PAPER AND CARDBOARD
The boards for flat layers
The boards for flat layers and the papers intended for corrugation are manufactured on the K-28 machines and equipment used for cardboard production that were put into operation in accordance with the State Acceptance Committee Act No. 561 dated 30.12.1988. In January 1989 we commenced production of the first tons of cardboards.
Papers for corrugation
The paper intended for corrugation is used for production of inner corrugated layers as part of corrugated boards. For production of corrugated boards we can currently use also the paper called fluting.
The paper mill ANGREN PACK produces papers for corrugation with substances of 100 – 125 g/m2.
Boards for flat layers
The boards for flat layers are used for production of inner and outer layers as part of corrugated boards. The flat layers fix goffered corrugated layers in position, absorb diverse internal and external loads and keep the given shape of the corrugated board. Board strength and appearance depend on board quality. The paper mill ANGREN PACK produces papers for corrugation with substances of 140 – 300 g/m2.

1. Top layer – liner
