Six Key Factors in The Liquid Paperboard Market

Production of liquid paperboard reached 7.2 million tonnes in 2016, equating to a value of $9.5 billion to the paper mills. Production of these materials is highly concentrated, especially liquid packaging board, which is produced in only ten countries around the world.

As with other packaging sectors, there is an impetus for suppliers to develop new processes and technologies that can enhance overall packaging designs and reduce the cost of manufacture. According to Smithers Pira’s (smitherspira.com) new report, “The Future of Liquid Paperboard to 2022,” there are several major trends and issues that are disrupting the industry.

Sustainable barrier coatings

Liquid paperboard is providing a key market application for barrier coating materials that has a reduced environmental impact.

Several biopolymers have already been commercially trialed in coatings for paperboard. The most promising polymers identified were polyhydroxybutyrate (PHB) and polylactic acid (PLA). These two materials offer the best results, in terms of a consistent, thick and continuous layer, for extrusion coating, while other materials are better suited to dispersion and solvent casting.

Smaller pack sizes

Social changes are affecting packaging demand in unexpected ways. There is an increasing need for greater convenience and a growing demand for ready-to-drink and on-the-go foods and beverages. The result is a growing demand for smaller pack sizes in numerous food and beverage sectors.

Smaller packs consume more liquid paperboard to pack the same given quantity of product, leading to an increase in raw material consumption. Furthermore, these smaller packs consist of a greater surface area of material that requires more inks, adhesives and other consumables, stimulating value-added for converters.

Competing materials

Competition from glass packaging and fluctuations in the price of aluminum are having a degree of influence on both liquid packaging board and multi-substrate flexible pouches.

Liquid packaging board faces competition from specific packaging formats and the latest of these is the clear retortable plastic can. This is likely to have a limited impact on the liquid paperboard market, but it does pose a threat to the retort carton, which has shown significant opportunities.

Recyclability

Latest reports indicate that recycling has improved from 20.1% to 23.6% over the last five years since 2012. This growth is demonstrated in the UK with 92% of the country’s 391 local authorities now collecting cartons, with two-thirds offering curbside collection, up from 4% in 2006. In the U.S., recycling continues to improve, with almost 68 million households able to recycle beverage cartons. This represents 58% of households, up from only 18% in 2009.

Governments and beverage brand chains are increasingly pushing for recyclable hot beverage cups. A recent innovation in mid-2016 has seen Starbucks trial a fully recyclable cup as part of its efforts to reduce waste sent to landfill, as well as to improve its environmental profile.

Sustainability

A broad trend across the packaging industry is to minimize the environmental impact of packaging, which is stimulating both technical innovations and new business models across the value chain.

This interest includes consumers – especially millennials – brand owners, converters and regulators and spans a number of different means to realize the goal of furthering the use of sustainable, recyclable and compostable packaging into the mainstream.

Reduction of packaging waste can be achieved by various means, including lightweighting and by utilizing materials that are themselves sustainable, as in renewable and recyclable. This has been perceived to be an advantage of liquid paperboard, but new understandings of how polymer coatings inhibit this process, and the arrival of competing formats optimized for sustainability is threatening this.

Healthy eating trends

In efforts to reduce welfare costs, various governments are endorsing healthier eating lifestyles and promoting healthier habits, which are being adopted by many consumers. The EU has targeted a 16% reduction in salt for processed foods, while the UK reduced the average consumption of salt by around 5% across 2005–2011.

Consumers have become more sensitive to prices, which has become evident in the strongly competitive food retail industry. In Western Europe, private labels are increasingly popular and are becoming a brand in their own right. The initial advantage that traditional brands had over private labels was the perceived quality differential, which still exists to differing extents in some countries, but is most evident in Italy. However, demand is changing, largely due to the poor economic climate. In addition, the improved quality branding of private labels has helped to put them on par with their branded equivalents.
