Opal switches salmon packaging to cardboard

Packaging producer and printer Opal has developed a new fibre-based solution to enable Tasmanian Salmon producer Petuna to switch from polystyrene packaging to cardboard, stopping 150,000 polystyrene boxes from going to landfill annually.

The printing uses a new photographic imagery, that was created by combining the technique of reverse printing on a high-quality barrier layer, with the functional coatings process allowing the imagery to be laid down on to the kraft paper.

The image is protected from scuffing and damage through the converting process, resulting in a high-quality finish to the box. Opal says the packaging has resulted in an innovative, sustainable alternative to expanded polystyrene for whole fish packaging and transportation.

Scott Thompson, group general manager Strategy at Opal Packaging, said, “By using Opal’s patented Photo Surefresh process and functionally coated liners, Opal was able to produce a stunning photographic quality branded packaging solution for Petuna.”

Opal’s solution, which contains 55 per cent recycled paper, is recyclable in Australia and New Zealand, and widely accepted through council kerbside recycling collections.

Thompson said the corrugated box was designed with moisture barrier properties to withstand low temperatures for fresh chilled products, approved for airline transportation for export, and suitable for domestic controlled cold chain transportation.

Petuna CEO, Ruben Alvarez, said the new cardboard boxes were made from sustainably sourced paper-based materials locally manufactured and supported in Tasmania.

He said, “Once fully implemented, the new packaging will not only significantly decrease our contribution to landfill, but also reduce greenhouse gas emissions associated with freight due to a 90 per cent reduction in truck movements.”
The new packaging will progressively rollout over the next six months.

Opal was formerly Orora Australasia’s fibre business, which Nippon Paper bought for $1.7bn 18 months ago.
