This customer of Rosti is the producer of Germany’s favourite ketchup. When the company set Rosti the challenge of re-designing the flip-top closure, improved quality, more consumer friendly opening and integration of the customer logo in high quality print were the top requirements.
To print the famous logo onto the closure, Rosti employed the latest tool designs to eliminate slip agents during the printing process, thus ensuring the highest definition of the two colour design. Since the cap is aligned with the bottle and a second colour is printed on top of the first, the printing also had to be aligned.
Rosti packaging engineers developed a bespoke handling system to align the closure during high volume production. Following successful tests and the start of quantity production, Rosti Packaging is the first precision plastic injection moulder to offer this new technology.
Simply described, plastic injection moulding is a process of melting plastic pellets and injecting it into a mould or cavity to form a shape. Once the shape is formed, the material is cooled, ejected from the machine and – voilà – a finished, functional, esthetically pleasing injection moulded product or part is ready!
