If you’ve visited Propak Africa over the past four days, you would have noticed the rounded crown of the bowler hat – Bowler Plastics’ signature logo – overlooking the company’s exhibition stand in hall 6. This leading manufacturer of rigid plastic packaging has made the most of Africa’s foremost packaging and printing industry show with the launch of its in-mould labelling, showcased on a variety of PP jars.
Bowler Plastics’ new in-mould labelled jarsP&C Review chatted to Wayne Knutsen, head of injection moulding at Bowler Plastics, about the new offering. ‘The terminology in-mould labelling is directly derived from the technique whereby a pre-printed label is placed into a mould and fused onto the packaging during the injection moulding process. The end result is a high definition, eye catching on-pack design that is virtually limitless in terms of the possibilities.’
Various substrates can be used for in-mould labels; foiled substrates are suitable as are substrates of different thickness. In-mould labels also offer the benefit of saving on virgin polymer in the packaging manufacturing process, because they can be used to give rigidity to a thin walled jar and they enhance barrier properties.
Fast and flexible
High definition imagery on packaging is fast becoming a trend in the personal care industry. With in-mould labelling, brand owners can now have intricate, multi-coloured high resolution images printed on one label, which offers 360° decoration of a jar or tub. And the process occurs in a single step.
‘In-mould labelling is an automated process that also saves on the labour aspect and offers space saving benefits in the warehouse,’ Knutsen explains.
To offer this new service to customers, Bowler has enhanced its injection moulding cavities to accommodate the in-mould labelling process and it has improved the design of its jars in line with market requirements.
A wider variety of options
While in-mould labelling is not new to the market, Bowler Plastics has adopted a new and highly flexible approach, providing the technique on various low cavity moulds and on different shapes. These include lid tops, jar bases and even flip top caps, making two colour caps an accessible reality.
Friedel Sass, Bowler Plastics’ CEO explains: ‘Marketing teams can now use flip top cap innovatively for imaginative displays of brand information. An example of this in the market are the in-mould labels on the top and bottom surfaces of snuff containers sold into Africa. This is not only a marketing tool, but also conveys a safety warning and a brand protection or anticounterfeiting mechanism because the label cannot be pulled off the packaging. Bowler has truly taken this technology to innovatively new levels.’
Knutsen says Bowler Plastics is very excited about the launch of its in-mould labelling project. ‘We’re not replacing any of our existing solutions but rather enhancing our portfolio to meet customers’ needs. By introducing in-mould labelling, Bowler is giving its customers more options to choose from for their packaging requirements,’ he concludes.
