PACKAGING
PAPER HAS BEEN A VESSEL OF CREATIVITY FOR THOUSANDS OF YEARS Poems, plays, paintings, ancient arts like
origami and the spread of literacy itself all owe a lot to this versatile material. And the creative potential of paper isn’t just being explored in the arts. At James Cropper, the Advanced Materials and Paper & Packaging divisions push the material science of paper beyond its limits, developing innovations for manufacturing, electronics, aerospace and medical applications. But it’s packaging that proves paper is
still the material of the future, even after thousands of years, and we are only scratching the surface of its potential.
THE FOUNDATION OF CREATIVITY In packaging, paper is experiencing something of a renaissance. It is growing in popularity across markets, with consumers paying closer attention to the experience they receive throughout the packaging life cycle than ever before. Naturally, its renewability and widespread
recyclability mean it is easier for consumers to understand its environmental impact when compared to single-use plastic. This also means consumers can enjoy some agency in the fight against waste. When they put paper waste in their bin, they can be reasonably confident that it will be recycled thanks to its high global recycling rate. Given the challenges that exist surrounding the recycling of other materials, especially multi- polymer plastics, this is an important area of innovation for paper. However, this would not be worth much
if paper could not also deliver the level of functional and aesthetic performance that consumers expect. Developing a pack that has a low environmental impact is the easy part. It is much more difficult to do this while ensuring that it can also withstand the journey through the supply chain, and while still looking and performing its best. It’s here that creativity comes to the
forefront. Before the artistic elements of packaging design can be nailed down, brands should engage collaboratively with their packaging and material suppliers to ensure that the material used has the right properties. Materials are the foundation of any packaging project. If they don’t perform as intended, every other element of the project will suffer.
MASTERY AND EXPERTISE Fortunately, paper comes with many benefits that make the ideation and design process more effective. For one, it is highly versatile, meaning it offers unlimited creative possibilities. This is one of the reasons behind paper’s
rapid rise as a luxury packaging material. An Ipsos survey from 2024 found that 69 per cent of consumers perceive products packaged in paper or cardboard as more premium. It is much easier to premiumise a pack made from a material that enables brands to utilise vivid colours, crisp printed designs, a huge range of tactile varnishes, embossing and debossing, foiling and more, all added directly to the pack

through efficient automated converting lines. This kind of freedom means that brands can
work with their material suppliers to ensure every detail is controlled to meet their needs. The exact tactile sensation provided by the fibres within the material, the way it holds dyes and pigments, its weight, the way it looks under different lighting conditions, all of it can be mastered and made to work in a brand’s favour with the right level of expertise.
COLOURING EXPECTATIONS Many of these details are interconnected, requiring a more holistic understanding of materials and their properties. For example, take a fundamental part of any
packaging project, colour. Colour accuracy is much more complex than simply adding a blend of dyes and pigments to a material. First, consider the source of the fibres.
Recycled fibres are increasingly used across all packaging segments in response to consumer demands, retailer guidelines and tightening environmental regulations around the world. However, these fibres can be highly

variable. Fibres sourced from office waste, for example, will likely have been artificially brightened. This whitening agent will still be present in the fibre after recycling and will affect the final appearance of any pigments and dyes used. Even virgin fibres can be subtly different
depending on a number of factors. Different species of trees grown in different parts of the world can produce fibres with slightly different absorbency and strength properties. Naturally, this also has an effect on the look and feel of the finished product in some applications. This can have a surprisingly huge effect
on the final colour accuracy of the finished product when metamerism is taken into account. Metamerism is the phenomenon that causes colours to appear differently under various lighting conditions. What looks perfect on the converting line may look like another colour entirely when viewed under store or home lighting. This effect needs to be tested and accounted for during the material development process.
