(FR) PROCEDE DE FABRICATION D'UN SAC EN PAPIER ET SAC EN PAPIER
Abstract
(DE)
Bei einem Verfahren zur Herstellung eines mehrlagigen, teilweise luftdurchlässigen Papiersacks, welcher zumindest zwischen zwei Papierlagen (3, 8) eine insbesondere aus einer Kunststoffolie bzw. -beschichtung bestehende Zwischenlage (4) aufweist, wobei wenigstens die Zwischenlage (4) und eine damit verbundene bzw. verbindbare Papierlage (3) mit einer Mehrzahl von Perforationen bzw. Durchbrechungen (13) ausgebildet wird, wird vorgeschlagen, dass die Durchbrechungen (13) ausgehend von der mit der Zwischenlage (4) verbundenen bzw. verbindbaren Papierlage (3) durch die Zwischenlage in Richtung zu der zweiten Papierlage (8) eingebracht bzw. ausgebildet werden. Weiters wird ein derartig hergestellter Papiersack vorgeschlagen, um bei Erzielung einer hohen Luftdurchlässigkeit eine entsprechende Wasserdampfdichte, insbesondere unter Beibehaltung einer notwendigen Festigkeit des Papiersacks, zu ermöglichen.
(EN)
The invention relates to a method for producing a multilayer, partially air-permeable paper sack, which has an intermediate layer (4) consisting in particular of a plastic film or coating, located between at least two paper layers (3, 8). At least the intermediate layer (4) and one paper layer (3) that is/can be attached thereto is configured with a plurality of perforations or breaks (13). According to the invention, the breaks (13) are introduced or configured so that they extend from the paper layer (3) that is/can be attached to the intermediate layer (4) and penetrate said intermediate layer in the direction of the second paper layer (8). The invention also relates to a paper sack produced in this manner, which exhibits good permeability to air, whilst achieving a corresponding impermeability to water vapour and in particular maintaining sufficient strength.
(FR)
L'invention concerne un procédé de fabrication d'un sac en papier multicouche, partiellement perméable à l'air, présentant entre au moins deux couches de papier (3, 8) une couche intermédiaire (4) notamment réalisée d'une feuille ou d'un revêtement plastique, au moins la couche intermédiaire (4) et une couche de papier (3) pouvant être reliée à cette dernière présentant une pluralité de perforations ou de passages (13). Selon l'invention, les passages (13) sont conçus ou pratiqués de manière à s'étendre de la couche de papier (3) pouvant être reliée à la couche intermédiaire (4) vers la deuxième couche de papier (8) au travers des couches intermédiaires. L'invention concerne par ailleurs un tel sac en papier offrant une bonne perméabilité à l'air et permettant une densité de vapeur d'eau élevée correspondante, notamment avec conservation d'une rigidité suffisante.
