Cardboard

With the introduction of new standards in the packaging field, corrugated cardboard has become the most popular material in the production of packaging.
As opposed to foam and plastic-based materials, it is 100% recyclable and biodegradable.


The facings are made from two sheets of paper stuck together with natural glues deriving from potato or corn flour enclosing the fluted paper that gives it stability and resistance.

As the height of the flute can vary from 1.5 to 5 mm, there are various combinations that bring the final thickness of the board from 1.5 to 15 mm. Besides the thickness, the quality of the paper used and its weight is fundamental to determine a minor or major resistance. One it becomes the finishing packaging, corrugated cardboard becomes a sturdy and versatile packaging, ideal for grouping, transporting and protecting..

Types of corrugated cardboard:

• Single board: just one high or low flute or microflute.
• Triple board: with combined high/low flutes or microflutes.
• Triple wall board: three sheets of fluted paper for specific high resistance uses.

Types of facings used:

• Board treated against moisture.
• Vegetal fiber board: used for packaging food.

Abbreviations

L= liner, paper with good mechanical characteristics produced with one or more layers of fibery material;

T= test, paper with discrete mechanical characteristics, similar to the previous;

KB/LB/TB= white facings;

BP= coated board;

C= chamois, produced exclusively from recycled or poor resistance pulp;

ABBREVIATIONS FOR FLUTES:

S= semi-chemical, paper with quality characteristics containing at least 65% deciduous fiber;

M= average, good characteristics produced with recycled or semi-chemical pulp;

F= fluting, paper with discrete characteristics produced using only recycled pulp.

Gifco-Fefco codes

These codes have been set by FEFCO and ASSCO to be used as a simple, internationally understood coding system in that they are not tied to the knowledge of languages and thereby allow individualising the various types of cardboard packaging without being forced to give a description, which is often long and complicated.

The main packaging groups are identified by the first two figures marked on the packaging.

02 – Cases with flaps or tabs joining or overlapping (either completely or partially), made, more or less, from a single sheet of cardboard.

03 - Telescope cases consisting of at least two pieces, a bottom piece and a lid, which fit into each other to form or close the lid, they are joined at the bottom.

04 - Foldable boxes generally made from a single sheet of cardboard; both sides and lid are joined at the bottom.

05 - Moving boxes consisting of at least two handholes that fit into each other.

06 - Rigid boxes generally consisting of a central part to which the top and bottom must be joined by a successive operation.

07 - Automatically closing cases, generally made from a single sheet of cardboard; they are delivered flat and can be easily erected by the user.
