Paper for flat inner layers of corrugated cardboard (interliner) made of 100% thermomechanical pulp is intended for the production of corrugated cardboard for packaging products. The mass of m2 according to TU is in the range from 40 to 100 g/m2 inclusive.
The use of reduced-weight m2 papers in the production of multilayer corrugated cardboard is a modern trend and makes it possible to reduce the specific consumption of components (in terms of m2 of cardboard) without compromising structural strength and to displace more mass-intensive and expensive boxed cardboard used in the production of corrugated cardboard, as well as to reduce the environmental burden and the cost of recycling.
