This year’s Cannex canmaking technology exhibition, being held in China next month, shows that the business is as vibrant as ever. The Canmaker editorial team reports
Cannex & Fillex Asia Pacific, which returns to Guangzhou in China from 15-18 May 2018, will be the biggest Cannex ever and promises canmakers and other visitors an opportunity to discover a wealth of new technology and processes to help them improve their production efficiencies and to cut costs.
The international showcase for technology, equipment, services and materials for canmakers and fillers will feature more than 200 exhibiting companies offering products and services covering the entire canmaking process – from the provision of canstock, through to the latest two- and three-piece canmaking machinery, forming equipment, along with handling systems, end-making systems and aerosol manufacturing technologies.
Cannex, backed by the publisher of The Canmaker – which this year celebrates its 30th anniversary – will also feature exhibits and services for decorating cans, coatings and systems for testing the integrity of cans produced and controlling their quality. Completing the line-up will be a range of suppliers of ancillary equipment and services, including the latest tooling, lubrication and air systems, designed to help keep factories operating at peak overall equipment effectiveness.
With global sustainability and the ‘circular economy’ under scrutiny from governments, businesses and individuals, the superior recyclability of aluminium and tinplate cans over other packaging materials, will be a particular discussion point at the show. The very latest equipment and systems for reducing and recycling waste materials produced during canmaking will be on display.
Cannex is expected to attract visitors, including chief executives and technical specialists from canmakers and fillers, and consultants, designers and metal packaging professionals, from around the globe. It will provide an ideal opportunity for those attending the show to network with others in the sector, sharing knowledge and information they can take back to their businesses to help drive the profitability of their filling and packaging operations.
Visitors to Cannex who are members of The Canmaker Gold Club will also have free access to the exclusive Gold Club lounge where they can relax and have private business meetings.
This year’s Cannex is the 18th to be held and the fourth time in China, as the nation undergoes momentous change, demonstrating the rapid growth in its commerce and industry – not least within the canmaking sector and its customers in the food and drinks industries.
China’s canmaking business has been experiencing everything that comes with fierce growth, with entrepreneurial zeal leading to overcapacity in some sectors. But its leading canmakers and equipment suppliers are now growing internationally and becoming leaders in their own right.
In the two-piece beverage can sector, global canmakers still find China challenging, but domestically-based firms have risen to become leaders in the sector, such as ShengXing, which has emerged as one of the largest since taking on the management of Pacific Can through its owner.
Showing that innovation is key to gaining a lead is Baowu Steel, which also runs a number of plants making both tinplate and aluminium two-piece cans. To provide short runs of cans that are part of social media promotions it installed a digital printing system supplied by Germany’s Hinterkopf, an exhibitor at Cannex.
The two-piece beverage can market is approaching 40 billion units a year. Cans account for 22 percent of the domestic beer market – the world’s biggest – a share that is still growing.
The sheer size of beverage markets in China such as green tea – more than 12 billion units are consumed each year – have become highly competitive, with JiaDuoBao and Wong Lo Kat fighting for share. One of the biggest canmakers supplying this market is ORG Packaging which has branched out into two-piece beverage cans and bottles, along with filling systems. Its holding company has invested in the acquisition of canmaking operations in Australasia and New Zealand and is expanding production of infant formula cans that are used mostly in China.
The cans that ORG makes for green tea are decorated three-piece tinplate because the product is pasteurised, and these cans are also used for energy drink Red Bull, the second largest brand in China after JiaDuoBao, using some four billion cans a year.
Another discussion point at Cannex is bound to be the impact on the domestic tinplate suppliers in China of the import taxes recently proposed by the US. Some concessions have been made by exempting Canada and Mexico from the tariffs, in response to lobbying pressure. Despite these threats, China’s modernisation programme is unlikely to slow down.
For a nation that produces almost one-half of the world’s steel, the use of metal cans will inevitably remain a pillar of its progressive development. Since 1994, Cannex has been hosted in countries including Thailand, USA, Netherlands, Singapore, Australia and China, where it now returns since it was last here in 2015.
China’s rapid industrialisation is helping to meet the growing expectations of its domestic population, while simultaneously expanding its global export potential. To fulfil the demands of its population for the latest fast-moving consumer goods, companies manufacturing these products are adopting the very latest metal packaging, designs and product functionality that canmakers are now able to provide.
Sayers Publishing Group has been tracking these developments, providing market information and intelligence through its monthly magazine The Canmaker.
