Cardboard box

Folding boxes are industrially prefabricated boxes, which are space-saving supplied in collapsed condition from the manufacturer to the processing companies, there to be unfolded with simple handles or machine to a box.

The design is a foldable box, consisting of a Faltschachtelrumpf ( sides) with side, running parallel to the height connection with attached bottom and top flaps or hinged lid and tuck there.

Most boxes are now glued to the side seam at the factory. The customer must apply in order to unfold this box to be filled a slight pressure on the sides of the folded box.

Cartons meet primarily four functions:

• They protect the goods
• They serve as an advertising medium,
• They guarantee the stackability of the goods and
• They support the identification of the product by printed or pasted plates.

Classification

The classification of the boxes is done depends on the used materials (cardboard / corrugated cardboard ↔ ) or from the scope (primary packaging ↔ transport packaging).

A) carton / cardboard or primary packaging

According to the classification system of the European Carton Makers Association (ECMA ) for packaging in cardboard / cardboard to distinguish six categories of carton types.

B ) corrugated packaging or shipping

According to the classification system of the European Federation of Manufacturers de Carton ondulé ( FEFCO, over the European Association of Wellpapphersteller. ) And European Solid Board Organisation ( ESBO, via the European Organization for solid board. ) - Abbreviated FEFCO ESBO code - are eight categories of carton types distinguished for shipping corrugated packaging.

Measurements

The dimensions are indicated in the order of A x B x H. Partial found instead of the data A, the indication L.

Where:

In this measurement method is the so-called Rillmaß, which is basically be expressed in millimeters ( mm). It is measured on the flat blank of groove center to groove center.

The Rillmaß should not be confused with the inner and outer dimensions of a carton.

Material

Folding boxes are mainly made from cardboard, cardboard or corrugated cardboard. The choice of material depends on the application of the box.

Carton:

• Secondary fibers: Chrome duplex (GD, GD2 ) Chromotriplex (GT1, GT2 )
• Primary Fiber: Chromosulfat ( CS), chromo ( GC1, GC2 )

Corrugated cardboard:

E.g.

• F- wave
• E- wave
• B- wave

Composites (PE or aluminum clad material ) but are also used. Boxes made from plastic ( PET, PP) or tinplate are rather the exception, but come quite before.

Furthermore cartons Fensterhinterklebung (PE and PET partially wrapped in cellophane ) are offered.

History

Types

The folding box is individual in form and function. There are some standard versions, but basically each carton for each product is created.

The Standardfaltschachtel as described in ECMA, has the top ( lid ) and below an insertion with security slots ( in cosmetics can also be top stop Priller ). Most of the tuck from the back can be closed to the front. Except in the cosmetics industry to avoid open edges of the carton, the carton is (FS ) closed from front to back. The dust flaps can be recessed for a filling machine (magazine slots ).

The floor (bottom) still varies much more, it is available with push-in ( opposite or offset ). A bottom plug, which results in a more stable support of the ground is possible. The glued lock bottom or patent floor is one of the Macharten, which ensures quick assembly, as he straightens himself by folded and glued 45 ° angle brackets and you just have to add the content and must close the lid.

One more style is the Maschinenfaltschachtel whose tabs are glued in the filling system up and down. With grit, they are even closed dustproof. So only the Seitennahtklebung is necessary.

Dust tab

The dust tongue is part of a carton.

Your task is to prevent the intrusion of dust and other foreign bodies into the box interior.

In addition, dust flaps serve at Einsteckfaltschachteln for locking the tuck, so that the lid of the box can not be opened. They also prevent the cover flap is not breaking into the carton, as a kind of back pressure.

In Stülpfaltschachteln the dust flaps sit in the four corners of the box. Allen is dust flaps in common that they are no longer visible when box is closed.

Development

The carton is designed on the computer using a CAD program.

Most of the designer has only the " ABH " dimensions or the packaged goods itself as a template. For this he has to select the right material (cardboard or corrugated board). Next it must specify that the customer wants or the results from the templates a style.

To create first white pattern for the customer, the data is sent to a flatbed, with the help of various tools ( cutters, Oszillationsmesser, scoring knife, creasing wheel, etc.), the pattern created. This also small editions and proofs or laminated pattern can be produced.

At the CAD system and the punch tool is created. For an arc classification is applied, which means more benefit with intermediate cuts and gripper margin are classified as an arc.

Production

Folding boxes are made ​​with a punching tool. The production of a folding box to start printing. Here cardboard sheets are inserted and printed on a printing press. Subsequently, the printed sheets are punched erupted intermediate and edge waste and the individual blanks in the blanking station separated and stacked. The outbreak, Depaneling and the stacking can also be done manually. Then, the blanks are placed in a folder gluer and folded and glued there. Finally, the carton is filled and placed on the market.
