The most important aspect of wraparound blanks is the
flute direction. This is determined from two main aspects, the load bearing
contribution of the product and the collation in relation to the flaps.
Virtually all wraparound machines work on the same basic
principle of feeding the collated primary products on to the blank and
the flaps are at each side when being transported through the machine.
Please note that confusion often exists in the terminology
concerning length, width and depth of wraparound cases. It is important
that the standard notation of length, width and depth in relation to the
flaps is used irrespective of how the case travels through the machine
or on which face it is stacked.
It can be seen from the proportions of the case it is
an "end loading pack" and is therefore normally stacked on face
It is possible by modifying, the collation and therefore
the case proportions to stack the finished pack on the flaps and it then
appears as a standard RSC case with top and bottom flaps.
When bottles are being packed the collation usually
cannot be changed and have to be upright. The flaps then are at the end
of the case.
