картон, используется в качестве упаковочного материала. Интенсивность очень высокая. Обычно он желтовато-коричневый. Полу- или полностью отбеленная крафт-целлюлоза светло-коричневого цвета., кремовый или белый. Количественный 80-120G / м2. Длина перелома обычно превышает 6000 М. Сила разрыва, fracture work and dynamic strength are very high. Most of them are web paper, but also flat paper. The Kraft coniferous wood pulp was used as the raw material, which was beaten and made on the long web papermaking machine. It can be used as cement bag paper, envelope paper, adhesive seal paper, asphalt paper, cable protection paper, insulation paper, так далее.
