Solvent Ink Coding for Aluminium, Blister Foil, PET & OPP | NEOTECH® UAE
Choosing the Right Ink for Variable Coding on Difficult Packaging Surfaces. Industrial Solvent Ink Coding for Non-Porous Packaging | Printing variable information onto glossy, coated or non-porous packaging can require a different ink formulation from ordinary paper-based coding. Applications involving: Aluminium foil Blister packaging PET film OPP PE Metallic stock UV-coated paper Glossy packaging may require solvent-based ink formulated specifically for these surfaces. One example is HSAJET K4022si Thor Black Solvent Ink, which HSA Systems identifies for these substrate categories. Why Substrate Matters A code that prints correctly on porous cardboard may behave very differently on: Plastic film Foil Gloss coatings UV varnish Metallised packaging Important characteristics include: Ink adhesion Drying time Rub resistance Print contrast Surface treatment Line speed Because material names alone do not determine printability, actual samples should be tested. Typical Variable Information Commercial coding systems can be used for information such as: Batch codes Lot numbers Production dates Expiry-related information Product identifiers Traceability codes Barcodes 2D codes Internal manufacturing references The printer/software generates the content; the ink determines whether the resulting mark is suitable for the substrate and process. Featured Ink — HSAJET K4022si HSA Systems positions K4022si Thor Black Solvent Ink for challenging non-porous packaging materials. Current documentation identifies approximately: 45 ml cartridge fill 33 ml average delivered ink 2–3 second drying time, substrate dependent 1-hour decap time 12-month shelf life Important Buyer Guidance Before selecting solvent ink, confirm: Packaging material Coating Surface treatment Print location Conveyor speed Coding machine Cartridge technology Required code durability Environmental exposure Regulatory requirements A substrate sample test is preferable before volume production. FAQ - HSAJET K4022si Q: Why use solvent ink on PET or aluminium? A: Non-porous surfaces generally do not absorb water-based ink like plain paper. Compatible solvent inks are formulated to provide adhesion and drying characteristics suitable for selected non-porous materials. Q: Can one solvent ink print on every plastic or foil? A: No. Even within PET, PE, OPP, aluminium or coated-paper categories, surface chemistry can vary. Testing the actual production substrate is recommended. Q: Is K4022si suitable for blister foil? A: HSA Systems specifically lists aluminium and blister foil among the intended application materials for K4022si.
