Shipping case design parameters
Shipping Cases -
Secondary Packages - ASTM D5118
R.S.C. - 0201 - The
most common form of shipping container is the Regular Slotted
Container - FEFCO 0201.
Below are some guidelines for the construction of a good R.S.C.
- R.S.C. standard
flaps. Gaps on the top and bottom flaps should
not exceed 1/8" (3mm) when taped. Gapping flap
options should not normally exceed 1/4" (6mm). A
small gap in the flaps is often required for case sealing
machinery. A gapping flap style is sometimes referred to as an 0209
rather than a 0201.
- Manufacturers joint
can be glued, taped or stitched. Gluing is the most
common method and preferred except on very heavy boxes (above
65# - 30Kg). Staples used in stitching must be rust
resistant, and normally no more that 2" (55mm) apart
and no more than 1" (25mm) from the ends of the
joint. Tape used for the manufacture's join should be of sufficient
width and of the reinforced type.
- The manufacturer's joint may
be attached to either length or width panel, but some
case erection machinery can require a particular arrangement of the panels.
- Minimum manufacturer's joint
size that we would recommend is 1" (25mm) with 1.25"
(30mm) being a preferable minimum figure. The joint must be
initially cut not more than 3/16" (5mm) below the
scoreline on the top and bottom of the box. When the
Extended Glue-flap option is chosen, the extended flap
must also be glued to the flaps of the box. The
purpose of glue lap extensions is to strengthen the joint
of a glued case. They are typically used for all single
walled glued cases, particularly those with a depth less
than 1' (305mm)
- Adhesive must be waterproof
upon setting. Bond must extend at least 90% of the length
of the joint and have a minimum of 85% fiber tear.
- Tolerances are +/- 1/8"
(3mm) on all scoring dimensions for boxes >20" (55mm)
sum of L+W+D. Tolerances are +/- 1/16" (1.5mm) for
boxes with L+W+D <20" (55mm).
- Maximum expected board wrap
tolerances should be 2% in the overall net size for
machine erected cases and 4% in the overall net size for
hand erected cases.
- Styles - FEFCOThe European Federation of
Corrugated Board Manufacturers was created in 1952. Its
headquarters are situated in Paris and the Federation is
governed by French Law. Today FEFCO has 20 Active Members

Description of basic type groups
(The terms Box and Case are interchangeable in the context of
02 - Slotted-type boxes consist
of basically one piece with a stitched, taped or glued
manufacturer's joint and top and bottom flaps. They are shipped
flat, ready to use and require closing using the flaps provided.
03 - Telescope-type boxes consist
of more than one piece and are characterized by a lid and/or
bottom telescoping over the body of the box.
04 - Folder-type boxes usually
consist of only one piece of board. The bottom of the box is
hinged to form two or all side walls and the cover. The boxes can
be set up without stitching or taping. Locking tabs, handles,
display panels etc., can be incorporated in the design.
05 - Slide-type boxes consist
of several pieces of liners and sleeves sliding in different
directions into each other. This group also includes outside
sleeves for other cases.
06 - Rigid-type boxes consist
of two separate end pieces and a body and require stitching or a
similar operation before they can be used.
07 - Ready-glued cases consist
of basically one piece, are shipped flat and ready to use by
simple setting up.
09 - Interior fitments such
as inside liners, pads, partitions, dividers, etc.

Case Terminology - A cross-reference section is
provided in order to aid in communication as terminology can vary
even between different groups within the same company. FEFCO
standards are widely use in Europe and have gained some
acceptance in the US; they offer one good way of reducing the
"tower of Baybel" effect.
It is impossible to list all of
the terms used to describe pack designs. Here, however, are
listed some of the terms more frequently used. FEFCO number codes
should be used to describe a case wherever possible to stop any
Some of the FEFCO designs have no
frequently used name, so the most general terms of die-cut tray
or die-cut folder is given. It should be noted that some designs
have names relating to their use. This does not mean these
designs are not frequently used for other purposes.
