Abstract

Environmentally friendly paperboard packaging is rapidly increasing its
market share. The growth has been driven by consumers’ knowledge of
ecological materials and consequent change in their consumption
behaviour. Substitution of oil-based materials in the packages with
sustainable alternatives, such as paperboard, has major effects on
package manufacturing processes. With the advancements in digitalization
and automation, the importance of identification and product safety
markings has been emphasized and the integration of markings directly
into packaging materials is desirable. The object of the study was to
investigate manufacturing of small and detailed shapes on surface of the
forming tools using these methods and how deviations on the mould
surface are transferred (i.e. embossed) to the created pattern.
Simultaneously, the impact of manufacturing technology on the process
and parameter selection was investigated. A set of small patterned
forming tools were manufactured from pre-hardened engineering and tool
steel with three different manufacturing methods: precision machining,
electro-erosion and laser engraving. Patterns were formed on the
surfaces of the uncoated and plastic coated SBS-paperboard samples using
a pressing jig designed for the purpose. Trials showed that shape of
the pattern edge is essential for the preservation of the surface layer
of the material. Similarly, the usable pressing force depends on the
pattern edge properties. The results of the study indicate that tested
simple geometry marking patterns can be created on the forming tool
surfaces with commonly used manufacturing techniques.
