Corrugated case quality is a major contributor to smooth efficient running and quality output
.
1. Check your case dimensions to ensure that the products fill the case efficiently and do not bulge,
overfill or underfill the case. It may be necessary to change the case size. This re-sizing of cases can
often result in cost savings by using the right sized case and correct material weight. Consult your
supplier of corrugated material for help to achieve this. A correctly filled case will help the automatic
process by supporting the case body during flap folding and sealing of the top flaps.
2. Ensure that all scores (fold lines) in your cases are as well defined as possible to help with the
automatic folding process. Your corrugated case supplier can help with this by making sure that
correct score and pressure is used for your case requirements.
This is one of the most common causes
of poor case-closing performance
3. C orrugated case weakness is an area that needs quality control. The fluted construction of
corrugated board can be impaired by various factors in the corrugated case manufacturing process .
Points to watch for:
a. That the flutes have not been crushed overall, causing the case to have a ‘soft’ and limp
feeling. This can create poor crispness during machining and also not give your product the
protection it requires.
b. Selective bands of crushing, usually parallel to the case flutes can cause failure lines down the
case and result in poor performance.
c. Flat cases should be stored in dry conditions and on a flat surface. Be careful not to stack
excessive weight on the cases as crushing can result.
4. Check the squareness of the cases . The glue joint where the manufacturer glues the case blanks
together often can present a quality problem by having an inconsistent gap in the glue lap. This
causes the case to be wider at one end than the other or to be twisted from end to end, conditions
which can be a cause of jams and poor output quality.
5. Slots in the case should be as wide as possible so that the case can be automatically folded with a
minimum risk of flap interference.
6. Overlapped or gapped cases can be a result of incorrect flap lengths. This can be easily checked by
folding the case by hand to ensure that flaps meet neatly in the case center.
