High standards for children’s toys – Openair® Plasma means safe processing and ink adhesion.
“Printed ink that chips or flakes off a toy can quickly land in a toddler’s stomach.” That statement by a well-known toy manufacturer is indicative of the high safety standards required of children’s toys. This means that the ink systems used must comply with the same requirements as those applied to food colourants. At the same time, no toxic stabilisers, like lead, can be used in the production of plastic parts for toys.
So innovative manufacturing processes are required to ensure quality adhesion of printing ink, while also meeting the general challenges of cost-efficient manufacture of the toy.
Using Openair® Plasma, the high surface tensions required for processing the most diverse materials can be precisely achieved, and most importantly with a purely physical process, free of chemicals. Water-based inks adhere beautifully with long-lasting stability.
