Research and Development Laboratory

There is an ultra-modern R&D laboratory at the Printing Inks Plant in Chorula. It operates in the field of:

  • Testing the purity of organic solvents and water content
  • Analysis of volatile organic compounds (VOC) using gas chromatography
  • Determination of organic solvents retention in films, prints, and laminates Specific migration analysis of primary aromatic amines from paperboard, paper, and plastics
  • Examination of global migration from packaging
  • Specific migration study of heavy metals from paperboard, paper, and plastics
  • Elemental composition analysis using ICP/MS
  • Determination of weathering resistance of prints using an aging chamber
  • Determination of color fastness of dyed paper and board according to PN-EN 646 standard
  • Identification of material by FT-IR method
  • Microscopic analysis of the cross-section of packaging, with the possibility of measuring the thickness of the layers
  • Thermal stability testing of materials using a thermogravimeter
  • Determination of glass transition, melting and crystallization temperatures by differential scanning calorimetry (DSC)
  • Determination of the minimum film forming temperature (MFFT)
  • Determination of molar masses and their distribution by gel permeation chromatography (GPC)
  • Determination of lamination bond strength of flexible laminates
  • Determination of static and dynamic coefficient of friction
  • Testing the resistance of prints against sterilization, with the possibility of performing the process over sealed packages
  • Determination of the surface wetting angle
  • Stability studies of colloidal mixtures, including emulsions and dispersions, under elevated temperature with Turbiscan AGS station
  • Analysis of particle size distribution by DLS method
  • Determination of selected rheological properties of substances
  • Testing the resistance to sealing at different temperatures, with adjustable force and pressing time
  • Determination of gloss value at 20 degrees, 60 degrees, and 85 degrees of non-metallic varnish coatings
  • Determination of surface water absorption according to the Cobb test.
