DECORATION AND OTHER COMPONENTS The printing shall be as minimal as possible and shall be carried out with EuPIA-compliant printing inks. Adhesive components such as viewing windows, labels and other plastic components should be avoided. They should be designed in such a way that they can be easily separated in the recycling process or by the consumer. If the packaging is metallised, the metallisation should not cover more than 60% of the packaging surface. Viewing windows and other plastic components that cannot be easily separated from the paper are interfering materials. It is essential to avoid inks containing mineral oil, as these may contaminate the secondary fibres.
CLOSURE SYSTEM Paper tapes can be used as long as the adhesive application does not lead to the formation of problematic stickies12. In general, it is important to use adhesive applications that do not lead to the formation of problematic stickies in the recycling process12. When using staples and plastic adhesive tapes, care should be taken to ensure that they can be separated in the recycling process or in advance by end consumers.
