TWIST & WRAP
It is important that today’s wrapping machines offer the flexibility to handle a variety of different wrapping tasks.
The changing twist wrap world
Kennedy’s Confection spoke with Steffen Hamelmann, marketing manager at Theegarten- Pactec about today’s twist wrap packaging solutions.
KC: Flexibility is now a key word for all confectionery production equipment. How has twist wrap packaging technology evolved/changed to meet the need for greater flexibility without impacting productivity?
SH: Absolutely right! Flexibility is not just a trend in the field of double twist wrapping, but in packaging technology in general. In recent years, Theegarten-Pactec has been working to develop high-performance machines that can be converted to several different wrapping tasks. So, today’s packaging machines ideally need to be able to switch between up to nine different folding styles at outputs of up to 1,800 products per minute. For seasonal production, for example, this means there would be no need to invest in several different packaging machines. One application could be for the wrapping of chocolate balls in double twist wrap for Christmas. On the same machine, however, Easter eggs could also be wrapped in foil wrap for the springtime confectionery season. Of course, choosing a more flexible packaging machine also makes it much easier and more cost-effective to respond to ever shorter product lifecycles and fast-changing market requirements. Think how much more flexible an operation could be if the packaging equipment could be converted to other wrapping styles and/or other product formats instead of having to invest in new machines for product variants. However, depending on the specific application, single-purpose machines for double twist wrap can still an appropriate choice. For products with international sales markets with high outputs, machines that exclusively perform double- twist wrapping can still be a good option.
KC: Has there been a need to adapt twist wrapping machines to handle the latest generation of sustainable film/wrapping materials? Do new materials pose problems on wrapping machines? SH: We are certainly seeing a trend towards sustainability in the confectionery industry which of course also affects packaging technology. It is important to understand that sustainability and profitability are not mutually exclusive, but rather they should complement each other. For example, in the past we have developed machines to work with ever thinner twist wrapping materials. Today, there is a need to adapt again, to meet the requirements that now arise from the growing trend towards paper-based materials. It is important that the sensitive packaging material must not tear, even at high wrapping speeds. We are, therefore, in constant discussion with packaging material producers regarding the development of fully recyclable packaging materials and a host of new wrapping materials. It is important that we test new developments on an industrial scale for all new materials and, if necessary, we may need to make modifications to the machines in order ensure optimal wrapping speeds and quality.
