Abstract
The invention relates to a paper profile (1), in particular for a packaging element or packaging equipment of food packaging. The paper profile (1) has an elongated shape. The paper profile (1) is formed by at least one round or almost round, flexurally rigid paper rod (3) or a plurality of round or almost round, flexurally rigid solid paper rods (3). The flexural rigidity of the paper profile (1) corresponds in at least one bending direction to the flexural rigidity of one of the rigid paper rods (3).
Claims36
A paper profile for use as a packaging element or packaging equipment for food packaging, wherein said paper profile has an elongated shape having at least one long side in longitudinal direction, at least one narrow side in transverse direction, and a profile thickness in a transverse direction, characterised in that the paper profile is formed from two or more paper rods, each of said papers rods have substantially no hollow spaces, each of said paper rods is a flexurally rigid roll prior to being used in said paper profile, wherein the flexural rigidity of the paper profile in at least one bending direction corresponds at least to the flexural rigidity of one of the paper rods, and wherein a restoring force counteracting the bending direction can be generated at least in sections by bending the paper profile, a plurality of said paper rods have a same cross-sectional size and profile along a longitudinal length of said paper rods, a final cross-sectional shape of a plurality of said paper rods is selected from the group consisting of a circular shape, oval shape and stadium shape.
A paper profile for use as a packaging element or packaging equipment for food packaging, wherein said paper profile has a top, a bottom, a first side, an opposite second side, a first end and an opposite second end, said paper profile having an elongated shape;
- said paper profile including first, second and third paper rolls, each of said first, second and third paper rolls has substantially no hollow spaces, each of said first, second and third paper rolls is formed of a rolled-up web of paper, said each of said first, second and third paper rolls have substantially no hollow spaces prior to being used in said paper profile, said first, second and third paper rolls have a same cross-sectional size and profile along a longitudinal length of said paper rods, a cross section shape of said first, second and third paper rolls in a final form of said paper profile is selected from the group consisting of a circular shape, oval shape and stadium shape, each of said first, second and third paper rolls having a longitudinal length that is greater than a diameter or width of said first, second and third paper rolls, and wherein said paper rods substantially maintain their cross-section shape when forming said paper profile.
