METAL TRAY PACK
a. When inspecting traycans for closed package defects, wipe the cans
thoroughly with a cloth to remove dirt and debris that could hide corrosion defects such
as gray spots. Turn the can under a bright light so that each view (top, bottom, side,
and end) may be closely examined for closed package defects. Examine the tray can
for vacuum defects.
b. Prior to opening the tray can for destructive open package inspection,
completely heat the contents in accordance with the instructions on the can label.
Should a product related defect be identified, record the defect after evaluation of the
heated product to ensure the defect is genuine and not a normal characteristic of the
unheated product. Wash out the can, if possible, and examine the interior for internal

main menu that contains illustrations of defects applicable to the examination of the
exterior condition of filled metal food containers under the US Standards for Condition of
Containers. They are intended for use as references by inspectors, graders, and others
in interpreting and applying the Standards. Since the examination of such containers
under the Standards also includes an examination of the can labels, illustrations of
labeling defects are also included.
DEFINITIONS AND CLASSIFICATIONS OF METAL TRAY PACK DEFECTS
a. Gray Spots. There are two distinct types.
(1) Internal. This type of gray spot is caused by internal corrosive factors. The
corrosion begins when food product comes in contact with the inside surface of the
base material through small breaks or scratches in the inner coating(s). In time, the
corrosion continues through the metal and is observed as a gray to black spot. At this
point, only the external epoxy coating covers the hole and precludes leakage. This form
of corrosion is temperature and time dependent and leakers could result before
expected product shelf life is exceeded.
