removing the desiccant and inserting it into the unit
pack shall be the last action before final sealing of the
bag or container.
f. Once desiccant is applied and the bag or container is
sealed/closed, place a Method 50 label on the outer surface
to indicate that a desiccant is placed inside (see
Figure 5-4 and Figure 5-5).
5.21 CUSHIONING.
MIL-STD-2073-1 states that shock and vibration absorption
shall be provided by cushioning materials or devices that adequately
protect the contents and packaging components from
physical damage during handling, shipment, and storage.
Cushioning shall be placed as close to the contents as practicable.
A non-corrosive wrap shall be placed between the item
and all corrosive type cushioning media.
5.21.1 Purpose. The purpose of cushioning is the protection
of an item from physical and mechanical damage afforded
an item by means of compressible and resilient material
designed to absorb the energy of shocks and vibration caused
by external forces.
5.21.2 MIL-HDBK-304. To better understand the characteristics
and functions of cushioning materials and how they
function, refer to MIL-HDBK-304, Package Cushioning
Design.
5.22 METHODS OF CUSHIONING.
Cushioning is usually accomplished by any of four methods or
a combination thereof. They are known as floated item, floated
pack, corner pads and side pads, and shock mounts.
Figure 5-4. Method 50 Label
5.22.1 Floated Items. The item is floated in non-corrosive
and low moisture content cushioning material and placed
within a unit container. This is perhaps the method most commonly
used for cushioning small, lightweight, fragile items
against shock, vibration, and abrasion. Since a container may
be dropped on any one of its faces, edges or corners, the
cushioning material is designed to withstand the full impact of
the entire weight of the item in any direction (see Figure 5-6).
5.22.2 Floated Pack. The item is packed in an interior container
which in turn is floated in cushioning material. This
method is generally used in connection with semi-fragile items
of medium size and weight. The item is initially packed in an
interior container, then floated in cushioning, and placed into
an exterior container. Since the materials will not come in
contact with the item the non-corrosiveness and moisture content
of the cushioning materials is not critical (see Figure 5-7).
5.22.3 Corner Pads/Blocks and Side Pads. Corner pad/
blocks are used where a minimum amount of material is
required to cushion the item and a full floated item or pack is
not justified because of the weight and size or fragility of the
item. They are also used where the only requirement of the
cushioning is separation of the item from the container. If the
amount of cushioning material is too great for corner pads,
then side pads may be used.
