Use of Eucalyptus at Kinleith Mill

• Eucalyptus is the hardwood species of choice

for commercial, technical and operational reasons

• Eucalyptus is chipped on site at Kinleith Mill

and pulped in the No3 continuous digester

• Pulping process is NSSC (neutral sulphite semi

chemical)

• High yield (70-75%)
• The eucalyptus pulp is used exclusively on the

No6 paper machine at Kinleith Mill which manufactures kraftliner and semi chemical medium

• Kraftliner and Semi chemical medium are high

performance grades used by the corrugated packing industry in New Zealand

Eucalyptus Pulp and Packaging

• Eucalyptus pulp compliments radiata and recycled pulp

when manufacturing high performance papers

• Eucalyptus pulp improves compressive strength

properties of Kinleith papers, complementing the containability achieved with softwood fibre

• High yield Eucalyptus pulp contains residual lignin

which “sets” during the corrugating process resulting in high strength corrugated board

• Hardwood fibres are shorter than softwood. This

improves corrugator runnabilty and reduces flute fracture

New Zealand Exports

• New Zealand is an exporter of a wide range
• f primary produce
• Kiwifruit, apple, meat, dairy products etc
• Supply chains are often long and include

significant periods in cool storage

• The level of humidity in cool storage cycles

numerous times which stresses packaging

• High performance packaging is critical to the

safe and efficient transport of each product

• Virgin pulp based packaging products are a

durable, cost effective and environmentally friendly solution

• Eucalyptus pulp a key input into Kraftliner

and Semi chemical medium, both of which are tailored for packaging solutions in demanding applications
