Patent

CA 2177692

The invention relates to envelopes (3) made from waste paper. To this end, the recycled envelopes (3) are folded from pieces of waste paper obtained directly from paper waste so that its preparation does not require the use of any chemical additives, e.g. bleaches, and the addition of water. According to the invention, the waste paper collected and sorted for this purpose is cut into the sections (1) to be processed further, whereby the section shapes (1) and the position of the fold lines (2, 4, 6, 8) are advantageously laid out according to the waste paper sizes used. As the waste paper requires no laborious processing, the production and use of the envelopes (3) of the invention for postal and other purposes results in a particularly favourable eco-balance.

L'invention concerne des enveloppes (3) fabriquées à partir de vieux papiers. Les enveloppes (3) ainsi recyclées sont pliées à partir de découpes de vieux papiers, elles-mêmes recyclées directement à partir de vieux papiers. La préparation des vieux papiers s'effectue sans aucun additif chimique, tel que des agents de blanchiment, ni addition d'eau. Les vieux papiers collectés et triés à cet effet sont découpés dans des formats de découpe (1) traités ultérieurement. Les formats de découpe (1) et la position des plis correspondants (2, 4, 6, 8) sont conçus, avantageusement, en fonction des formats de vieux papiers utilisés. En renonçant à un procédé complexe de retraitement des vieux papiers, il est possible d'obtenir des enveloppes (3) présentant un éco-bilan particulièrement avantageux sur le plan de la fabrication et de l'utilisation dans le domaine postal ou autre.
