TECHNOLOGY

That´s how it works:

  • Special additives to attract dyes
  • Dyes attracted and absorbed during water based coloring process or water based inkjet printing
  • Polymer structure activated for dye penetration
  • Dyes mechanically captured into the polymer structure
  • Uniform coloring is achieved by excellent compatibility of the components
  • High UV/abrasion/solvent/acid resistance due to encapsulation
  • Applicable for PE, PP, PET, A-PET, PET-G and more

That´s what you get:

  • A technology for the reversible and repeatable coloring and decoloring of plastics
  • Optimized plastic recycling rates by decoloring plastics into transparent and white valuable rPlastics
  • The efficient production of colored plastic parts especially at flexible lot sizes (increased efficiency of molding/extrusion process)
  • Decoloring and recycling of dark colors into bright colors possible
  • InPrinting into plastics to avoid additional contaminants
  • Individualisation of unprintable plastics through subsequent InPrinting
  • Heat-sensitive additives or additives that tend to agglomerate in the extrusion process are gently introduced into the plastic by a targeted migration process and distributed finely and homogeneously.

COLORING

The key-locker principle of subsequent coloring of plastic films, parts or general objects bases on the ability of these plastics to firmly store organic and/or inorganic components such as dyes in the plastic matrix. The plastics receive this ability by the addition of corresponding additives. Furthermore, suitable dyes are needed that migrate under certain conditions but do not show any unintentional bleeding. The basis of our technology for the reversible coloring of plastics is therefore a selected additive-dye combination.

INPRINTING

The ba­sics of In­Print­ing are com­par­able to col­or­ing. The plastic is prepared for dye encapsulation, but the ac­tiv­a­tion of the sur­face is done by IR. The In­Print­ing Tech­no­logy is de­veloped for the use of di­git­al print­ing with wa­ter­ based inkjet. With InPrinting we are using all the ad­vant­ages that the plastic matrix of­fers - scratch/solvent/UV- resistance etc.. In­Print­ing means en­cap­su­la­tion!

DECOLORING

Plastics that have previously been colored by Smart Coloring Technology can be decolorized. The decolorization, the resolving of the dyestuffs, takes place in an aqueous decolorizing bath at elevated temperature with the addition of dye absorbing systems.
The plastic "opens" and releases the dye. The dye is absorbed and removed from the washing water. Plastics can be re-colored due to the remaining additive. Accordingly, it can make sense to decolorize plastic parts as a whole and to dispense with shredding.
