Covered cardboard, being at the same time economic and resistant, allows us to make presentations of great quality and is a material that can be used in the production of folders, binders for catalogues and course booklets, displays, game boards, calendars, book spines, filing boxes, sample books, briefcases, covers, etc.

Cardboard allows to utterly reflect the image of your company by printing it on a paper support with offset or silkscreen quality.

At the same time we can use binding materials such as fabric, paper, polyurethanes, etc.

The personalization of these products is carried out through the most modern technology that the market offers nowadays, being Soldaplastic a reference company in the covered cardboard article production.

The base of these articles is basically made up of lining (outer paper), flyleaves (inner paper) and cardboard.

Both the lining and the flyleaves can be provided by the client, or Soldaplasticcan handle the impression of these materials.

The paper can be plasticized in bright polypropylene or be plasticized in mate, gofrados, PVC, acetates, varnishes… The reason for which a paper is varnished or covered with film is to protect the impression and to increase the durability of the product.

As far as the cardboard, the one that is used the most is the gray cardboard, existing several thicknesses from which to choose. These different thicknesses are denominated “caliber”, being the most common 1´50, 1´75, 2, 2´25, 2' 5 and 3mm.

For the covering process both the outer paper (lining) as the interior (flyleaves) need to have determined weights. For the lining the suitable weight is 135 grams, although we can work with papers between 125 and 150 grams. As far as the flyleaves, its usual weight is of 110 grams, although one can work with products from 100 or 140 grams.

The polypropylene is a thermoplastic material that perfectly adapts to the needs of the graphical market. Thanks to its great versatility and flexibility, it is used for manufacturing all types of folders, packaging and promotional material.

LThe great advantage that offers polypropylene is that of being a material that can be transformed through different processes, it can be printed in silkscreen and offset printing processes, it can be marked, folded, coined, welded, sawed, etc.

This material allows numerous finishes, according to its 4 characteristics: thickness, colour, transparency and texture.

As far as the thickness, the used microns more are: 300, 500, 800 and 1200 microns.

We can find an ample range of colours in polypropylene in its 2 more common variants: opaque and translucent.

PVC plastic offers a great variety of colours and textures that make this material an ideal element to create a multitude array of supports for documentation and filing.

Its flexibility and good resistance makes it recommendable for all kinds of uses as well as the possibility of personalisation through offset impression and silkscreen printing, dry and thermic engraving, etc.

This material comes in different thicknesses measured by microns.

One can find transparent and opaque plastic. Within the transparent plastics the most used thicknesses are 100, 150, 200 and 250 microns; and within the opaque plastics the most used ones are the 300 microns plastics.

The colourless transparent plastic is called “crystal”, coloured transparent plastic is called “coloured crystal”, being the standard hues blue, red, green and yellow, though they are being used less nowadays.

Within crystal plastic one can also find different finishes, such as: bright crystal, matt or gofrado.

Within the opaque plastics there is a great variety of colours and textures, finding within this category the denominated espumados (“foam”), whose thickness is between 1,100 and 1,200 microns, being used mainly for the manufacturing of folders of great quality.

PVC can also be printed with offset quality, always on a surface of a minimum thickness of 350 microns and in “print” plastic quality. This plastic receives a treatment called corona (“crown”) so that the inks can attach on their surface.
