Function of Corrugated Box Body Guard - Protects the value of goods by avoiding damages and waste during logistic chain. Silent Salesman - Gives image and attracts consumers - Conveys image and information and helps consumers choose 4

Basics of corrugated board Corrugated board raw materials Liners Fluting Liners Fluting 5

Liners Function Liner Keeping the corrugated board together Printing base Grades Kraftliner (primary fiber based) Testliner (recycled fiber based) White top liners (Uncoated) New introduction : Clay Coated White Graphical Liners 6

Flutings Function Keeping liners separate => gives great rigidity to corrugated board Fluting Grades Semi-chemical fluting Recycled fiber fluting 7

Fiber base of containerboards Primary Fiber (KLB, Semichem, WTL) Recycled Fiber (Testliner, RCP-Fluting, WTL) Fiber is the base for the characteristics of containerboards. Great variations in quality, so also great variations in boards. 8

Basics of Corrugated Board Packaging Testing ECT Edge crush test FCT Flat crush test BCT Box crush test 11

Factors influencing the box compression resistance BCT BCT Box perimeter ECT Converting operations scoring, slatting, folding, alignment etc Flute formation and bonding Thickness RCT (liner)/cct (medium) of components Converting operations, feeding pressure, printing CMT (medium) (= Flat Crush) Flute formation Flute profile, thickness of components 12

ECT (Edge Crush Test) FOR SINGLEWALL BOARD: ECT = 0.73 x (RCT L1 x α x CCT F + RCT L2 ) + 1.6 R 2 = 90.3 % FOR DOUBLEWALL BOARD: ECT = 0.69 x (Σ RCT L + Σ α x CCT F ) + 2.27 R 2 = 84.3 % WHERE: RCT L1L2 = RING CRUSH TEST VALUES OF LINERS CCT F = CORRUGATED CRUSH TEST VALUES OF FLUTINGS α = TAKE UP FACTOR OF THE FLUTE PROFILE ALL IN KILO NEWTONS PER METRE (kn/m) R 2 = COEFFICIENT OF DETERMINATION = PERCENT FIT 13

Example of corrugated medium matching the needs of the end use Scandinavian i Semichemical i Fluting Pulping method Neutral Sulphite (NSSC) Mainly Hard Wood is used Characteristics ti of Semichem are based on Wood Species used and Pulp Cooking, Fiber Handling and Board Production 14

Characteristics of Scandinavian Semichemical Fluting medium contributing to the box performance and protection of goods Gentle pulping process provide good stiffness Thermoplastic- stiffness increase when corrugated Resistance to high humidity Resistance to changing temperatures Resistance to dynamic loads Purity - no heavy metals - no microbiological growth - no toxic chemicals Stiffness durability during prolonged time - creep 15

Main end uses of Scandinavian Semichem Fluting Fruit and vegetable packaging Other food packaging Electronics Heavy duty corrugated cases 16

Changes in the Corrugated Industry From transport packaging to shelf ready packaging & displays high demand on printing touch & feel Light weighting micro flute Shade brown to white uncoated to coated 17
