Duplex Coating
Recycled fibre multi-ply folding boxboard consists of a white-pigmented top layer applied over a grey or brown middle and backing structure. This gd2 board features a consistent surface smoothness suited for high-speed offset lithography and complex packaging requirements. Mineral coating treatments provide the necessary opacity to hide the dark reclaimed fibres residing within the inner plies of the sheet.
Uniform printing results depend on the stability of this surface layer during the wetting process.
Production Specification
Mechanical strength properties originate from the long fibres recovered from waste paper streams used in the construction of the middle and bottom layers. Mills calibrate the density of the gd2 board to ensure the material remains rigid enough for automatic filling lines while maintaining sufficient flexibility for precise creasing. Precise control of the moisture content during the drying stage prevents warping that could otherwise interrupt feeding mechanisms in conversion machinery.
Heavy reliance on recovered material makes the structural integrity of the sheet vary based on the specific recycling process employed at the manufacturing facility.
Commercial Application
Consumer goods packaging utilizes this grade because the balanced brightness of the surface provides a professional appearance for retail presentation. Manufacturers select this gd2 board for dry food containers and non-food items where the cost benefit of using recycled fibres outweighs the need for the absolute whiteness found in virgin wood fibre stocks. Consistent caliper allows these sheets to function reliably across a wide range of standard converting equipment without requiring significant pressure adjustments.
Rigid construction ensures that the structural performance remains predictable throughout the lifecycle of the finished container.
