STRENGTHEN THE PACKAGING

End-of-line packaging systems are normally installed in most industries. The systems will control a specified
weight or quantity of products. This is the final quality control process before shipping the products to consumers

End-of-line packaging is the final step assured. Moreover, the selection of suitable machines to verify a product quality can reduce

of products might not match the total amount
specified on the package. Or, the packaging
is unfortunately left empty without the products
inside. Or, the products do not reach a weight
standard, for instances.
According to above incidents, there are
numbers of technique of investigation by the
machines at the end of production line before
shipping out, for instances, Checkweigher, or
X-ray machine for auditing a contamination
at end-of-line packaging. Those machines can
sometimes misinterpret in quality control
process. This is called - False Rejection when
unfortunately rejecting good products instead.
False rejection screens out a good
product. To preserve a product quality and to
reduce production cost is to understand how
products are sorting out. Take this as an
example. The products in a carton are 24
piece-count with the total standard weight
range. If one item is missing, the box must be
removed due to a failure in quantitative rule.
On the other hand, a case of packing 24
pieces in a carton with each weight lower than
the standard. The checkweigher captures
irregular weight range. This carton shall be
taken out due to a failure in weight rule even
though this box has a total of 24 pieces. Take
another example. When the vision camera is
installed to check the items in the box, a large
number of qualified products could wrongly
be removed. This could happen when the
products are overlayed, so the camera is
unable to detect. As a result, it causes an
additional time to recheck. Besides, more
manpower is assigned to perform repetitive
tasks at the sorting point. It may also cause
the entire process decelerated. Sometimes,
it requires to tear or destroy the packaging for
validation. This results in a higher cost of
production. All of these consequences are
from false rejection.
The preventive guidelines for false
rejection at end-of-line packaging required a
good control measure through the entire
production process. Then, the quality of
product packaging at the end of line can be
