German packaging manufacturer Siemer Packaging has expanded its finishing capabilities and sustainable packaging portfolio through the acquisition of Mindener Lackwerkstatt, a specialist in coating, print finishing and functional coating applications.
The move allows the Lower Saxony-based company to bring screen-printing technology in-house and offer a broader range of finishing solutions, including both UV and water-based coatings, for fibre-based packaging applications.
According to Siemer Packaging, the acquisition strengthens its ability to provide customers with customised packaging featuring visual and tactile effects while supporting improved recyclability. The company said water-based coatings represent a more sustainable alternative to conventional UV varnishes, particularly for fibre-based packaging formats.
“The acquisition will be an ideal addition to our portfolio,” said Maren Grondey, who manages the family-owned business together with her sister Laura Grondey.
Until now, Siemer Packaging relied on external suppliers for screen-printing applications, including Mindener Lackwerkstatt itself. By integrating the technology directly into its operations, the company aims to expand the range of decorative and functional finishes available to customers.
“For our customers, this means: even more options for customising packaging, with high opacity, on the most diverse materials, and with special effects that aren’t achievable with offset printing,” said Laura Grondey.
The newly added screen-printing capabilities enable the production of matt and gloss finishes, metallic effects, luminous special colours, tactile varnishes and high-opacity white applications on natural board. The technology also supports the use of water-based opaque whites and coloured coatings created through the addition of colour concentrates.
Siemer Packaging highlighted the environmental benefits of water-based coatings, noting that they use resource-efficient raw materials, are low in odour, suitable for skin and food-contact applications, and are easier to recycle than comparable UV-coated alternatives. The company added that water-based coatings perform particularly well on natural, uncoated cardboard, avoiding the creasing and cracking that can occur with some UV applications.
The acquisition also allows the company to create metallic and glossy effects using water-based clear varnishes containing pigments, eliminating the need for foil stamping and improving the recyclability of the finished packaging.
“The possibilities of screen printing are largely underestimated. With the new machine, we can meet the highest demands for quality and sustainability simultaneously,” said Maren Grondey.
Founded in 1906 and headquartered in Ronnenberg near Hanover, Siemer Packaging produces folding cartons, gift packaging, displays, mailings and other fibre-based packaging products. Through its “Junge Schachteln” brand, the company focuses on sustainable packaging solutions, serving customers including manufacturers in the organic and natural cosmetics sectors.
