Sack _s pouch or = the like «

The innovation relates to an open sack., Bag or the like «with a wall consisting of several layers., of which the outer layer consists of plastic film and at least one inner layer consists of paper.

The innovation is based on the object to create _s a bag or pouch of this kind, on the one on conventional paper processing -. Or bag or sack machines can be produced and, secondly, improved insulation of the bag contents against temperature fluctuations together with higher resistance capability in Warmgutbefüllung? has "the aim is the sack or bag at the highest possible softness of the wall of the bag contents against the entry of undesirable substances, protect u _o a _o moisture _s and one at dampening the outer layer, for example, due to weather conditions continued high load-bearing capacity of the bag have" Finally, should the bag or bags allow a print with high brilliance to be attached,

For this purpose, the sack or bag according to the innovation, in contrast to, for example, known pocket sacks outer paper layer and a separate plastic inner layer forming an independent sack component markedj that the outer plastic layer with the the paper inner layer adjoining it is connected to a wall unit by means of adhesive before the bag is formed. The adhesive connection is expediently strip-shaped or point-shaped formed and can advantageously form the shape of a fine lattice »

An embodiment of the subject innovation is shown schematically in the drawing _s illustrates a top view of a lay-flat bag illustrated with a cross bottom "The designated as a whole with 1 bag or pouch is provided at its upper end 2 open and for example with a thumb cut-3" Instead of the illustrated cross bottom 4, this can also or the like with a block bottom. Be provided with a bottom and, if necessary, have gussets »

The Helping in the drawing the viewer outer layer 5 of the bag is made of plastic film _s as smooth film with high Brill ^ anz printable or as a transparent film opens up the possibility _s imprints on the next inner adjacent to her paper layer to shine through "When next inner layer a paper layer is provided, which is visible in the illustrated embodiment in the area of the thumb cutout and is designated with β »This

Paper layer 6 is provided with the outer plastic layer 5 glued to ₃ wherein the bonding is configured so that _s a connection between two layers 5 ₃ 6 consists only in limited surface areas. The bonding can be accordingly punctiform ,, wherein the points an arbitrary _s preferably eg "forming a lattice-shaped grid ,, or may be designed in strip form _s the strips advantageously also in the form of a lattice form" In the illustrated embodiment, the strip-shaped Klebverbindungsbereiche in the transverse direction marked with 7 and in the longitudinal direction with 8 "

In the context of the production of such sacks or bags goes the folding of the shape is preceded by the gluing of the individual layers to form a wall or layer unit.

Claims (3)

- 4 protection claims: 1. Open sack _s bag or the like. ₃ with a multiple layers of wall ₉ vender the outer layer of plastic film and at least one inner layer is made of paper ,, characterized _s that the outer plastic layer (5) with its adjacent inner paper layer (6) before the bag formation by means of adhesive is connected to a wall unit. Ο 2 sack or bag according to claim I ₉ characterized _s that the adhesive bond is strip- or point-shaped, 3. bag or pouch according to claim 1 or claim 2 ₅ characterized in that the adhesive bonding _s (7 ₉ 8) forms the shape of a grid.
