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.
