Abstract

Das Teebeutelpapier besteht aus einer ersten Phase von Na­ turfasern mit einem Gewichtsanteil von 60 - 85% sowie einer zweiten Phase von heißsiegelbaren synthetischen Fasern mit dem restlichen Gewichtsanteil von 15 - 40%. Die zweite Phase durchdringt die erste Phase derart, daß beide Seiten des Papiers heißsiegelbar sind, wobei das Flächengewicht des Papiers zwischen 10 und 15 g/m² liegt.
Das Teebeutelpapier besitzt eine verbesserte Teediffusion und ist durch die beiderseitige Heißsiegelfähigkeit auf speziellen schnellen Teeabpack-Automaten verarbeitbar.
